Took a trip to Yuma for a couple of days. Posted some info for the YRCS and federal systems for the DB.
Here are some general observations...
Noted no activity on any of the VHF freqs in the RR DB, except Rural Metro. Looks like routine ops migrated to the trunked system.
YRCS: Mobile units on monitored agencies are encrypted; Dispatch for Yuma PD and FD, Tri Valley EMS and YCSO were monitored in the clear; Quechan tribe dispatch and field units both in the clear.
MCAS Yuma: this system was all in the clear and very active.
Yuma Proving Grounds: this system is heavily encrypted, with range clearances and maintenance the notable exceptions. Also a busy system.
The Sand Diego Imperial County RCS system is easily heard in the area, with Imperial County traffic.
