Al, check the electret condenser mic element soldering. Polarity is important.

Just finished wiring my bitx40.

Draws ~350ma with PTT, but no change at all when yelling or whistling into mic. (Dummy load present at all times, so don't suspect final blown.)

I see lots of discussion around this issue, but would appreciate advice on how to troubleshoot.
