[Elecraft] KX3 no transmit audio

[Neil Smith]

Hi All, 

For some reason on my KX3 using the MH3 mic, I can no longer get any audio on transmit. Vox operation still works to key the radio, but it is just an empty carrier. When I have the alc/comp meters up, I can see the audio levels rise and fall with my voice. TX power is set to 10W, not in split mode to a different mode. All the MH3 settings from the manual are correct. 

I have gone through the troubleshooting guide in the manual with no luck, so if anyone might be able to help before Elecraft is back open I'd appreciate it.
