Interop problems.
CHP H30 (helo, I assume) on the Sunnvale scene., Unable to establish comms. Helo has CHP Ruby, Blue, and CLEMARS. SV patrol units can't come up on CLEMARs. Sounds like they are resorting to cellphone contact.
SCCO did a reverse 911 call just after 9AM. I received the alert several miles away here in Los Gatos, which is rather strange. It might be because until a couple of years ago I owned property in the SV area being searched.
10:10AM -- Air2 is up. Baymac480 and CLEMARS3 155.475 have been linked. All transmissions on Baymacs480 also are on CLEMARS and vice versa.
