CNC machined faceplates

CNC machined faceplates for the SSB6.1 transceiver kit

This relatively new home brew transceiver kit from indo-ware offers a six HF bands and CW/LSB/USB modes. All interested for DIY can obtain the major boards on e-bay. Also, there is a great support group on Facebook.

For many, the biggest problem is to install the finished product into the appropriate box with a professional look. The first contact with any device will be through its front panel, so the first impression will be proportional to the effort you put into a look of the front panel. In the photos below, you can see a few examples of CNC machined front and back panels. The general dimensions are adaptable to suit your needs while design remains the same, given the type of DDS used for that transceiver.

If you need the front or the back plate for SSB 6.1 transceiver kit, or both of them, or maybe a front plate for any other device you built, please contact me at: emu.9a2gb(at)gmail.com

MR300 HF Antenna Analyzer


MR300 HF Antenna Analyzer

I have found this interesting HF Antenna Analyzer on our colleagues web site, Chinese amateur radio BG2XNN, Jason. I have to say that deal with Jason was pleasant, also delivery was a very quick. It took no more than 7 days, from China to Croatia. MR300 is not just antenna analyzer, it can measure capacity, inductance and other complex measurements on the antennas in the frequency range of 1 to 60 MHz.

I made a few quick tests with 50 Ohm dummy load (1-500 MHz), comparing MR300 measurement results with results measured on AW07A and on MFJ-259B, using the same dummy load.

All three devices have yielded an identical results in a measuring range of 1.8 to 54 MHz (SWR 1:1, impedance of 50 Z). MR300 is easy to use, very intuitive and has SCAN possibility (not found on the other two devices).

Measuring test on 6m / 50 MHz open dipole
Measurement was conducted on the reference open dipole antenna with known impedance (Z=75), SWR (1:1.5), on frequency of 50.150 MHz
Here are a measurement results:

MR300: SWR 1:1.49, Z = 76
AW07A: SWR 1:1.52, Z = 76
MFJ-259b: SWR: 1:1.51, Z = 75

These very small differences in the measured results found on all three devices are within declared tolerances. For amateur use all three devices are recommended. Differences are in the measurement range, measurement possibilities, and of course in the price.

More about MR300 can be found on Jason’s website.

What’s new in GBCAT v1.32?

Aside

What’s new in GBCAT v1.32?
(Article written in English, Italian, Croatian and Russian language)
Download GBCAT here.

New features:

  • Added suGBCAT.Yaesu.Featurespport for Yaesu FT-817ND, a younger brother of Yaesu FT-817.

Some differences between FT-817ND and FT-817:

  1. Display Color (Blue/Orange/Violet)
  2. Display Contrast: This control use an unusual but the only possible way to change a Contrast value. After a new value is selected, your Rig will be turned off and switched on, to accept a new value. It will work as described only if power is supplied via the rear power connector. I don’t like it, but it is the only way (known to me) how this control can be implemented.
  • Kenwood TS-2000: LOCK button is now 3-state button. If TS2K is unlocked (which is default), the 1st. click on LOCK button = F.LOCK, the 2nd. click = A.LOCK, and the 3rd. click = UNLOCK state. (Thanks to Mike, WB7QBF)
  • All rigs: Resume from Sleep or Hibernate. GBCAT will try to reinitialize a communication link with your rig after resuming from Sleep or Hibernate state. Saved in GBCAT.cfg, as the configuration option.
  • All rigs: Registering GBCAT now in a three easy steps. No more searching for GBCAT installation folder.
  • Yaesu FT-817/ND New Button M/V: Switch between Memory and currently active VFO. Not tested with the older models.
  • Yaesu FT-817/ND New Feature: Select and invoke desired Memory channel. Use Combo box “MEM CH” for selection and button “Set MC” for confirmation. Not tested with the older models.
  • GBCAT.Yaesu.Features.FT.817ND.Memory.ManagerYaesu FT-817/ND New Feature: Memory Manager. Follow instructions! Not tested with the older models.

Italian language, (thanks to Silvio, I2SU):

GBCAT v1.32
Nuove caratteristiche:

– Aggiunto il supporto per lo Yaesu FT-817ND, il fratello più giovane dello Yaesu FT-817
Differenze tra FT-817ND e FT-817:

  1. Colori del Display (blu / arancio / viola) 2. Contrasto del Display : Questo controllo utilizza un’ insolito, ma unico modo possibile, per modificare il valore del contrasto. Dopo la selezione di un nuovo valore, il vostro apparato si spegnerà e poi verrà riacceso, per fargli accettare il nuovo valore. Funzionerà come descritto solo se l’alimentazione viene fornita tramite il connettore di alimentazione posteriore. Non mi piace, ma è l’unico modo (a me noto) come questo controllo possa essere implementato.

– Kenwood TS-2000: LOCK è ora un pulsante a 3-stati. Se il TS2K è sbloccato (che è l’impostazione predefinita), il primo. click sul tasto LOCK = F.LOCK, il 2 °. click = A.LOCK, e il 3 °. click = Stato di SBLOCCO. (idea di Mike, WB7QBF)

– Tutti gli RTX : Riattivazione dallo stato di sospensione o di ibernazione. GBCAT tenterà di reinizializzare un collegamento  della comunicazione con il vostro apparato dopo il ripristino dalla modalità Sospensione o Ibernazione. Salvato in GBCAT.cfg, come opzione di configurazione.

– Tutti gli RTX: La registrazione di GBCAT avviene ora in tre semplici passaggi. Non più alcuna ricerca della la cartella di installazione di GBCAT.

– Yaesu FT-817/ND Nuovo pulsante M/V: Commuta dalla memoria al VFO attualmente attivo. Non testato sul vecchio modello.

– Yaesu FT-817/ND Nuova funzione: Seleziona e richiama il canale di memoria desiderato. Utilizzare il Combobox “MEM CH” per la selezione ed il pulsante “Set MC” per la conferma. Non testato sul vecchio modello.

– Yaesu FT-817/ND Nuova funzione: Memory Manager. Seguite le istruzioni! Non testato sul vecchio modello.

Bug corretti:

– Tasto Yaesu FT-817 Set AF (Antenna anteriore / posteriore), strano comportamento se venivano collegate entrambe le antenne, ora lavora come previsto.

Yaesu FT-857, FT-897, FT-817: DISC (discriminatore) ora lavora come previsto, solo nelle modalità FM.

– Per tutti gli Yaesu ed i Kenwood supportati: una grafica idonea dell’ S-meter  viene richiamata dal pulsante “S”, se nel frattempo viene cambiato il modello di RTX.

– Per tutti gli Yaesu ed i Kenwood supportati: Corretto il Bug nella immissione diretta della nuova frequenza e il metodo è migliorato: Una maschera appropriata per il campo di input viene selezionata all’avvio di GBCAT. L’immissione della nuova frequenza può essere effettuata sia con la tastiera del PC che con i tasti numerici verdi GBCAT. Grazie ad Alex, RA2FKD.

– Yaesu FT-817/ND il cursore del controllo della potenza: i valori di potenza ora sono mostrati lato del cursore della Potenza, a sinistra il più basso e a destra il più alto . Grazie ad Alex, RA2FKD.

– Kenwood TS-2000, Analizzatore di spettro: la bandierina della Frequenza ora viene riportata in Ghz, senza lo zero iniziale.

– Yaesu FT-817/ND, migliorato il backup della EEPROM.

– Tutti gli apparati: Migliorato “About”, come espressione di gratitudine per tutti i generosi donatori di GBCAT . Grazie ragazzi!

Hrvatski jezik:

GBCAT v1.32

Nove značajke:

– Dodana podrška za Yaesu FT-817ND, mlađeg brata Yaesu FT-817

Neke razlike između FT-817ND i FT-817:
1. Boja predočnika (display) u FT-817ND je plava ili narančasta ili ružičasta.
2. Kontrast predočnika: Ova kontrola koristi neuobičajen način za promjenu vrijednosti tj. boje predočnika. Nakon što se unese nova vrijednost, vaš uređaj će se ugasiti i ponovo upaliti, kako bi prihvatio novu vrijednost. Ovo će raditi samo i jedino ako se uređaj napaja na stražnjem priključku za napajanje. Osobno ne sviđa mi se ovo rješenje, ali to je jedini, meni poznati način da se implementira kontrola promjene boje predočnika.

– Kenwood TS-2000: LOCK dugme sada ima 3 radna stanja. Ako uređaj nije zaključan (što je standardna postavka) onda je:
prvi klik na LOCK dugme = F.LOCK,
drugi klik na isto dugme = A.LOCK, i
treći klik na isto dugme = UNLOCK state. (ideja: Mike, WB7QBF)

– Svi podržani uređaji: Resume, Sleep, Hibernate. GBCAT će pokušati inicijalizirati komunikaciju sa vašim uređajem nakon izlaska iz bilo kojeg od gornja tri nabrojena stanja. Ova postavka sprema se u GBCAT.cfg, kao standardna konfiguracijska postavka i može se mijenjati iz menija.

– Svi podržani uređaji: Registracija GBCAT-a od ove inačice vrši se u tri jednostavna koraka. Nema više traženja GBCAT instalacijske mape i muke oko postavke vidljivosti iste, za što je kriva standardna postavka u operativnom sustavu.

– Yaesu FT-817/ND, novo dugme M/V: Prebacivanje između trenutno aktivnog VFO-a i memorijskog kanala. Nije testirano na starijim modelima.

– Yaesu FT-817/ND nova značajka: Izaberi i postavi željeni memorijski kanal. Koristite “MEM CH” combobox za odabir i dugme “Set MC” za potvrdu tj. postavljanje željenog memorijskog kanala. Nije testirano na starijim modelima.

– Yaesu FT-817/ND nova značajka: Memory Manager. Slijedite instrukcije! Nije testirano na starijim modelima.

Ispravljene greške:

– Yaesu FT-817, dugme Set AF (Antenna Front/Rear), čudno ponašanje ako su obje antene priključene sada je ispravljeno i radi prema očekivanju.

– Yaesu FT-857, FT-897, FT-817: DISC (dikcriminator) sada radi prema očekivanju, samo u FM modu.

– Svi podržani Yaesu i Kenwood uređaji: Odgovarajuća prednja ploča za S-metar sada će biti ispravno učitana, ako je u međuvremenu došlo do promjene odabira uređaja.

– Svi podržani Yaesu i Kenwood uređaji: Greška kod direktnog unosa nove frekvencije je popravljena, a unos je poboljšan. Odgovarajuća maska poziva se za polje unosa kod samog pokretanja programa. Unos nove frekvencije može se izvršiti i sa PC tipkovnice i koristeći GBCAT-ove zelene numerička dugmad. Hvala Aleksu, RA2FKD.

– Yaesu FT-817/ND, klizač Power kontrole: Vrijednost snage sada su prikazane od lijeve ka desnoj strani, od najmanje ka najvećoj. Hvala Aleksu, RA2FKD.

– Kenwood TS-2000, Bandscope: Vrijednost frekvencije na zastavici sada je prikazana u kilohercima, bez nule kao vodilje.

– Yaesu FT-817/ND, poboljšan EEPROM backup.

– Svi uređaji: izmijenjen “About”, kao izraz zahvalnosti svim velikodušnim GBCAT donorima. Momci, hvala!

Gradimo CNC stroj, III dio

Steppers.and.controllersGradimo CNC stroj
III dio

Montaža sigurnosnih mikro-sklopki

Stara poslovica kaže: “Bolje spriječiti nego liječiti”. Primijenjeno na ovaj naš slučaj, pored mogućnosti da softverski postavimo krajnje granice gibanja po pojedinoj osi, postaviti ćemo i sasvim obične ali vrlo efikasne mikro-sklopke, koje neće dozvoliti da pogonsko navojno vreteno na nekoj od osi dovede nosač druge osi ili nosač motora u jedan od dva krajnja položaja i na taj način polomi stroj. Kakva je moguća šteta, ako bi se to ipak dogodilo? Na ovo pitanje ima nekoliko odgovora, a prvi se nameće sam od sebe. Sve ovisi o spojnici koračnog motora s pogonskim navojnim vretenom pojedine osi. Ako su spojnice suviše krute, postoji mogućnost da svornjak u spojnici (ili dva, kao u našem slučaju) “odere” osovinu motora ili pogonskog navojnog vretena, ili oboje. Ako spojnica nije previše kruta, puknuti će, i možda spasiti stroj. Ako se ne dogodi ni prvo ni drugo, vjeratno će doći do oštećenja pogonskog navojnog vretena, i/ili ležajeva i/ili bočnih nosača osi. Može doći i do pregaranja koračnog motora ili kontrolne elektronike, pa zato nikad ne ostavljajte hobby CNC stroj bez nadzora.

X-axis.microswitchesS obzirom da naš CNC stroj iz primjera ima 3 osi, (X, Y, Z), potrebne su nam 3×2=6 mikro-sklopki. Za osi X i Y odabrao sam robusne mikro-sklopke s valjčićem na limiću za okidanje sklopke. Nažalost, zbog ograničenog prostora na Z osi, nisam imao previše izbora, nego sam montirao dvije mikro-sklopke koje su se uklapale u ograničavajućih
21 mm prostora. Mehanički, sve mikro-sklopke pričvršćene su vijkom M3 na pokretne nosače osi, čime se gubi potreba za dodatnim razvlačenjem spojnih kablova, jer su veze s kontrolnom elektronikom koja prekida rad motora već provučene zajedno s pogonskim kablovima koračnih motora. Na ovaj način smanjuje se “šuma kablova”, a efikasnost je
jednaka kao kad se mikro-sklopke postave na fiksne dijelove stroja. U ovom slučaju, mikro-sklopke su “pomične”, a graničnici koji izazivaju uključenje mikro-sklopke i prestanak gibanja po osi su fiksni.

Y-axis.microswitchesNe bih rekao da je ovakav način inovativan ili neobičan, prije bih rekao da je neobičan nedostatak rupa s navojem, predviđenih za montažu mikro-sklopki, jer ih u ovom mehaničkom kitu jednostavno nije bilo. Bio sam primoran izbušiti 6 rupa od 2.5 mm i urezati M3 navoj u svakoj od njih, na mjestima koje sam odabrao za montažu mikro-sklopki. Ako izuzmemo lom jedne ureznice, sve je bilo uspješno, pa sam prešao na iduću fazu.

Y-axis.stepperMontaža koračnih motora i motora glavnog pogona

Koračni motori su proizvod svjetski poznatog kineskog proizvođača koračnih motora “Longs Motor”, tipa Nema23, snage 425 oz. po inchu (model Longs 23HS9430B) u dual-shaft izvedbi (dvije osovine). Kit koji je kupljen posebno, sastojao se od 3 takva koračna motora, 3 komada 128-mikrostep kontrolera i napajanja za sva 3 motora, 36V/10A.

U mehaničkom kitu, na sreću, nalazili su se i držači za montažu koračnih motora. Lijepo oblikovani, funkcionalni, ali od plastike. Ovaj “ali” ću kasnije izbaciti iz rečenice, jer su jednako dobri kao da su metalni. Za svaki slučaj, naručio sam i metalne valjke od A2-Inoxa, promjera 10 mm, debljine stjenki 2 mm, dužine 40 mm, ukupno 12 komada, kao “konstrukcijski backup”, ako mi se učini da plastični nisu od koristi. Kasnije, kad sam motore već montirao, ustanovio sam da cijeli stroj mogu podignuti na način da uhvatim za jedan koračni motor vezan na bočnu stranicu osi upravo s tim plastičnim nosačem, bez vidljivih posljedica u obliku deformacije nosača motora.

Ono što ne dolazi u mehaničkom kitu je potrebnih 12 komada M5 vijaka (isto iz A2-Inoxa) s imbus glavom dužine 60 mm. Također, morao sam kupiti A2 podloške za M5 vijke kao i tzv. “špreng” podloške, tj. prevedeno na standardni hrvatski jezik, elastične rascjepljene podloške, kako se učvršćenje motora u radu nebi opustilo zbog vibracija.

Pored držača motora, vijaka i podložaka, za montažu su potrebne i tri rigidne spojnice. Ove spojnice napravljene su od jednog komada aluminijskog valjka s provrtom od 8 mm na obje strane koji je “prošlican” poprečno u spiralu od 5 navoja. Na taj način ova rigidna spojka više i nije takog “rigidna” ili kruta, nego u radu kompenzira pomake koračnog motora naprijed ili nazad, tj. ponaša se kao elastična spojka. Zanimljivo rješenje, jer sam na svom prvom CNC hobby stroju koristio spojnice napravljene u obliku kardanske spojke, s kompenzacijskom masom od guma-plastike. Oba rješenja su dobra, a ovo sadašnje je malo jeftinije.

Motor se na bočnu stranicu osi montira na način da se prvo na navojno pogonsko vreteno montira rigidna spojnica, zatim se na motor utisne plastični nosač, kroz rupe na nosaču provedu se M5x60 vijci sa podloškama a osovina koračnog motora se vrlo nježno utisne u provrt rigidne spojnice. U ovoj fazi, pri ruci obavezno treba biti dugački imbus ključ kojim se M5 vijci metodom nasuprotnog zatezanja privinu u bočnu stranicu osi. Kad sve sjedne na svoje mjesto i M5 vijci su čvrsto privijeni, privijemo i svornjake u rigidnoj spojnici, kako bi pričvrstili osovinu koračnog motora u spojnici. Ovaj postupak ponovimo još točno 2 puta, za preostale osi. Kako su koračni motori u “dual-shaft” izvedbi, (imaju osovine na oba kraja motora), ako i sada možemo pokretati osi samo snagom prstiju vrteći vanjsku osovinu koračnog motora koja je preko rigidne spojnice vezana na pogonsko navojno vretno osi, onda je sve u redu.

Steppers.and.controllersPostavljanje i spajanje pogonskih i signalnih kablova

Čitajući forume koji se bave CNC tematikom i samogradnjom CNC hobby strojeva, nekoliko puta sam pronašao opise problema ljudi koji su koristili tanke tj. neadekvatne kablove. Pod time mislim na sve kablove koji ne mogu adekvatno prenjeti napon i struju od kontrolne elektronike do koračnog motora. Kao i kod vodovodnih instalacija, gdje je poznato da kroz tanku cijev za vodu ne možemo napajati 100 kuća već samo jednu, tako je i kod električnih instalacija, gdje se koristi Ohmov zakon koji kaže da će jakost struje kroz vodič biti to veća što je veći napon među njegovim krajevima i što je manji otpor strujnog kruga u koji je vodič uključen, tj. da je jakost struje u strujnom krugu proporcionalna naponu, a obrnuto proporcionalna otporu. Matematički, ovo se može izraziti slijedećim formulama:

I = U/R  ili  U = IR  ili  R = U/I, gdje su:

I = jakost struje kroz strujni krug u amperima (A)
U = napon izvora u voltima (V)
R = ukupan otpor strujnog kruga (otpor trošila + otpor električnih vodova + unutarnji otpor izvora struje) u omima (Ω). Om se može napisati i kao volt/amper (V/A).

S obzirom da proizvođač koračnih motora daje podatak o potrošnji od 3A po fazi, moramo omogućiti da se napon napajanja kod nazivne struje od 3A sa što manje gubitaka prenese od kontrolne elektronike do koračnog motora. Kod gotovih CNC strojeva proizvedenih u Kini, vrlo često se koriste tanke (jeftine) žice površine od 0.5 ili 0.75 kvadratnih mm, što je nedostatno. Tko se bavi elektronikom, iz prakse će znati da se za prijenos istosmjerne struje jačine od 2A mora osigurati bakreni vodič presjeka od 1 kvadratnog mm. Za prijenos istosmjerne struje od 3A, potreban je vodič presjeka od 1.5 kvadratnih mm. Ako se koristi tanji vodič, manjeg presjeka, rezultati su greške u radu koračnog motora u vidu gubljenja impulsa, smanjene snage koračnog motora itd. Izgubjeni impuls ujedno znači i nepreciznost u radu, jer je broj učinjenih okretaja koračnog motora direktno ovisan o broju primljenih impulsa.

Za spajanje svakog koračnog motora s kontrolnom elektronikom koristio sam visoko fleksibilni kabel za električne instalacije 4×1.5 mm kvadratnih sa teflonskom izolacijom, tj. po 4 Cu fleksibilne žice (licna) dužine 4×2 metra, ukupno 24 metra Cu fleksibilne žice u 4 različite boje za sve koračne motore. Spojeve sam izveo lemljenjem kvalitetnih muških i ženskih raznobojnih stopica, koje mogu prenjeti veliku struju bez gubitaka i na taj način osigurao i rastavnost spojeva, pored adekvatnog prijenosa struje kod nazivnog napona. Također, za spajanje pogonskog motora glodala, mikro-sklopki i Tool-senzora potrošio sam dodatnih 14 m Cu žice, što je ukupno 38 m utrošene izolirane Cu žice. Sve žice provode se putem kvalitetnih konektora, od panela kutije s kontrolnom elektronikom do koračnih motora, upakirane u tzv. “plastične lance”, tj. unutar gibljivih plastičnih, međusobno povezanih modula koji osiguravaju fleksibilnost i drže spojne žice na okupu. Korištene su 4 različite boje žice, kako bi svaka od pojednih faza na koračnom motoru bila spojena na točno odgovarajuće mjesto. Na kraju polaganja potrebnih kablova, svi spojevi provjereni su ohm-metrom.

CNC.electronics.in.PC.chasisMontaža kontrolne elektronike i napajanja u staro PC mini-tower kučište

S obzirom da sam u mojoj “furdi” pronašao jedno staro PC mini-tower kučište, odlučio sam dodatno uštedjeti i iskoristiti tu kutiju koja se godinama prebacivala amo-tamo i konačno dočekala da bude iskorištena kao kutija u koju ću montirati slijedeće:

BOB– BOB elektroniku, (Break-Out-Board), tj. elektroniku koja preko paralelnog porta (printer port) prihvaća impulse od upravljačke programske potpore Mach3 i prosljeđuje ih na pojedine kontrolere koračnih motora.
– 3 komada 128-mikrostep kontrolera
– napajanje za sva 3 koračna motora 36V/10A
– napajanje za glavni pogonski DC motor (nosač obradnog alata), 48V/8.3A
– upravljački panel s konektorima, osiguračima, emergency sklopkom za trenutno zaustavljanje svih osi, naponskim prekidačima.

Controllers.wiringSve od nabrojenog već je predviđeno za ugradnju i pričvršćenje vijcima, pa mi je samo preostalo da izmjerim sve razmake između postojećih rupa, mjere precizno prenesem na lim PC kučišta i izbušim rupe odgovarajućeg promjera. Što pažljivija izmjera, to manje čupanja kose kod montaže pojedinih dijelova.

Spajanje BOB elektronike (Break-Out-Board) s kontrolnom elektronikom i napajanjem te spajanje kontrolne elektronike s koračnim motorima provedeno je prema shemama dobijenih od proizvođača, koje nisu uvijek bile “do zadnje žice” precizne. Ono što je bilo nejasno, nadopunjavao sam saznanjima drugih ljudi koji su svoja iskustva u  spajanju elektronike i koračnih motora nesebično podijelili s drugima. Ja objavljujem shemu spoja kako je spojeno u ovom slučaju, i koja radi odlično:

Sastavljanje mehaničkih dijelova

CNC.Mech.partsCNC kit sa mehanikom uglavnom stiže u dijelovima. Pod “mehanikom” mislim na sve dijelove stroja od aluminijske legure (Aluminij 6061), vijke, podloške, pogonske navojne osovine sa kugličnim ležajevima (tzv. “ball-screw”, SFU1204) i s auto-backlash korekcijom, kromirane klizne vodilice sa linearnim kugličnim ležajevima (tvrdoća 61HRC), te mali kompletić sa 3 imbus ključa, nekoliko čeličnih držača i odgovarajućim imbus vijcima.

Pored navedenog, ovaj “CNC mechanical kit” sadržavao je i nosače za Nema23 koračne motore od specijalne plastike, plastične “lance” za transport spojnih kabela od kontrolne elektronike do koračnih motora i sigurnosnih mikrosklopki, glavni motor koji nosi alat i napaja se naponom od 48V, snage 300W te pripadajućim koletom i maticom za pričvršćenje alata, kontroler za glavni motor koji regulira brzinu vrtnje istog te rigidne aluminijske spojnice koračnih motora sa pogonskim navojnim osovinama.

Zanimljivo je da kit ne stiže sa uputstvom za sastavljanje, niti sa bilo kakvom slikom, osim slikom spajanja napajanja i kontrolera za glavni motor. Ipak, na ebayu, od istog dobavaljača postoje slike složenog CNC stroja u nekoliko faza slaganja te slike snimljene iz nekoliko rakursa, što je velika pomoć kod slaganja stroja. Uglavnom, teško da se može pogriješiti, a glavni alat su imbus ključevi koji dolaze sa kitom i koji su izdržali sastavljanje kompletnog stroja, bez da su se “pokvarili”, što me oduševilo. Naime, imam loša iskustva s kineskim alatom, a ovo je bilo sasvim novo, pozitivno iskustvo.

DSCF3842Preporuka je da se krene sa sastavljanjem baze, tj. stranica koje nose X-os. Glavnu ulogu ovdje imaju dvije čeone stranice sa jednim centralnim provrtom za pogonsku navojnu osovinu sa kugličnim lezajevima i dva bočna provrta za kromirane klizne vodilice sa linearnim kugličnim ležajevima. Ove dvije kromirane vodilice osiguravaju paralelnost posmaka ploče X-osi na kojoj su kuglični ležajevi za vodilice i pogonsku navojnu osovinu, a koja na svojim “leđima” nosi bočne stranice Y-osi.

DSCF3846Kuglični ležajevi opremljeni su sa po jednom bradavicom za podmazivanje, što obavezno treba učiniti prije puštanja CNC stroja u pogon. Vodilice se na čeonim pločama X-osi fiksiraju imbus vijcima, a pogonska navojna osovina na jednoj strani fiksira se protukliznom maticom a na drugoj strani je osovina obrađena na promjer od 8mm za spoj sa rigidnom spojnicom tj. sa koračnim motorom. Na toj čeonoj ploči X-osi napravljena su i četiri provrta sa M5 navojima, za pričvršćenje Nema23 koračnih motora. Ove dvije čeone ploče fiksiraju se bočnim stranicama X-osi, na kojima se nalaze i četiri gumena nosača, na kojima leži cijeli stroj, i koji osiguravaju kakvu-takvu izolaciju od vibracija.

CNC.assembled.2Nakon što smo sastavili bazu na kojoj je X-os, na glavnu ploču X-osi najprije montiramo jednu bočnu stranicu Y-osi, koja također sadrži 3 glavna provrta za vodilice i pogonsku navojnu osovinu, (kao i X-os). Prije nego što pozicioniramo pogonsku navojnu osovinu i vodilice u jednu bočnu stranicu, potrebno je odrediti koja bočna stranica nosi Nema23 koračni motor, pa prema tome okrenuti pogonsku osovinu na taj bok. Također, potrebno je da na obje vodilice i pogonsku os navučemo kuglične ležajeve koji su već uprešani u aluminijski blok – nosač Z-osi. Pažljivo, ali silom koja je potrebna, pozicioniramo vodilice i pogonsku osovinu najprije u montiranu bočnu stranicu, a onda dodajemo i drugu bočnu stranicu i primjerenom silom utiskujemo kromirane vodilice i navojnu pogonsku os da sjednu u obje bočne stranice. Korekcije vršimo plastičnim čekićem, kako ne bi smo oštetili bilo koji dio našeg budućeg CNC stroja. Vodilice i navojnu pogonsku osovinu fiksiramo vijcima i protukliznom maticom, kao i na X-osi. Na slici je prikazan drugačiji pristup sastavljanja Y-osi, koje je također dobar, na način da se prvo složi kompletna Y-os, a tek onda montira na X-os.

Na Y-os montiraju se i dvije zaštite od tanjeg alu-profila, koje štite vodilice i pogonsku osovinu od prljavštine, koja bi ovdje mogla doći tijekom obrade materijala.

CNC stroj, Z-osZ-os je os s najmanjiom hodom, ali s najvećim početnim opterećenjem. Z-os je ujedno i nosač glavnog motora koji nosi i vrti obradni alat – glodalo, a ujedno i jedina os sa vertikalnim posmakom. Sastavlja se na isti na način kao i do sada sastavljene osi, a također se sastoji od dvije kromirane vodilice sa kugličnim ležajevima i jednom navojnom pogonskom osovinom sa kugličnim ležajevima i anti-backlash korekcijom. Na vrhu Z-osi nalazi se ploča koja nosi Nema23 koračni motor, koji je spojen rigidnom alu-spojnicom sa pogonskom osovinom Z-osi.

Napominjem da su sve tri osi opremljene kugličnim ležajevima sa auto-backlash korekcijom, što osigurava točnost ponavljanja i preciznost obrade gotovo na granici koja dijeli CNC hobby strojeve od polu-profi CNC strojeva.

Backlash-zracnostPojašnjenje “backlash” termina

Ovaj termin koristi se u CNC branši kao oznaka za zračnost u nekom od strojnih dijelova (uglavnom na pogonskim osovinama), koja ima direktni uticaj na preciznost obrade materijala. Backlash ili zračnost utvrđujemo i testiramo na nekoliko načina. Prvi i najjednostavniji je da jednom rukom uhvatimo pogonsku osovinu a drugom rukom ležaj u kojem se ona nalazi i povučemo osovinu naprijed-nazad u ležaju, nekoliko puta, kao da ju želimo isčupati iz ležaja. Ako pri tome u rukama osjetimo sitne udare tj. zračnost između navoja vretena pogonske osovine i navoja u ležaju, to je tzv. “backlash”, koji će degradirati točnost našeg stroja. Zanimljivo je da u programskoj potrpori Mach3 postoji mogućnost da se backlash softverski kompenzira. Da bi ga kompenzirali, moramo ga izmjeriti. Možemo ga izmjeriti komparatorom, na način da mjerimo za koliko će se translirati ploča koju pokreće pogonska osovina u zavisnosti od broja impulsa koje šaljemo koračnom motoru koji pokreće pogonsku osovinu. Podatak koji dobijemo mjerenjem unosimo u Mach3 programsku potporu i na taj način pokušavamo kompenzirati zračnost. Ovo u praksi znači da ćemo dosta vremena potrošiti testirajući cijeli sustav i modificirajući kompenzacijske vrijednosti. Da bih se na početku riješio ovog vječnog (i samo djelomično rješivog) tereta, cijeli sustav pogonskih osovina je zasnovan na anti-backlash kugličnim ležajevima a ne na kliznim navojnim ležajevima, kao kod istih CNC sustava sa “T” prefiksom, tj. sa trapezoidalnim pogonskim osovinama u trapezoidalnim kliznim ležajevima.

DSCF3832Nakon što montiramo sve tri osi, provjerimo još jednom da li su svi vijci na svojim mjestima, podmažemo vodilice i pogonske osovine, i pokušamo samo prstima vrtjeti pogonske osovine na sve tri osi, kako bi se osvjedočili da su pokretne uporabom i tako malih sila kao što je stisak prstiju. Ako je sve pokretno, onda smo napravili posao. Ako nije, podmažite još jednom vodilice i ležajeve, lagano raspustite vijke na vodilicama, ponovo pokrenite pristima pogonsku osovinu i ako sada ide sve kako treba, ponovo lagano pritegnite vijke na bočnim stranicama, koji fiksiraju vodilice. Na slici desno vidi se i osnovna horizontalna ploča, na kojoj se nalaze tzv. T-utori za pričvršćenje obradnog materijala. Ova ploča je također napravljena od aluminiija 6061 a pričvršćena je imbus vijcima za bazu X-osi i dodatno ukrućuje čitav stroj.

Uvod

CNC, akronim od Computer Numerical Control pojam je koji se veže uz računalno upravljanje strojevima za obradu drveta, metala, i drugih materijala od plastičnih masa, stakla itd. Za razliku od klasičnih glodalica, tokarilica i ostalih strojeva koji se koriste u obradi različitih materijala i kojima čovjek upravlja ručno, mijenjajući iz faze u fazu udaljenost alata od materijala koji se obrađuje, CNC strojem upravlja računalni program, kojeg je napisao čovjek, i kojim se automatizira obrada raznih materijala.

Postoje 2D i 3D obradni strojevi, sa 2, 3, 4 ili više pogonskih osi. Mi ćemo graditi 3D obradni stroj, sa 3 pogonske osi: X, Y i Z. Za one koji o CNC strojevima čitaju prvi puta, X-os je obično os sa najdužim hodom (duža strana stroja), Y-os je os na kraćoj strani stroja i obje su horizontalne, dok je Z-os obično u vertikalnom položaju u odnosu na radnu ploču stroja, i služi kao nosač glavnog motora za prihvat obradnog alata. Z-os se miče gore-dolje, ulazeći u obrađivani materijal određenom brzinom, vrtnjom i vrstom alata, ovisno o vrsti materijala koji se obrađuje.

CNC.backPrimjena

U svim granama današnje industrije, CNC strojevi su nezamjenjivi, i imaju veliku važnost. Svojom preciznošću i sposobnošću da nebrojeno puta ponove iste nizove obradnih postupaka zamjenjuju mnogo ljudi u proizvodnom procesu, skraćuju vrijeme obrade i pridonose smanjenju cijene finalnog proizvoda. Naravno, upravljanje CNC strojem zahtjeva i specijalizirane stručnjake, koji pored poznavanja tehnologije obrade materijala moraju biti i stručnjaci za CNC programsku potporu i programiranje CNC strojeva.

CNC stroj koji ćemo zajedno graditi, predstavlja minijaturnu kopiju velikih industrijskih CNC strojeva, i nije za profesionalnu uporabu, iako će preciznost našeg CNC stroja biti na granici profesionalnih zahtjeva. Naš CNC stroj biti će apsolutno za hobby primjenu, kao što je:

– izrada PCB prototipa (pločice sa tiskanim vodovima za hobby elektroniku)
– izrezivanje stranica za različite kutije, za različite prototipe elektroničkih uređaja
– bušenje rupa za razne elemente na prednjim pločama raznih prototipa elektroničkih uređaja
– graviranje natpisa na prednjim pločama raznih prototipa elektroničkih uređaja
– izrada dijelova za razne modele aviona, brodova i ostale modelarske zahtjeve
– ostala obrada raznih materijala za hobby namjenu.

CNC.sec.switchesPotrebna znanja za sastavljanje i korištenje CNC stroja

Moj prvi hobby CNC stroj kupio sam 2006. godine neispravan, na ebay-u. Znao sam da će mi biti potrebno dosta muke, truda i znanja da bih ga popravio i pokrenuo. Znanje koje sam tada imao obuhvaćalo je slijedeća područja:

– strojarstvo: razumijevanje rada strojnih dijelova i sila koje se javljaju u radu
– elektronika: razumijevanje srednje složenih elektroničkih sklopova te dijagnostika i popravak istih
– računalna tehnologija: instalacija operativnog sustava, instalacija CNC programske potpore, poznavanje barem osnova G-koda.
– razumijevanje tehnologije obrade raznih materijala

Ono što tada nisam znao, učio sam u hodu. Najviše sam morao raditi na upoznavanju tehnologije obrade raznih materijala i uporabe samog CNC stroja, vrste i namjene alata, angažirane snage motora, broja okretaja, brzine obrade materijala po osima itd. Puno je vremena utrošeno na čitanje stručne literature te primjene ili modifikacije novo naučene teorije u praksi. Sve se može, kad je čovjek motiviran, a tko sada ne odustane, taj je sigurno motiviran da izgradi ovakav (ili sličan) CNC stroj.

Kupiti novi CNC stroj ili graditi iz pojedinačnih dijelova?

Postoje najmanje tri motivacijske poluge, odlučujuće u donošenju odluke da li kupiti novi CNC stroj ili graditi svoj, iz pojedinačnih dijelova:

– financijski moment
– zadovoljstvo nakon završene gradnje stroja
– konfiguracija novog CNC stroja, koja je obično fiksna, i koja možda ne zadovoljava

Ako financijski moment nije bitan, a zadovoljstvo kupovinom nove “igračke” može nadomjestiti veliko zadovoljstvo samogradnje, onda ovdje možete prekinuti čitanje ovog članka. Vi ste kandidat za kupnju nove, gotove CNC igračke.

U mojem slučaju, sva tri momenta bila su važna i odlučujuća. Kad sam zbrojio dva i dva, bilo je jasno da ću financijski proći dosta jeftinije u konfiguraciji stroja koja daleko nadmašuje ponuđenu, a o zadovoljstvu što ću stroj graditi sam, da ne pričam.

NSR Fix in new GBCAT v1.31

NSR Fix in new GBCAT v1.31

NSR (Native Screen Ratio) program routine has the function to detect a graphic adapter, to calculate NSR and to set the appropriate ratio between some graphic elements, like an appropriate display of the analog S-meter unit simulation in GBCAT.

Thanks to mGBCAT_v1.3.ATI.Radeon.Bugy friend Wim PA3WT, who has found anomaly in GBCAT NSR program routine related to the ATI Mobility Radeon HD 5470 graphic adapter, I was able to solve this issue and today we have a new, fixed GBCAT version ready for DOWNLOAD.

GBCAT users who do not have described issue may proceed using GBCAT v1.3. without a need for GBCAT v1.31 download.

You may download Detect NSR, as stand-alone utility HERE.

Detect NSR Utility

Detect NSR Utility

This small but useful utility will help you to detect a native screen ratio (NSR) of your monitor and also to set a new graphic mode. Your monitor’s native screen ratio refers to DetectNSR.screenthe ratio between its width and height. For example, a 4:3 display produces an image that is more square, where a 16:9 ratio produces an image that is more rectangular in shape.

For example, the 16:9 NSR is sometimes referred to as 1.78:1, or simply 1.78. It is because 16 divided by 9 = 1.78 which is the same thing. A 1.78 screen is 1.78 units in width for every unit of height.

The computer display industry has been moving away from the 4:3 format in recent years, but 4:3 NSR displays are still in use.

If you have an LCD monitor, check your screen resolution. This helps to determine the clarity of on-screen images. It’s a good practice to set an LCD monitor to its native resolution. To see your monitor’s native resolution, check the last row in the “Available Modes from the main adapter” list in Detect NSR Utility. It is always the maximum resolution which your monitor can display.

With Detect NSR Utility you can also change your current graphic mode of your currently active graphic adpater. Select one of available graphic modes and click on “Set Mode” button. You will be warn with the following message box: “Would you like to change the Graphic adapter settings? Please, notice that a new settings will be done immediately. Choose ‘No’ to retain the current Graphic adapter settings.”

Detect NSR Utility is also a part of GBCAT – Computer Aided Transceiver, where it has the function to detect a graphic adapter, to calculate NSR and to set the appropriate ratio between some graphic elements, like an appropriate display of the analog S-meter unit simulation. Thanks to my friend Wim PA3WT, this utility is also tested on sometimes capricious ATI Mobility Radeon HD 5470 graphic adapter and works as expected.

Of course, for those who want to squeeze every ounce of speed, Timings are GBCAT_v1.3_Easy.Start.improvedstill configurable.
– Kenwood TS-590S bugfix: Sliders for the following controls now are initialized on GBCAT start: USB.Audio.out.Lvl, Acc2.AF-In.Lvl, Acc2.AF-Out.Lvl.
– According to many OM’s requests, default configuration value for Squelch now is 0 (no squelch).
– Kenwood TS-590S: Missed file for equalization feature now is packed with installation file.

 

GBCAT_v1.3_Band.Scope.on.HF.1-click.VFO.FQ.set– Band Scope improvements: Position mouse pointer and click on signal peak to stop the sweep and set the new VFO frequency (idea by Tim, KM4GUF (former KK4ZRZ)). Added FQ flag shown during band sweep. If you want to disable FQ flag, set signal index to 31.
– Added selection “Read Memory content at GBCAT start” in menu Rig/Kenwood: After the first GBCAT start, user is able to skip sometimes bored (but useful) Memory Channel content reading, or he can read it at GBCAT start as usual. If this selection is unchecked, „Set MC“ feature will not be loaded with the current memory channel data. Of course, it always can be loaded later.
– Added selection “TS-2000 Colored Buttons” in menu Rig/Kenwood: Use it if you like it.
– Added selection “Show info ‘Connected device is…’ at GBCAT start” in menu Rig/Kenwood: After the first GBCAT start, user is able to skip sometimes bored (but useful) info “Connected device is recognized as Kenwood…” etc. If you disable Memory channels content reading at GBCAT start, and this feature which also require user interaction, you may have GBCAT up and running within 8-15 seconds from the start, depending on how fast is your PC hardware, especially your hard drive unit.
GBCAT_v1.3_Graphic.Adapter– Added selection “Graphic Adapter settings” in menu Misc: It will show you info about the current graphic adapter settings as well as the NSR info required for an appropriate analog s-meter setting. Close it with the red “X” at the top right, if no changes are made.

 

 

New features:
GBCAT_v1.3_Analog.S.meter– The full configurable analog S-meter simulation (idea by Tim, KM4GUF (former KK4ZRZ)) with possibility to load User designed S-meter face plates.

 

– Telnet Client with 1-click set VFO FQ feature, selection between the regular terminal view and tabular view, internal band filtering, approx. QRB calculation in the real time, and many other useful features.

GBCAT_v1.3_Telnet.Client.1-click.FQ.set

There is also a few minor cosmetic changes (a button face plates redesign, the main FQ display without a phantom backgrounds, etc), as well as a few bug fixes which I forgot to write down, because writing manual is a time-consuming process for me. I hope that GBCAT users are power users who will know to find some undocumented changes. If anyone has a good will to update GBCAT manual and thus join to GBCAT development process, also to contribute to the HAM community on that way, please do not hesitate to contact me. GBCAT is free of charge, so any form of your help is welcome.

New GBCAT v1.3 will be available for download very soon. Wanted a few Windows 8.1 testers. If interested, Contact me at emu.9a2gb(at)gmail.com

Make GBCAT start easier

GBCAT_v1.3_SSI_TelnetHi OCs, here are a few hints which GBCAT start can make easier:

Beside a COM port settings, which are different for almost every brand and RIG model, GBCAT has implemented a two important timing parameters related to a successfull communication between your RIG and GBCAT. These two parameters has been introduced to achieve the maximum communication performance:

– Menu “COM”, item: “TXD Line Polling Delay“, default value = 10
– Menu “RIG”, item: “RIG Polling Delay (ms)“, default value = 350

These two timing parameters directly affect the communication between your RIG and GBCAT. A default values off these parameters are written in “GBCAT.cfg”, and represents a compromise values for most RIG brands and models. However, there are always differences, even among devices of the same manufacturer and the same model. Compromise is not always the best possible solution, so in some cases there may be a need for playing with these two timing parameters, to achieve the maximum communication performance.

The meaning of the parameters and rules of use:

RIG Polling Delay (in milliseconds), is a required time while GBCAT wait on response from your RIG. If the communication speed is higher, the response time is shorter, so the RIG Polling Delay value has to be lower.

TXD Line Polling Delay acts like a divider for the RIG Polling Delay value. The result is a value in milliseconds, which represents a time required for GBCAT data processing until a new RIG enquiry is generated. If the communication speed is higher, GBCAT processing time need to be shorter. According to that, the TXD Line Polling Delay value has to be higher.

Please, have a notice that these default values are tested on a few different RIG brands and models, and represents a recommended values for communication speed of 38400 bps. If you are using a speed lower than 38400 bps, please correct a default values for these timing parameters, according to rules of use.

Whether GBCAT could work without these additional timing parameters? Of course it could work without it, but what we wanted to achieve was not a snail’s crawling but cat’s hopping. In other words, we wanted to achieve effective RIG control and ergonomic RIG response at the same time. Therefore, if you want control your RIG better than mediocrity, please play with timing parameters to gain the CAT’s hopping. If you need any other hint or help, please, do not hesitate to contact GBCAT support, after you read GBCAT help file.

Aside

What’s New in GBCAT v1.2?

The greatest news in this version is support for Kenwood TS-590S transceiver. GBCAT support about 95% of all capabilities of this excellent radio, so give it a try!

Also, a few bugs are fixed:

– Fixed bug (TS-2000, button “PWR”): after Power Off/On, Audio and Squelch are initialized again.
– Fixed bug (TS-2000): After GSCAN feature turned off, the following buttons unfortunately remained disabled: APO, FSK.R, iT2M, CALL, 2CALL.
– Fixed bug (TS-2000): TX and RX frequency labels are at correct position now.
– Fixed bug (TS-2000): Kenwood specific buttons MULTI/CH 1 step Up/Down now are shown correctly after NUMF/Set FQ features are performed
– Fixed bug (TS-2000): Sub receiver may stay turned on while GSCAN is activated. Control will be switched to the Main receiver.
– Fixed bug (TS-2000): While switching CTRL from Main to Sub and back, Squelch value changes while slider position stays unchanged.
– Fixed bug (TS-2000): Shown TX frequency now includes calculated repeater shift.
– Fixed bug (TS-2000): After switching VFO-A/VFO-B, the Power slider for the current Band now shows band power correctly.

A few minor bugs are also fixed, as well as a few minor cosmetic changes are applied. Please note that there has been a revision and extension of the GBCAT.CFG configuration file, so the old configuration file can’t be used with the new version of GBCAT.

New features and improvements:

– Improved, optimized, 5x faster GSCAN (TS-2000, TS-590S).
– Improved conventional memory operations (TS-2000, TS-590S).
– Improved COM2IP Redirector and IP2COM Server.
– Added feature (for all supported RIGs): GBCAT Easy Start.
– Added feature (TS-2000): Kenwood TS-2000 DTMF Memory Manager (Button DT).
– Added feature (TS-2000): User mode Equalization for both RX and TX modes (with installed filters).
– Added feature (Kenwood): Signal strength indicator (slightly precise than S-meter, 0-30, step 4db).
– Added feature (Kenwood): Memory keying (Button MK).
– Added feature (for all supported RIGs): The simple Parrot feature, “P” button (near “PTT” button).

WWAN Speed from Island of Vir.HR.EU

WWAN Speed from Island of Vir.HR.EU

For all those who are planning to come to our beautiful island of Vir, and for those who already enjoy under the sun on the island of Vir and don’t want to give up the benefits of the Internet, we measured the average speed of HSPA connection from the island of Vir. Measurement micro location: Velika Slatina bay, north side of the island of Vir, (view on the island of Pag, Povljana place).

The subjective impression is much better than numbers of the measured speed. The real internet speed is much faster then required for the standard mail exchange and allows even web pages mastering.

Provider: Tomato (Vip.HR)
Connection mode: HSDPA
DL speed: 1.84 Mbps
UL Speed: 1.4 Mbps
Ping: 14 msWWAN.Speed.from.IslandOfVir.HR

Here are the real speed ranges of the various mobile wireless strandards commonly used today:

GSM (Global System for Mobile Communications) 2G: 9.6Kbps
GPRS (General packet radio services) 2.5G: 35Kbps to 171kbps
EDGE (Enhanced Data rates for GSM Evolution) 2.75G: 120Kbps to 384Kbps
UMTS (Universal Mobile Telecommunications System) 3G: 384Kbps to 2Mbps
HSPA (software upgrade to UMTS, theoretical 42Mbps) 3.5G: 600Kbps to 10Mbps, averages 1-3Mbps
LTE 4G (Long Term Evolution, theoretical 100Mbps): 3Mbps to 10Mbps average, 20Mbps+ peak download speeds.

Previous testing

Vir is an island on the Croatian coast of Adriatic sea located north of Zadar. Vir has a very good connectivity to the mainland via a road bridge.

GBCAT goes to EQwood

GBCAT goes to GBCAT.v1.2.UserModeEQEQwood!

From version v1.2, GBCAT will be able to deal with the User mode Equalization. This new feature will be available for both the RX and TX modes for the Kenwood TS-2000. As you know, the TS-2000 has a few factory predefined EQ settings and User EQ mode as the last choice in the Menu #20 (RX equalizer) and in the Menu #21 (TX equalizer).

By default, you may set your TS-2000 to any factory predefined EQ setting, but that’s all folks. Unfortunately, the Kenwood engineers didn’t left the possibility to the user to self-create the EQ filters for a specific needs. It is the Kenwood’s secret, and it is possible to stay the unexposed for a while.

The GBCAT Development Team didn’t revealed that mystery, we just find not exactly a comfortable but usable way to create a new EQ filters for the User EQ mode. In the new GBCAT version, a whole bunch of 21 predefined EQ filters will be available to the GBCAT users, plus a few EQ filters made by other radio amateurs. Of course, all credits for the EQ filters collected from the other sources goes to their authors, which will be honored by mentioning of their Call signs.

The User mode EQ (DSP) function of the TS-2000 can be used in the form of four Filter types:

1. LPF = Low Pass Filter
2. HPF = High Pass Filter
3. BPF = Band Pass Filter
4. BEF = Band Edge Filter (band-stop filter or band-rejection filter or Notch filter)

You can select any of predefined filter type and send it to the RIG immediately. Every filter may be used for the RX and for the TX mode. The new EQ adjustment will not affect any of the factory predefined filters, just and only the USER MODE EQ filter.

If you have a need for the specific filter currently not covered by GBCAT and it’s type is mentioned above, send the needed specific filter specifications to the support mail address.

We will try to create a new filter according to your specifications and include it in the next GBCAT version, using your CALLSIGN as the filter name.

As we have already published so far, GBCAT v1.2 will offer also a support for the Kenwood TS-590S. Take a look at it’s Equalizer screen.

Test: Tengda S4

Aside

Tengda_S4_1Test: Tengda S4 

U moru različitih kineskih pametnih telefona pogonjenih Android operativnim sustavom, od kojih su pola izgledom kopije nekih vrlo poznatih brandova, pronađe se i pokoji model koji uopće nije loš. Jedan od takvih je i “Tengda S4”, za koji kažu da je pokušaj kopije poznatog branda i modela “Samsung Galaxy S4”. U ovom testu nećemo dokazivati koliko je kopija uspjela i u čemu se razlikuje od originala, već ćemo se usredotočiti na test konkretnog primjerka Tengde.

Sadržak kutije/kompleta:

Tengda S4 dolazi u relativno maloj, skromnoj kartonskoj kutiji, koja možda i ne bi izdržala da netko slučajno sjedne na nju, ali stigla je iz Kine bez i jednog znaka oštećenja na kutiji. Komplet sadrži:
– Tengda S4 pametni telefon s Android operativnim sustavom i ekranskom zaštitom
– 2 Li-Ion baterije kapaciteta 2500mAh
– Punjač (100-230V na 5V/700mA) s USB priključkom
– USB kabel za punjenje ili prebacivanje podataka na PC računalo
– uputstvo na engleskom jeziku
– dodatna zaštitna folija za ekran
– slušalice s višepolnim 3.5mm priključkom i zaštitnim spužvicama

Tengda_S4Vanjski izgled i kvaliteta kučišta

Dimenzije Tengde S4 su nešto veće od dimenzija Samsunga Galaxy S4 (141x71x10 prema 136.6×69.8×7.9 mm) i izgledom podsjeća na svog slavnog prethodnika. Ako se oba telefona postave jedan kraj drugog, naoko nije vidljivo zašto je Tengda dvostruka jeftinija od Samsunga. Tek kad uhvatite Tengdu u ruke, i pokušate primijeniti laganu frikciju na kučište, Tengda jedva primjetno škripi i pucka, dok kod Samsunga nismo zamijetil istu pojavu. Kučište Tengde je plastično s metalnim okvirom, prilično dobro oblikovano, čak i završna obrada nije loša. Pozadina je od crne sjajne plastike, na kojoj se vidi apsolutno svaki otisak netom opranih ruku. Naravno, ekran nije zaštićen “gorilla-glass” staklom, jer to košta, a mi želimo jeftinu radnu snagu.

Tengda_S4_DeviceInfoTengda – jeftina “radna snaga”

Tengda S4 je dvostruko jeftinija od Samsung Galaxy S4, no, kad se malo bolje pogledaju njene specifikacije, to i nije tako loše:

Frekventni opsezi: 2G: GSM 850/900/1800/1900MHz, 3G: WCDMA 850/2100MHz
Sim: Dual SIM Card, Dual Standby (jedan micro sim card + jedan standradni sim)
OS: Android 4.2.1
CPU MTK6589T, Cortex A7 quad core, 1.5GHz;
GPU: PowerVR SGX 544
ROM: 32GB (standardno, na osnovnoj ploči)
RAM: 2GB  (standardno, na osnovnoj ploči)
Ekran: veličina 5.0 inča (dijagonala 127 mm), kapacitivni IPS ekran
Razlučljivost: 1920 x 1080 piksela (FHD), 16000K boja.

Tengda S4 će vas ipak razveseliti nekim vrlo visoko postavljenim standardima, kao što su 2GB RAM-a i GBMB ROM-a koji su ugrađeni tvornički. Vjerujem da ste već iskusili kako Andriod uređaji sa svega 1MB RAM-a mogu iritirati nekim povremenim lagom. Razvojni inžinjeri Tengde očito su imali financijere široke ruke, jer se kombinacija 2GB/32GB ne susreće ni u gornjoj srednoj klasi android telefona, već samo u visokoj klasi. Nešto malo manje od 32GB skladišnog prostora, koliko preostane nakon podizanja sustava, svakako će biti dovoljno i za većinu potreba, a ako vam to ne bude dosta, mođete dodati SD memoriju sa dodatnih 16GB, i uživati u prostranom skladišnom prostoru.

Multimedijalne sposobnosti

Ako ste od onih koji znaju što je dobra 8 Mpix kamera i bili ste razočarani ponekim kineskim telefonima koji se kunu u tu rezoluciju, onda će vas sigurno “obradovati” podatak o tome da ni Tengda nije imuna na razbacivanje s Mpixelima, jer na njoj stoji podatak o 18 Mpix kameri, na pozadini telefona. Nema veze, čak nije ni bitno da li je to stvarno tako ili je u  pitanju samo četvrtina deklarirane rezolucije, ali ono što nam se svidjelo svakako je to da Tengdina kamera ima odličan auto fokus i da radi upotrebljive fotografije i u tamnijim uvjetima fotografiranja, što je odlika boljih i skupljijih telefona. Pored kamere nalazi se i bljeskalica, tj. LED izvor bijelog svjetla, koji odlično radi svoj posao. Kamera daje sve od sebe, radi to na prihvatljiv način i opraštamo joj natpis “18 Mpix Full HD”.

Zvuk na Tengdi je odličan, vrlo malo izobličava i kod najglasnije postavke, bogat je i visokim i dubokim tonovima, što se dodatno da poboljšati postavkom u operativnom sustavu. Da li tko sluša FM radio na svom telefonu, ne znamo, (nismo od tih), ali kad je već tu, isprobali smo ga i dajemo vrlo dobru ocjenu. Radio je dosta visoke osjetljivosti, pa na mjestu gdje kućni Kenwood ponekad zašušti, Tengdin FM radio odavao je puno bolji dojam, hvatao signale čak i iz susjedne dežele, što je imajući u vidu da mu kao antena služi žica od slušalica, odličan rezultat. Zvuk je odličan, bogatstvo tonova širokog spektra, za što su zaslužne i vrlo dobre slušalice iz kompleta.

Tengda_S4_AppsGSM telefon i 3G modem

Isprobali smo funkcije (3G podatkovni promet i GSM telefoniranje) na mrežama dva nacionalna mobilna operatera. Ništa bolje ili lošije od sličnih telefona, osim što je zvuk dosta kvalitetan i prirodan. Podatkovna veza, zbog blizine bazne postaje, bila je stabilna pa na ovaj dio niti imamo primjedbe, ali nema ni neke euforije.

Bluetooth

Bluetooth povezivanje isprobali smo pomoću Jabbra BT 205 bežične slušalice za telefon, koja se uspješno spaja na široku lepezu telefona, tableta i računala. Spajanje na tablet je prošlo jednostavno i brzo, nakon što smo oba uređaja stavili u mod traženja. Jabbra odlično radi sa Tengdom, siguran domet u kojem nema prekida je čak preko 4 metra.

GPS

Globalna geolokacija s test pozicije radi jednako dobro kao i samostalni GPS uređaj, a pripomognuta je takozvanim A-GPS sustavom, koji omogućuje brži prvi start, služeći se podacima o vašoj poziciji, ako ste mu to omogućili u postavkama tableta. Prvi start je unutar 7-9 minuta a pomognuti je unutar 2 minute od starta.

Baterija

U kompletu dolaze dvije baterije od po 2500mAh, što je nekakva zlatna sredina za telefone te klase. Bili bi smo zadovoljniji samo s jednom baterijom od 3000 mAh, jer ako računate na izmjenu istrošene baterije pričuvnom, svaki puta kada vam to zatreba, onda računajte i na potrebu skore izmjene stražnjeg poklopca telefona, jer nam se čini da će se sustav zatvaranja vrlo brzo istrošiti (plastika). Tengda je izdržala našu cjelodnevnu maltretažu s uključenim 3G, WiFi, i sa ekranom na 60% bez nekih problema, a punjenje je trajalo nešto preko 3h. Solidno. Čekanje na poziv deklarirano je u trajanju od 2-3 dana, ali to nismo za sada isprobali. Kontaktirajte nas za detaljnije podatke.

Sažetak: procesna moć

Sve što smo isprobali, radilo je iznad očekivanja za što se pobrinuo MTK6589T, Cortex A7 quad core na 1.5 GHz, koji osigurava da se sve odvija glatko i bez čekanja, a u pomoć mu je priskakao grafički podsustav s PowerVR SGX 544 procesorom. AnTuTu v 4.1 benchmark test daje podatak od 14927 bodova za Tengdu S4. Za usporedbu, Samsung Galaxy S4 na istom test dobija 27435 bodova, dakle nema riječi ni o kakvoj kopiji. Zanimljivo je da je Tengda S4 bolja u RAM operacijama (1401 prema 1387), dok je u Storage I/O neznatno slabija od slavnog usporednika Samsunga (1007 prema 1272). Tengda S4 po rezultatima testa dalkeko je bolja od Samsung Galaxy S2 (14927 prema 10576), a usporedljiva sa HTC One X (14927 prema 15756).

Radna memorija od 2GB će postati standard za pametne telefone ove kategorije, jednako kao i interni prostor za skladištenje podataka od 32MB. IPS zaslon je visoke razlučljivosti, i vidljiv je iz svih kuteva gledanja. Zvuk je odličan, jednako kao i ugrađeni FM radio. Ovaj telefon, može se nabaviti po cijeni od cca 280 USD na kineskom tržištu i predstavlja za sada adekvatnu vrijednost za spomenuti iznos, jer po svojim značajkama nadmašuje čak i 50% skuplje pametne telefone drugih proizvođača.

GBCAT v0.9b9, “The Last Beta”

Aside

GBCAT_v0.9b9_TS-2000.screenshotGBCAT v0.9b9, “The Last Beta”

Members of the GBCAT Beta Test team can download and test GBCAT v0.9b9, (the last beta version before the first public release of GBCAT) here:We hope that almost a month, how much is left up to the first public release, will be enough for detecting any previously undiscovered bugs. The first public GBCAT release is planed for December the 25th 2013, as a gift under the GBCAT_v0.9b9_FT-817.screenshotChristmas tree.

GBCAT development has been ongoing for two years, and takes all of the author’s free time; nevertheless, GBCAT is free and will be free of charge.

GBCAT is still in development. Any suggestion for the GBCAT improvement (as well as bug report) will be considered and implemented (or fixed) in one of the future GBCAT versions, if possible.

The images above shows screenshots taken while the GBCAT controlled the following transceivers: Kenwood TS-2000(tm) and Yaesu FT-817(tm). Larger images can be found HERE.

GBCAT v0.9b9, “The Last Beta”

Članovi GBCAT Beta Test tima mogu preuzeti i testirati GBCAT v0.9b9, zadnju beta inačicu prije prve javne GBCAT objave ovdje:Nadamo se da će gotovo mjesec dana, koliko je preostalo do prve javne objave, biti dovoljno da pronadjemo sve do sada neotkrivene bugove. Prvu javnu GBCAT publikaciju planiramo za 25.12.2013. godine, kao poklon pod božićnu jelku.

Razvoj ovog softvera trajao je dvije godine, a koliko je neprospavanih noći i slobodnih sati utrošeno to zna samo moja voljena obitelj, koja me podržala kao i uvijek, u ovakvim projektima. Bez obzira na to, GBCAT je besplatan, i ostati će besplatan.

Razvoj GBCAT-a nije gotov, ali je ovom inačicom zaokružena jedna funkcionalna cjelina, koja po mišljenju članova GBCAT Beta Test tima, zaslužuje javnu objavu.

Slike iznad prikazuju izgled GBCAT ekrana za vrijeme kontrole slijedećih primopredajnika: Kenwood TS-2000(tm) i Yaesu FT-817(tm). Veće slike pogledajte OVDJE.

GBCAT v0.9b7 - RIG-Kenwood specific-Kenwood TS-2000 MenuWhat’s new in GBCAT v0.9b7? (all related to Kenwood TS-2000)

Updated GBCAT_DocEN.doc, help file on English language (English spelling and grammar managed by Jim, K5LAD).
Bug fix: Problem in Com to IP Redirector with connection to TCP/IP addresses, other than hardcoded, is resolved. COM2IP.exe is the integral part of GBCAT and COM2IP_v09b7.msi installation package. It is required for the RIG remote operation, over the wireless or wired IP network. You may find it in the GBCAT installation directory. I noticed a described problem after I had changed the IP address and port on one of the computers on my home network. Now, you may try to redirect the COM port of your remote computers again.
Bug fix (thanks to Jim K5LAD): Problem in DX Summit Menu selection, with Set New FQ button, imported in v0.9b6, is resolved. Button Exit is added to simplify exit from DX Summit and return to the GBCAT main module.

GSCAN
GSCAN is a software featured Scan. It was developed (and tested) for Yaesu FT-8×7 and for Icom IC-706MKIIG. Because the Kenwood TS-2000 has many SCAN possibilities, I decided to reprogram this feature also for TS-2000 and enable it in the XCS-A group, under the GSCAN button. This feature is related to menu RIG, Edit GSCAN Table option. You may edit the GSCAN Table and save the new scan settings only while the GSCAN feature is disabled.

SCAN (Button)
Scan is a useful function for hands-off monitoring of your favorite frequencies. The SCAN button has start-stop functions: 1st click will start the Scan function, the 2nd click will stop the Scan function. It is so-called Normal, VFO Scan.

SCAN Mode (Slider)
Related to the Scan button, the Scan Mode slider has the same functions plus a few additional modes: Off, Scan, MHz, Visual, Tone, CTCSS and DCS Scan. If you start Scan by the Scan Mode slider, you may stop it also by one mouse click on the SCAN button. Please, note that not all of the Scan Modes information may be shown on the GBCAT screen, as they are shown on the RIG, because of lack of appropriate CAT commands.

PS.SLO (Button)
Program Scan partially slowed (ON/OFF). You can specify a maximum of 5 frequency points for each memory channel from 290 to 299 so that the Program Scan slows down the scanning speed. To specify the slow down frequency points, first program the start and end frequencies into a memory channel (290 ~ 299) {Owner Manual, page 67}.

PS.H5 (Button)
This function stops Program Scan for approximately 5 seconds, then resumes Scan when you jump to the desired frequency by turning the Tuning control or the MULTI/ CH control, or by pressing Mic [UP]/ [DWN].

PS.RM (Button)
Scan resume method function. The default is a time-operated mode. The transceiver stops scanning at the frequency (or memory channel) where a signal is detected. It then continues scanning according to which resume mode you have selected. You can choose one of the following modes:
• Time-Operated mode
The transceiver remains on a busy frequency (or memory channel) for approximately 6 seconds, then continues to scan, even if the signal is still present.
• Carrier-Operated mode
The transceiver remains on the busy frequency (or memory channel) until the signal drops out. There is a 2 second delay between signal dropout and scan resumption.

GBCAT v0.9b7 - Kenwood TS-2000 MenuKenwood TS-2000 Menu
Many functions on TS2K transceiver are selected or configured via a software-controlled Menu, rather than through the physical controls of the transceiver. Once familiar with the Menu system, you will appreciate the versatility it offers. You can customize the various timings, settings, and programming functions on this transceiver to meet your needs without using many controls and switches.

GBCAT v0.9b7 - Simple PR TerminalSimple Packet Radio Terminal
A packet is a group of bits (binary digits) structured and standardized that has contained within it the addressing information, message, error-checking and control information. The information is organized into a frame, i.e., a set-sized template for sending information. The Amateur X.25 protocol is the manner used to send frames. Both the sending and receiving TNC is programmed to encode into frames to be sent, and decode received frames.

If you are using GBCAT as CAT controller for your TS-2000 transceiver, it is assumed that you already have connected the serial interface of your computer with the COM-connector of the TS-2000. You still must adjust a couple of values in the menu of the TS-2000. Enter Menu #46 and choose the sub band as the data band. “TNC” sign should be seen in the right area of the Sub receiver display. Enter Menu #47 and choose 1200bps (or appropriate bps) as the transfer rate between the TNC (transceiver) and the ISS-PMS. Enter Menu #48 and choose DCD-sense as TNC-Band. The DCD is a method with which one impedes the internal TNC to send data if straight data traffic takes place on the QRG. Check for the transmission rate between PC and TNC (TS-2000) as the last, under Menu #56. It is 9600 baud, by default. Put the “Packet Operation” to “ON” under Menu #55. The letters “PKT” appear in the display above on the right. At the same time, you’ve started Simple Packet Radio Terminal, and you are ready to receive packets on your QRG. If you like to receive all or a different types of PR frames, use the following TNC commands: MCON (monitor other frames while connected), MALL (monitor connected and unconnected -unproto- frames), MCOM (monitor only data or all frames). Once you set all necessary PR settings, you may run Simple Packet Radio Terminal from GBCAT XCS-A module.

While you are in PR mode, the TS-2000 settings can’t be changed by GBCAT.

Simple Packet Radio Terminal is tested with Kenwood TS-2000 in two working conditions: Direct COM access and over the Home TCP/IP LAN (using COM2IP Redirector, the integral part of GBCAT installation package), and it works as expected in a both working conditions. It will be also available for the other rigs in the future.
