Europa-List: radio interferance

[danny shepherd <danny@mcwalterscafe.co.uk>]

Hi All,
            Are there any avionics expert who might be able to help ?
I have a Funkwerk ATR833 which has worked ( bar having a new face fitted 
) extremely well over the last six years. but now works fine until I 
start the engine, then a lot of interference, virtually unreadable both 
transmitting and receivering. I did have the panel off to remove the 
hard wiring for a gps which I dont need anymore. Sounds like a grounding 
problem to me.
I would appreciate any advise.

Regard. Danny. G-c.e.r.i TRI XS
