Galaxy DX949 Question

Hello,

I have a circa 2002-3 model Galaxy DX949. At some point today the unit ceased modulating signal from the microphone, and the talkback likewise. The roger beep still modulates and sounds via the talkback as normal.

I tried two different microphones with the same results. If I cup the microphone to my mouth and shout hard the modulation will raise up to about 40-50%.

Thoughts?

Thanks for reading!

Best,

Nathan
