Any chance it's an
SL30? My SL30 wired to a Bob Archer
wing tip antenna would almost kill the engine when transmitting. My 430 wired to
a belly antenna worked fine. Tracy added capacitors to both the A&B
controller MP sensors. The capacitors eliminated over 90% of the interference
but a little is still there. I have the SL30 removed from the plane
for now. Garmin has issued a service bulletin that may be related. Need to
send mine in.

Here is an update on Sam's RV-7A progress with 13B...
"I believe I bucked my last rivet last night on the forward upper deck. The
plane will be heading to the airport in a couple weeks but will be making a
detour to the paint shop on the way. You will like this, when I completed
the wiring I ran the engine one more time to verify the newly completed system.
To my amazement everything worked, even the interior lights, until I hit the PTT
to see if I could pick anybody up. When I pushed the PTT the engine would almost
quite and the EM2 would start to scramble, even the FM radio on the garage wall
would quite. After a calls to the Gulf Coast Avionics techs is was soon apparent
that they led me on a trouble shooting trip that led to nowhere. After a weeks
vacation from work and the plane I came home with a fresh mind and discovered a
direct short to ground from the coax center conductor to the radio case. A bad
radio right out of the box".
We should be hearing about a first flight in the next few months!
