As it is, we have exclusive use of the frequencies on 72 Mhz, wedged between other users that are only 10 kHz from each of our frequencies.
It is actually worse than you have indicated. This quote is from FCC rule 95.207(g)
"These frequencies are not afforded any protection from interference due to the operation of fixed and mobile stations in other services assigned to the same or adjacent frequencies."
I did not realize that there could be other devices exactly on our frequencies until I read this section.
