Jerry, thanks for the tips. I was able to adjust RV1 and see 100mA with the key down and no audio input. However, I do not see the 1A current when shouting/whistling into the mic. My "power meter" is a QRP Labs dummy load with pinouts for the voltage across the resistors (and a formula for calculating watts). I still only see 3V peak across the load which is very low (should be like 20V or more I think).

How can I further inspect the audio chain to see where my signal is dropping off?
