Radio encryption in Marin County
A single agency is tracked in Marin County: the Marin County Sheriff, verified as encrypting all monitored channels with P25 DES-OFB on the Marin Emergency Radio Authority (MERA) P25 system. All three catalogued talkgroups on that system are currently in the clear, with none encrypted, so a scanner will still receive documented system traffic even though the sheriff's own channels are listed as closed. The talkgroup count here is small and reflects what has been documented rather than everything carried on MERA.
