Help with SL-30?
My SL-30 COM side has these symptoms:
1. very weak transmit & receive (10-13 miles max., usually, sometimes less).
2. reception not affected by whether controller is left or right side.
3. when transmitting, I see spikes in my egt graph on my GRT EFIS. They are false.
4. when transmitting, if using TruTrack AP, it pitches up strongly.
5. some controllers report background hiss/noise, even on the ground.
6. maybe unrelated, but the built-in intercom is noisy, too.
7. I'm using an Archer COM antenna in the wingtip. In hangar testing, a Comant 122, brand new and meter-verified pulled the same trick on the AP.
8. When transmitting through the Archer with my Yaesu handheld, no AP issue.
9. I can't find any shorts or opens in the antenna wire, all the way back to the connection at the back of the tray.
10. The NAV side works superbly well. It's in the other wingtip.
It's driving me crazy. Any expertise you can share would be gratefully received.
