I just mounted a new SL-30 in my 7a and find that when I hit the PTT switch, both panel mounted LED'S used for my trim system go nuts. When I have my headphones on and blow into the mic, it lights up all of the led's like a power meter. I did a search and found some builders ran shielded wire to the indicators, and the problem was resolved. No luck in my case. It seems to be an intermittent problem as well. I can key the mic one minute and it works fine. Then key the mic again, and watch the led's move erratically.
All of the RG 400 antenna wire, runs through a separate conduit as far as possible from the led wiring. I have a comant bent whip antenna mounted just behind the spar under the pilot seat. The wings are not mounted at this time. Just wondering if any other builders had the same problems and what they did to resolve it.....
