Have you considered swapping the antenna leads (at the tranceiver end) to
see if it's a aerial issue?

Our "new" '79 M20J came with a 2 year old Garmin 430 GPS and Garmin 340
audio panel. The backup radio is an ancient King 170B. I must say that
the reception on the Garmin sucks compared to the 170B. Am I doing
something wrong or is this just something I have to live with? To me for
10 grand the Garmin should run circles around the 170B . Thoughts?
Don't flame me too bad I have only flown this plane a couple of
times... Thanks!!
