Hi John,
You seriously need to keep humble, informative and after much
grip and grin handshake introductions... after much time and
ear bending try to locate, advise and steer the overall radio
frequency officer for the base/location into the better idea
of moving down the band. It's just a basic matter of them
reprogramming their equipment into the lower frequency range
where they'd experience much enhanced operation.
In the real world it can be stand off and in typical bull in
the china shop ham attitude I've see with many of our "Alpha
Hotel" west coast repeater owners ("AH repeater owners tend to
be a'plenty across the US) you don't want to say or do anything
wrong or to pi$$ them off.
You need to carefully id and contact the right person at the
base where the system is installed. Then you need to carefully
try to open a dialog with said person and after supplying much
much information and a very viable alternative let he/or she
hopefully think and act on moving their eplrs system down the
band to a less crowded area where all parties will be much
happier.
cheers,
s.
