Icom OPC-478 Programming Cable

Hello all,

I've had the Icom IC-2200 2m transceiver for the past few month for my base unit. I haven't been using it for a long while as I seldom QSO when I'm home... too many other things to do... Lately several new repeaters have been on the scene and as always... read as being lazy... I take not effort to update the IC-2200 frequencies.

Lucky for me, there's another station who got nothing to do other than amateur radio and, better still, he is also using the IC-2200... read as cloning time... Though the IC-2200 allow cloning using a simple stereo cable, I wanted to edit some of the frequencies before loading it on my unit... the hunt for suitable arsenal begins...

To do what I wanted to do... three things are needed... 1) The Icom OPC-478 programming cable, 2) The right software, and 3) a USB to RS232 convertor since my PC doesn't have built in serial port. Found the circuit for OPC-478 equivalent on the net so I got that done. Found the right software... somehow :-) I also got the USB to RS232 convertor

I'm ready right? Nope, as it turns out the USB to RS232 convertor had some compatibility problems... It was detected by my OS but fail to work with the OPC-478... Lucky, I had another converter (another brand) lying around and that unit worked... Conclusion, get USB to RS232 converter that uses the FTDI chip... it seems to be more 'compatible'... how to tell the different? You can't... most packaging do not specify the chip used... :-( Just try your luck... btw, the one that worked was molded with dark grey plastics... the one that does not work was molded using blue plastics... don't know if that helps...
