Current TGID update -- confirmed voice on these channels:
60001 - Encryption
60100 - (Chat related to 60102)
60102 - Seattle Traffic (I-5) (basically these are the TOM units on WSP -- but only use number callsigns. A few work the main I-5 freeway and one is assigned to express lanes.)
60130 - Security (but not sure where exactly) -- just heard encryption today but it's mostly in the clear
60150 - (Random chat)
60850 - WSF Ferry Operations - Primary
60851 - WSF Ferry Operations - Secondary
There's another one I'm spacing at the moment. 60x00 which is the "shop" but not sure of exact location. It definitely is in King County.
PS. Lot of activity today due to high winds. Apparently a tree fell down onto 520 blocking traffic in some lanes. Also a tree down on 405. I'll post recordings later tonight.
