Post subject:  Wa. St. DOT VHF
Ok, I looked through the archives looking for a list of DOT VHF freqnencies and the area that the repeater is in. So far, I've only found posts where people think, and can hear, but no for sure where the repeater is.

So, I pose the question, with the DOT 151.xxx frequencies, does anyone have a list of where the actual repeaters are at and what area they cover? Thanks to all!

I thought they all went to 900mhz, I know one repeater for the 900mhz DOT is in bellevue at the intersection of 520 and 405

DOT went to 800mhz Multinet ages ago. I'm not aware of any remaining VHF repeaters though they have some sporadic crossband snowplow traffic. Here is all the high-band VHF DOT that I'm aware of:

151.010 DTMF telemetry
151.025 Snowplows - Hyak & Stampede (crossband)
151.040 Ferry dock traffic control
151.070 misc. handheld usage, old freq for Hood Canal drawbridge
151.115 Snowplows - Stevens (crossband)
156.120 Old freq for road crew/sanders + tow trucks on 520 bridge
156.135 DOT OSCCR

So they don't have the VHF cross link freq's anymore, which were the 151.xxx?

They still have them, it is really a dedicated receiver for the WSP mobiles to monitor select areas within the DOT pass areas. I think it was orignally designed for both agencies to talk to each other. 156.120 seems to be more active than 151.025.

Latest Info I Have Is:

151.115 - Steven's Pass area
151.025 - Snoqualmie Pass area
151.040 - Various areas on east side of Casade Range.

Unsure of tower locations. FCC database might shed some light on that.

I travel back and forth to Eastern Washington at least once a month and WSDOT is one of the groups I pay attention to, most especially when headed into the area of the pass in the winter months. I did a search, out of curiousity, of the FCC Database before one of my trips over a couple of months ago and it lists these frequencies for the DOT; 151.010, 151.0175, 151.025, 151.0325, 151.040, 151.0475, 151.0625, 151.070, 151.0775, 151.1125, 156.120, 156.1275, 156.135 (OSCCR) and 156.1425. All are listed with outputs from 5W to 350W, depending on which location you look at, and have a "V" next to them which I am guessing stands for "Voice". When I have heard the simulcast traffic east of Snoqualmie, it's been on 151.040 and 151.070. The units on 151.040, when not talking between themselves, were calling Seattle and on 151.070, they were calling Yakima. During some of the heavier snows at the pass in Nov, Dec and Jan, the units calling Yakima were going in service and enroute to the pass area (Bull Frog, Denny Creek etc.)

There was a thread about this a short time back and I listed the frequencies I have. One of the participants stated that he has had all of these frequencies in his scanner for some time, but has not heard anything definitive on them other than some intermod. The licenses for these frequencies are as recent as 2003/2004, which would be after their 800 mhz system went into service, and show to be licensed for various locations all across the state. Here is the link to the FCC page I use to do my searches:

P.S. 151.115 in the Seattle area, is the input for the WSP South King County frequency 154.680

And I STILL haven't heard anything on them, and that includes my recent trip to Snoqualmie. I'm thinking about reclaiming the spots those freqs are in for other, more nefarious purposes. :D

I hear Yakima signing out plows and Hyak as well. Some of the dispatch centers seem to have their own monikers. Hyak "58" and Yakima 50 ,instead of official sounding names like SW Radio and Olympic Radio.

I knew it was you Wil but couldn't remember how you spelled "Wilrobnson" :) I agree that the frequencies should be used for something other than sitting idle, but!, what wicked plan do you have for them? :twisted: It makes me wonder a little, since they have added these narrowband VHF frequencies with some high ERP ratings just in the last few years, whether they are having issues with the 800 mhz system and have some dim plan to move away from it and back to VHF in the semi near future! It's just a thought!!!!

I think the "58" and "50" numbers may be supervisors. I followed one of the dark blue DOT trucks back over the pass during one of the snow storms and heard them, using similar if not exact 2 digit unit numbers, calling plows, which have 4 digit unit numbers like 5817 or 5024, with tasks to do in locations we had just passed. "Hyak" or "Yakima" is just identifying which transmitter site they would be going thru, much like what WSP does.

From listening to the DOT prior to the move to 800 Mhz, it was my assumption that the XX units were the Radio Operator (dispatcher) at a particular facility. Examples would be 58 for the Radio Operator at the Hyak facility, 10 for the Radio Operator at the Seattle Roanoke (now Shoreline)Traffic Management facility, etc. XXX units I think were engineers, technicians, supervisors, etc, and the XXXX units were the road maintenance personel. Examples a snowplow on Snoqualmie Pass based out of the Hyak facility would be 58XX, a unit in south King County would be 14XX, an Incident Response unit in Seattle might be 10XX.
These days you can hear IR and motorist assist units on the WSP freqs using "Transportation XXXX" for a callsign.

I also seem to recall the bridge tender at the old Blair Waterway bridge in Tacoma funtioned as a Radio Operator for most of that region. If I remember right that was on 47.20 Mhz repeated, you could hear units all over the Olympic Peninsula and out to the coast.

My aunt dispatches for DOT in Yakima and I can confirm that the "50" unit is the Yakima dispatcher.

Also on our way over today to the meeting, the 151.XXX freqs were being used as downlinks from the 800mhz system as downlinks as well as simplex to someone marking times for traffic being let go and stopped.

I always wondered if in Vancouver they used VHF still or something else because I never hear them using their 800 mhz system down here.
