But Mike gets dropped sats even without keying the mic and with all
electrics off. That can't be totally EMI. It has to be a bad 396 because
his other two old faithfuls hung in there throughout the flight.

Not necessarily. Garmin uses a different (active) antenna. Not sure
about Magellan, but Lowrance uses a passive antenna. It is possible
that the active antenna is amplifying noise that has infiltrated the
system, though that's probably a stretch. Mike definitely has a RFI
issue with the coms, though, because he can repeat the failure reliably
when he transmits.
