Hey, guys. I work as a dispatcher for a security company in the Bayview district of San Francisco, CA. Part of my job is to monitor radio traffic in the area, and I just noticed today that SFPD is switching to a channel called "B5," to work the 49ers game today. I checked the frequency database, and I don't see "B5" anywhere. I'm posting this here because I was hoping someone maybe solved this 'lil puzzle already.
