I recall discussing this back when I was contemplating the
restoration of a Sonar HF exciter and it was determined that
the legal restriction made it functionally impractical to
run FM below 10M, despite the technicality that it was
theoretically possible - not sure if it was that the
modulation would be too pinched or if it was that FM was
insufficiently efficient to make sense there. Memories
fails other than that I was persuaded that it would be a
Quioxtic undertaking.
WDYT?
