Background: RV-12 started pre SkyView with original wiring harness, shifted to SkyView with conversion harness. Flown since 6/2012 with no significant issues. Radio was fine on flight last week.
Problem: Saturday morning I had no audio from the SL40. No static when the volume knob is pulled out to bypass squelch. Normal messages heard from the SkyView ("Dynon SkyView" on start up and "oil pressure" repeated frequently when the engine is not running). The pilot / co-pilot audio is OK (well, no different from normal). Push to talk produces a pop in the audio but no side tone audio and no transmission occurs (checked with handheld radio a few feet from the plane). I have visually inspected the wiring in the panel and see no abnormalities or obvious wire breaks. Antenna wiring is OK. Nothing was disturbed in the panel or wiring since the last flight when all worked well.
Questions:
Does this failure pattern sound familiar to anyone? Anyone had an SL40 just quit working?
Best bet from those of you with experience in radio issues? SL40 vs intercom vs AV5000A vs wiring??
Garmin wants $550 plus shipping to check the radio. Seems like a better choice might be to replace the SL40 and original intercom with the GTR-200. I would appreciate comments from those of you who have done this, particularly regarding where you bought the radio, did you make your own harness or buy one and if so, where did you get the harness, etc?
Thanks for any help.
