OK Terry,
How did you handle the RFI generated by the Magna's Engine Management
Computer?

In the XYL's Magna a radiated signal of some sort blitzes everything
other than b'cast or 2m FM! It's a constant pitch, constant level buzzz
which pervades everything. B'cast am is a wipe out unless we're withinn
10k or so of a station!

The only change seems to be whent O2 sensor loop goes in and out of lock.

I'll post this to the group... someone else may have a clue!!!
