Problem solved. Yamaha Mic out has stereo plug, AD-1-YM microphone plug is designed for mono in. So I used a stereo to mono adapter between the CM-500 headset male plug and the AD-1-YM audio female plug

Trying to get it to work with my Yamaha CM-500 headset. The Heil PTT switch works fine in the other half of the AD-1-YM to trigger the transmit, but no sign of audio output from the CM-500 going into the AD-1-YM..the MIC level remains at -30 dBM with no sign of movement. So I try the Yaesu FT817 hand microphone with its own connector to Flex 3000, works perfectly. I see MIC levels peaking around -2 dBM. So it's not the Flex radio or the SDR settings. I now try a Plantronics headset with the AD-1-YM connector. Again, no sign of audio output. When I tried the AD-1-YM and the Yamaha CM-500 hooked to my FT817ND QRP radio, no audio out. It would not trigger the VOX on the FT817ND. As soon as I hooked up my FT817ND hand microphone to the FT817ND rig, it triggered the VOX on the FT817ND rig just fine. It seems unusual that the AD-1-YM plug would be bad. And I find it unlikely that the wiring would be incorrect. But these are the only two options: (1) A bad connector (2) Incorrect wiring configuration Is anyone else using the AD-1-YM connector with a Flex 3000? This would help to eliminate Door #2.
