KComm does JUMA

I have just finished adding support for the JUMA TRX2 transceiver to my logging program KComm. This will be available in the next version, 1.6, which will probably be released in the next couple of weeks. It really needs more testing to be sure everything is working as it should, as there are always issues that aren't immediately noticeable or problems that only occur when you do something you don't do very often.

I ordered a new USB to serial port adapter at the weekend after I experienced problems communicating with the JUMA using the ones I had. The new adapter arrived today. This one uses the FTDI chipset, rather than the Prolific chipset used by the other two adapters. I can report that this adapter works perfectly with the JUMA and both KComm and Fldigi. Unfortunately I notice a slight increase in noise in the JUMA receiver when the computer is connected to the radio using this adapter. I didn't check for this when using the other adapter or the real serial port, so I'm not sure at this point if it is an issue with this particular adapter or not.

Darned computers, sometimes I think they are really more trouble than they are worth!
