Transmitter working
I played with wiring mics up to the radio a little more, not having much luck. Seems the Cobra power mic had the best response.
I got the radio working today. I first tried it on 40 meters AM. Band conditions were bad, so I switched to 80 meters. It sounded decent on my SDR, and my friend was able to copy me. However the receive on AM wasn't very good. I noticed that the narrow CW filter appears to be operating in the AM mode. So audio was really pinched.
I started to see the proper IC movement. When I switched over to ALC, it was indicating as it should. This was the first time I've seen the ALC action working in SSB mode.
I proceeded to LSB and was able to have a good QSO with my friend on 75 Meters LSB.
I played with the mic gain and power mic gain, and it was sounding real good. Setting 6 on the mic and setting 8 on the radio.
I'll call that a success. Looks like I'm getting at least 100 watts SSB out of it. I'll need to check it on an accurate PEP watt meter though...
