Late to the party here:
CMARS White 856.2625 CSQ
California Multi-Agency Radio System (CMARS)
Source: Government Radio Systems, California State Agencies, 1999
Back in that time, OES would deploy portable repeaters on CMARS freqs
for LE special events or limited duration programs in addition to static sites.
If memory serves, CDC transport bus operations used to use CMARS.
Repeated this channel would have been called Purple and used 110.9,
simplex it was White.
RIP Bob Kelty, your work lives on.
