H Mike, resonant antenna 1:1 and same with dummy load. thanks for the reply. This is a fully completed model. Not the kit.. Not sure if it's worth revisiting the bias settings or if there is just modulation of the mic input somehow.. The 2 tone test works fine without distortion I guess since it is generated by the pi in digital mode to the codec. But the mic input is being distorted. I will dig into this at some point soon, but just need to gather information before doing anything. I love this radio, in fact if I can get this problem resolved it will be my main rig. (also have ten tec omni VII, IC-7300 and ubitx rev 5 with ssm2167 compression that makes it an amazing rig).?
