Hope someone can help. New RV10, Two SV1000, G340 audio panel, GNC255A and GTR225.
Everything is working fine, but I have a soft crackling sound on the headsets as well as the speaker. This is on the ground with no engine. So when you fly you cannot really hear it. But I have now connected the music input of the audio panel and found that this crackling is just loud enough to mute the music for short intervals. I do not know what will happen in flight but wouldreally like the musice to work for all the boring test hours.
In order to try and isolate it I have done various tests and found that if I leave the radios on, but switch off the SV's and then on again, the noise starts the moment the screens are finished booting up and ready to use. Grounding of the avoinics and the SV screens are seperate on two terminals on the bulkhead behind the panel and are about 12" apart.
Did anyone else have this or can advise what to look for?
Much appreciated.
