Their primary operations are (for now) on UHF conventional. Transit PD and a few other things are on the trunked system. Power & Facilities have two 800 conventional channels.
Sound Transit is on the trunked system, but I haven't nailed everything down yet.

Sound Transit buses are all on the UHF Metro freqs. Sound trains I dont know. I do know low low power
800mhz trunked will be used in the tunnel for trains and buses that operate there.

The freqs are in the KC database here

Sound Transit's buses use the same freqs for whomever is operating them. For example, a bus on route 577 is operated by King County Metro and will have all of Metro's radios installed on it. (Also the bus will be stored and maintained at one of Metro's bases--Sound Transit doesn't have any bases). Or a bus on Route 592 is operated by Pierce Transit, and has a PT radio and other PT stuff on it.

KC Metro Transit
23952 Transit Police Primary
23984 Transit Police TAC
24016 Metro Transit F-7
24048 Metro Transit F-8
60304 Bus tunnel security

Primary: Dispatch, etc. for Transit police. Dispatched by KCSO. patched to one of the other KCSO dispatch channels during off-peak times, but I forget which one.
TAC: Transit PD's TAC. Rare use.
F-7: Link Control, District Supervisors, Sam12 from the tunnel, and Transit PD can all talk here. Dunno what its purpose is. Rare use.
F-8: Used for Transit PD to talk to the bus dispatchers. Rare use.
Tunnel: Used for the "security" guards to talk to each other throughout the tunnel, from IDS (International District Station) to CPS (Convention Place Station) and everything in between. They're a contracted service from Northwest Security Patrol. All Sam units. Sam-12 seems to be the head honcho. Sam-12 can be different people at different times of the day. Also the little hut along the busway just north of its intersection with Royal Brougham is heard here. It identifies itself as "Royal Brougham" or sometimes just RB. I think I've heard Link Control here too--who controls movement in the tunnel. Constant use.


Sound Transit
All of these are related to Link Light Rail.
60048 Mainline OPS 1
60080 "OPS 2" AKA "Channel 2"
60112 "Channel 3"
60144 Yard Ops
60176 "Channel 5"

1: Where most of the action is. Trains, contractors, and Link Control all calling each other. Controls movement and ROW (Right-Of-Way).
2: Seconday channel for above.
3: Not sure of its purpose, just referred to as "Channel 3"
Yard Ops: Coordination for moving trains around in the yard (and probably inside the O&M too)
5: Not sure of its purpose, just referred to as "Channel 5"


ST seems to also have 60208, 60240, 60272, 60336, 60368 but I've gotten very few hits out of them. There are two independent sites inside the DSTT. If they're doing work inside the tunnel, it's possible all the radios will roam onto one or both of those sites and not onto anything else, so you have to be in or very near one of the entrances to pick them up. This shouldn't be happening as much any more--the tunnel is open from 05:00 to 19:00 weekdays, but starting May 30, it'll be open 05:00 - 01:00 Monday through Saturday and 06:00 - 00:00 Sunday. LINK's opening weekend will be July 18. Free rides on special service July 18 and 19 and regular service begins on Monday July 20.

For channels, I have:
452.2750 (4)
452.6500 (1)
453.5250 (7)
452.3750 (data)
452.8000 (data)
That's based on listening. Channel 1 is only trolleys.

Mine came from listening. NWFD lists two of the channels as PD channels even though PD has been on the trunked system for quite some time.

Channel 3

453.3750 is ch3 and some data. I think the data is a time update to the drivers box.

But there is voice on this channel most of the time as well.


otherwise I agree with Atomic Taco on all.

No I am not sure what the data is just that there are lots of voice traffic as well!

data could be anything just guessing that it was time since it seems to
happen at intervals instead of random or semi random times........

Here's the CWID I recorded off 453.375.

Since I don't speak Morse code, I pop a recording in a waveform editor (I like Audacity) and then you can see what the Morse "looks like".

81448251.gif


In this case, it translates to WPXL485. If you want a fun one to decode, listen to 862.2625.

Nice

Nice..... but I know what that morse is and why they have to announce their station id! They
do it on the hour and on the half hour.

Not what I was talking about. On CH 3 there is a data burst from time to time as well as
normal voice traffic. If you listen for a while and have a good enough signal you will hear it.
It does not exist on any of the other 'voice' channels. Sounds a little like some of their
telm on 452.80000.

Does anyone know how this system is set up?

There are a number of Metro Bases. Wouldn't a bus talk to it's own base, or is there some kind of central communications headquarters for Metro?

For instance, since the Trolleys only come out of Atlantic Base, would channel 1 be only an Atlantic Base channel? Is there a channel for each base?

I wish I could glean this stuff from my mother in law. She's a Shop Steward with the ATU, and has been driving for nearly 15 years out of East Base in Bellevue. She doesn't have much of an aptitude toward the technological, so when I ask her about the radios, she gets a real blank expression on her face.

"Drive Bus, Cash Check" she says.

*sigh*


Anyways, I live right on top of the beacon hill Link Light Rail tunnel. I hear a lot of traffic on the 60048 TG but I don't listen that often, unless it's a REALLY slow day everywhere else. (I only have the one scanner, so it's usually listening to public safety stuff).



EDIT: Well, I went to Metro's wiki page, and discovered that there is indeed a Communications Command Center located next to the Atlantic-Central-Ryerson block of bases.

Yeah, the communications control center coordinates all voice traffic. During slow times one dispatcher will handle more than one channel, but during peak times they'll have one dispatcher for each channel. Check out this video.

I'm not sure how they divvy up channels. Listening to Channel 3 a bit over the past few days it seems to be only buses that run through Downtown. I didn't make notes so I'm not positive. I just remember hearing 174 and 550. Those are actually tunnel routes, but some of the others I heard on 3 weren't. Oh yeah, I heard a 73 and 99 too. I'm definitely interested on how they split the channels though.

The different bases are there for capacity and locational issues. I know the 194 and 174 are both out of South base--those two routes operate between Downtown Seattle and Federal Way. And I bet the 41 is out of North base since it's only a few miles from the northern terminus of the 41. Not everything makes sense though--if you look at one of the afternoon runs on the 311 after its final stop in Duvall the operator runs the empty bus--from Duvall--to Downtown to do a 257. Some of this might have a little bit to do with that senior drivers get first pick on which routes they want... I dunno on that one. Every operator can't be qualified on every route, so that might have some to do with it too.

Oh and the trains will start running in the tunnel on Monday. Non-revenue, non-passenger service; details here.

I'll have to keep listening to hear that data burst.

That data burst is on ch 3 ! hehe..

I know that the channels are picked by route and run numbers. Central has Ch 3 and Ch 2
so does Ryerson Base. Trollys seem to be on Ch 1 . East Base also uses Ch 3.
This is all I know for now.

Thanks for that Link. It seems Metro is doing more on their web page as of late!

Talking to a train guy, found out that the Sounder's ops are on the BNSF freqs--not surprising since it's operating on BNSF's tracks with BNSF people operating them.

"BNSF road freq in this area is 161.100, seattle terminal dispatch is 161.160 and centrailia dispatch is 161.415
one can also listen to streams here: Live Stream"
