[Milsurplus] Wide FM

To be honest, I do not know the current rules for FM deviation limits on
VHF.  But, I used to run an RCA Fleetfone station on 52.525 with 15KC
deviation and talked to my good friend about 50 air miles away all the
time, he was using a Motorola station, wideband too, and it was like
listening to the FM BC band, the audio was so perfect, and both of us using
carbon mics. .  I still have that FleetFone and it still works, but have it
throttled back to 5KC deviation, not because of any regulation, but modern
rigs looking for 5KC deviation, the 15KC just goes right past them with odd
sounding audio on their end.  I retuned the IF and discriminator in order
to get enough audio from the 2 NBFM stations I have worked on 52.525 over
the past 34 years.  Nobody seems to know about 52.525 anymore.  Worked all
over the Caribbean, into Alaska on FM  one time, but now the only thing on
6 is FT8. (And me and another buddy on 50.4AM once a week.)  The Fleetphone
is normally on almost all the time, but silence is all I get.
