Did they switch to a new system or something totally different?
I believe most Kaisers are now using DMR or MotoTRBO. The new Kaiser in San Leandro is using 452.5 MHz with a color code of 10. Time slot 1 has talkgroup 101 and time slot 2 has talkgroup 102. The Kaiser in Redwood City is using 464.525 with a color code of 6. Time slot 1 has talkgroup 101 observed so far.
There are no scanners capable of picking up DMR/MotoTRBO at this time. However, a scanner modified with a discriminator tap and software can be used to listen. Also, using an actual DMR/MotoTRBO radio works as well.
