I have picked up radio TX and intercom noise. I am not sure what happened but it was nice and clear the intercom and the radio then all of a sudden a lot of noise and ATC has a hard time hearing me.

I will check for grounding wire connections (maybe one came lose) but other than that I am unsure on what to do. I have read about maybe a headset mic causing something such as this, so I will isolate my headsets one at a time to see if that is it.

Anybody got any troubleshooting techniques or words of advice?

Thanks,
Scott
