Here's my text file which has nicely spaced columns...

Comes in at a decent 1-2 bars with the antenna disconnected from the airport drive

Sweet thanks for verifying. I'm going to do some mobile scouting over the holidays. I always forget to check the Intercept database for trunk data, but I was able to cobble up some location data based on it. The marked items have already been tagged by my XT/Pro96Com. I'll scout the other sites and see if I can get any more Site data.

Possible locations:

*Site 106 Seattle, Federal Building
*Site 107 Gold Mtn, Bremerton
Site 108 Enumclaw, Grass Mtn
Site 110 Pierce Co, Tacoma
Site 111 Thurston Co, Olympia
Site 117 Snohomish Co, Lynnwood
*Site 118 Cougar Mtn, Bellevue
Site 125 Sea-Tac Airport
Site 134 Kittitas County?
*Site 143 King Lake, Skykomish, Monroe
*Site 164 North/East King Co?

Decided to listen to this today. Nothing unencrypted yet.

I'm in Redmond getting clear (but encrypted) traffic on the south seattle site according to the notes (167.7125, 167.4625). I'm hearing these talkgroups, again all encrypted:

I was listening last night and had the blain BP working butts off for some hit and run

One of the PDX IWN sites here, I am pretty sure relays TSA operations in the green on one talkgroup. When I catch it again, I will get the talkgroup.

Yep, it's a voice frequency on the Blaine site.

Blaine site Control Channel
167.3125mhz

Site comes in real good in Vancouver

the New generation of trunktracking (Uniden or GRE) digital scanners should be able to automatically figure out the P25 voice channels by only entering in the control channel frequency into the radio.
