San Diego City 700MHz System

[SDBud]

I think SDMA 10, 20 and 30 still exist but I think they’ve just fallen out of favor as mutual aid hailing channels. Since the fleetmaps have all been updated to have both LE and fire talkgroups accessible, and a mix of the 700 MHz city system and next gen RCS (with RCS having an abundance of mutual aid/hailing talkgroups available) I just don’t think they’re being used as much in practice.

Those have never really been used much. They were supposed to be for comms between PD and FD, but PD never really got on board, and FD never seemed to care much either.
