I have a loud buzz in headsets on both radios when transmitting while engine is running and on ground. When airborne, no buzz but tower reports transmissions are weak and unreadable. All is quiet (no buzz) and both units seem to work when on ground and engine not running. Ground reports transmissions back as okay. The King 155 was just sent out to Mid Continent and returned "repaired" with new digital readout (expensive). Re installed and original problem remains. The other radio is a Narco 12D and works fine other than loud buzz in headset. Have Narco glideslope with DME readout. Also have Tierra audio panel and PS1000 intercom. Have a generator -no generator whine detected when running. The local repair facility wants to replace the Tierra audio panel and intercom hoping that problem will correct itself. Does not seem to want to troubleshoot the root problem. Any thoughts or guidance on this would be greatly appreciated. Many thanks for your input. Mert - KDVT

I took my M20C in for an annual Dec.26. Last week was the first time I was able to fly it since. I still haven’t received the bill. I decided that I better go flying because once I get the bill I may not be able to afford the fuel. One of my big concerns was radio noise when I am in close proximity to the airport. I am not sure all that was done just yet but I was told that they put new connectors in the cabin ceiling. Not only did they not fix the radio noise but as soon as I took off, the tower said I was not showing altitude and told me to squawk 1200 on my almost new GTX345. Also, traffic no longer shows on the GNS530W or ForeFlight on the iPad. I was connected via Bluetooth. The avionics guy at the shop has since moved to another state. I guess I would like some ideas on where or what I should look for or do next. Any ideas would be welcomed. Thanks.
