If I take the headset off, enable the speaker and transmit through the handheld microphone, there's a feedback noise. Any way around this? I've tried turning the volume down but it didn't help much.

Shouldn't the cockpit speaker have zero sidetone? Sidetone is designed to replace the natural hearing of your own voice that is blocked by the headset, so you shouldn't need it with open ears. Seems like enabling cabin speaker should shut off sidetone and that is not happening in this case. Mike C.

I believe that is correct for Garmin audio panels, but the Baker panels in the Avanti I (and almost all jets from the '60s thru the early 2000s) do have speaker sidetone. I think the newer Avanti II Evo has Becker digital panels, so it should be adjustable.
The other possibility is that the mic has a blocked noise cancelling port. That will cause it to pick up more ambient noise including speaker sidetone.
