| IC-910 zJaponi cxy warto? |
| To radio ma ambiwalentne oceny. Absolutnie nie powinno się go używać z dodatkowym PA. Link do artykułu QST z oceną tego transiwera:http://hamradio.online.ru/ftp2/ic910h.pdf Dla wygody wyekstrahowałem interesujący fragment: IC-910H as Contest Transceiver If the ’910H performs well for terrestrial weak-signal and satellite work, would it perform just as well during a contest? If your contesting interest is more than casual, this transceiver may disappoint. In fairness, however, the IC-910H is not designed to be a competitive contest radio, and it would be unreasonable to compare it to, say, a VHF/UHF contest station based on high-performance transverters. The dynamic range performance on 2 meters and 70 centimeters wasn’t adequate to deal with numerous nearby signals. I set up a contest simulation with a couple of stations and it quickly became clear that the ’910H wasn’t up to the task of sorting through the chaos (even with judicious use of the IF SHIFT control and RF attenuator). It is important to note that our Lab tests revealed that the IC-910H generated a substantial amount of phase noise on all bands. In casual applications, this would not be a problem. Unlike HF phase noise, these signals would not travel very far. However, if you were using the IC-910H in a multioperator contest environment, the transceiver has the potential to create a fair amount of interference to the other radios, depending on the bands and frequencies in use. ------------- W uzupełnieniu, porównanie i ocena różnego sprzętu na ukfy: https://www.df9ic.de/tech/trxtest/trxtest.html Tamże taki passus: ... IC910H have a very poor LO design. They are well suited for FM repeater operation connected to an indoor HB9CV antenna. Other use should be prohibited. IMO, to ostatnie zdanie nie wygląda na żart. Korzystałem z IC910 pracując w zawodach na dwójce i w mojej ocenie jest on do tego celu nieprzydatny. Jeżeli masz możliwość i środki na zakup czegoś nowszego, nie kupuj tego ICOM'a |
