Almost right..
Marin County Fire will, as Inigo mentioned, be taking over two old Marin DPW freqs for a Marin "local net" (CDF style) when the MERA system comes full on. This has been planned for a long time, which is why you see the freqs listed in the CDF radio plan. Most CDF mobile radios have thiese frequencies programmed in. Hopefully this will take place in 2007- if we are real lucky, this season.
Currently, MCFD uses CDF 2, tone 7 as a command channel for SRA wildland fires anywhere in Marin. This can be patched to either MERA H5 or H7. MCFD also uses White 2 or 3, and new this year, CDF Tac 1 and 4, for wildland tactical channels.
