its not in the FAR's, the frequency assignment comes from the FCC.
FSDO would be a good place to start though, referencing the AIM
section that Burt mentions.

Thanks, I found the correct reference in the FCC code Part 87, subpart
K sections 87.319 and 87.323. It appears to be very specific that
what they FCC terms "portal-to-portal" service should not be occurring
on 123.3 or 123.5. I am beginning the process to work with the two
FBO's and the FCC to get them to change frequency of operations of air
to ground support operations. Both FBO's have used 123.3 and 123.5
for many years so it may not be easy, but if we don't work to hold on
to 123.3 and 123.5 we will be over run in the near future by jet
traffic setting up rental cars, fuel and catering.

I would love to hear Cindy's take on this and experiences she has had.

P.S. I know the UT, WY, MT and ID pilots are dealing with this, are
the Colorado pilots hearing the Bozeman, MT jet traffic (Yellowstone
Jet Center, 123.3 and Arlin's Aircraft Service, 123.5)?
