But Mike gets dropped sats even without keying the mic and with all

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.

RFI issue is with the COMMS and the Garmin. RFI was no issue with the other two GPS receivers listed.
