Default FM for the Eddystone EA12?

FM has always been a legal mode for 80m in the UK, it's just that nobody
normally uses it intentionally.
Provided you're using no more bandwidth than normal AM I can't see a
problem.


Well perhaps not 'always'. FM was not allowed prior to about 1952.

When was FM first invented? BBC broadcast FM started in 1955.

The Murkins were trying it (for broadcast) in the early 40s (Google will
tell us).
