I have an RV-8 with a Skyview Classic and two Dynon SV-COM-425's and the Dynon intercom. I have about 67 hours TT on the plane. I have recently over the past 10 hours or so developed a constant static problem over both comm's and the intercom. During startup, engine run-up and taxi the radios perform without issue, however once I reach a few hundred feet after takeoff the static becomes constant during receiving other aircraft transmissions and intercom communication with my passenger. If I press the PTT to transmit, the static stops and I transmit fine. Once I release the PTT, the static starts again.
I have tried different headsets to no avail. I have checked all radio and intercom connections, RG-400 coax connections, grounds, headset jack isolators, cleaned the antennas, etc., and all seems in order. I have also fiddled with the Skyview com settings but no change.
I also reached out to Dynon Tech Support, and their response yesterday was "It sounds like a radio problem, which can be solved by upgrading to one of our newer models", at a cost of course. They said they do not repair the -425 models anymore. Granted I purchased both radios and the intercom new in 2016, but I did not finish the build and fly the plane until May 2021. I have a hard time thinking both radios crapped out at the same time after only 67 flight hours.
At this point I am at a loss and looking for additional thoughts on what to try. Thanks in advance for any suggestions.
