Not even the slightest indication on a 5 watt scale meter. The radio indicates that it is modulating, and it can be monitored on another radio ( I can hear the audio). I was running SSTV when it happened, or just before it happened. Ater testing SSTV transmit and receive, I disconnected everything to try to neaten up the wiring and all, and when I got everything buttoned back up, I went to transmit SSB voice with my mic and discovered that all of a sudden I have almost no power! Any ideas? I wonder if I put too much audio from the soundcard into the microphone circuit... Could that possibly start a chain of events that could lead to this failure? Thanks for any thoughts or advice at this point.
