July 30, 20251 yr Hi 🙂. This is a different issue. The COM2 only shows 2 decimals. In the US these 25 khz radios should tune 3 decimals by ignoring (not rounding) the third. So does the COM2 radio work? I occasionally hear mic key sounds but not ATIS (that COM1 picks up).
July 30, 20251 yr Author Okay I learned that the GPU (ground power) seems to provide power but at least COM2 doesn't work correctly with it. After engine startup, both COMs work. The switches on the audio panel are all over the place. I guess this is still an improvement since I can now store 4 COM frequencies.
