Maestro C and headset?

Hp1XT

Setting up AntLion mic and headset. Plugged mic into headset port and headphones into speaker jack. Connecting to RHR, hear the radio fine but unable to xmit even whilst selecting MOX. The main menu shows Maestro Bias +20 and unable to change to lower +5. How do I do that and is there a VOX that can be selected?

Tom: I don't have any experience using the AntLion mic with a Maestro, and using that combo with RHR probably adds another layer of complexity.

But I use an AntLion directly into my 6600 and found that I needed to wire up an adapter cable to make it work. The wiring on the 6600's rear panel mic jack is configured differently than the plug on the AntLion. If the Maestro C is similar to the 6600 then that could be part of your problem.

Check out this 2018 thread and the post from me which show the wiring diagram that I used to make the mic work with the radio: Antlion ModMic 4.0 mic profile — FlexRadio Community
