Wow, so I might be "jamming" the EFI hey?
That, if so, would be interesting with my Jeep friends who have EFI's on 
their machines. Pull up along side of them, turn my engine off, and blast 
them. Funny to think about. 

A possible symptom that might work against this being the cause is the 
dreadfully low voltage in the power feed wire when transmitting.

Thanks, John.
