Hi Guys,
I've got a question regarding SSB audio troubleshooting. I mainly use the K2 as my "CW rig". But I was recently checking it out on SSB. On 20m USB, I was getting a report that my audio sounded distorted. I adjusted the transmit filter OP1 to adjust the BFO setting, which seemed to improve the audio on USB quite a lot. But on 40m LSB, the audio is also sounding distorted and although I tried adjusting the BFO I wasn't able to improve it all that much. Any advice on how to troubleshoot this, and also could there be some other problem accounting for this (e.g. grounding issue, bad mic connector, etc)? I suspect it has something to do with the BFO setting and I just have to keep experimenting with different settings, but I could be wrong. I'm using the Heil handmic with Yaesu wiring.
Note that the firmware rev is 1.04d, which I understand is very old. This rig is the 15w version, and has the internal battery, SSB, noise blanker, and auto tuner options.
Thanks in advance for your advice.
