Well for what its worth, Charles is pursuing an 800 MHz solution to
address some of these concerns. And your assumption is correct. Most
of the "units listen first" is blowing smoke as they can't hear each
other anyway.

That explains it. In my opinion, that is not an efficient or
effective method of communications especially during emergency
situations as I have heard the dispatcher frequently limit transmissions
from/to a specific mobile unit. Probably the other mobiles cannot hear
each other calling the dispatcher and QRM the frequency. I think their
county EOC in "lessons learned" needs to rethink that communication
plan.
