After they stopped and pulled over they saw a black and white VW bug drive up behind them. They got scared as hell and then saw the Geek Squad logo on the door.

The previously referenced 151.025 is for one of the crossband repeaters that allow WSP to talk to the DOT units (who are on 800 MHz). They also use 151.04, 151.115, 156.12 in various places - I haven't got them all nailed down.

As a point of interest -- 151.0400 is also used as a simplex channel at Coleman Dock by K9 & VATS troops assigned to the area.

Happy listening.

Also, add 155.460 which is car to car in King County.
This is simplex, so you will hear traffic that is close.

MTM is correct though, you may be in a shadow.
Coverage in that area can be tough, depending on your specific location.


Not necessarily. There's also a south-end transmitter on Gold Mountain. How often it's used is not something I can say with any degree of certainty.

So If I might be driving one or two miles over the limit and didn't want a ticket, and I had the input side 458/465 freq's in I would hear if a WSP was close and how close by signal. Right? Did I just invent a CloseCall for WSP? I'm hoping the MDT's don't put out 90 W's. Remember I live rural, I'm not thinking downtown Seattle.


The MDT radios push about 25 watts. I think we're limited to 30 by our license.

Happy listening.

Flash, My understanding is that they are dropping use of some of the Old DOT VHF channels -- and only one and maybe two will remain for cross-band patching -- which will allow for re-use of at least 3 of the 5 Old VHF channels. It might end up that the WSP could add a new pair -- just for use in the North Seattle area -- from I-90 North to the Sno County line and West of Lake Washington. They could use a repeater downtown. 151.025 might-- MIGHT -- end up as a new WSP "Area" channel. If you live or drive through King County --- I would program in the 151.025 and give a listen.


Kind of a thought on this! And maybe I'm wrong because I just can't hear it, but 154.845 doesn't seem to be used at this time in the Seattle/Puget Sound area! It could be used as an output freq for a repeater in the area w/151.025 as the input if they were going to add a duplex system. This used to be the Everett area frequency years ago. As far as I know at this time, RItzville [Creston and Lind] and Colfax [Steptoe Butte] are the only places in the state they are used. This is pure speculation but, a possibility for a pairing of frequencies!

154.845 is the input to the 155.655 (R) Everett Area channel. Nice try -- and I'll give you a silver star for your effort and idea.

Thanks... I feel Special now!.. :D Guess thats why I can't hear anything on that freq here on the eastside! I suppose it is "possible" that could be changed if the DOT gives up a couple of the 151.xxx freqs or drop a couple of the narrowband freqs like a 151.xxxx and a 156.xxxx to make a new pair! Again.... just wishful speculation!.. :)

P.S. If this [wishful] speculation should come true, can I get a GOLD star!.. :lol:

Its easy to say "this group now uses these frequencies and those guys use this one now".

Its a whole different matter to get every one of their radios, portable and mobile, back into a shop or a tech out to every radio and reprogram them and the repeaters. If you have different models and manufacturers it's typically a unique codeplug that has to be made for each type. Add your regular shop work load on top of that... omg. Call out dead.

Oh ya, shops are already doing this for rebanding. *headdesk*

I would agree that there would be a "headdesk" issue but, if it is an issue of (1) Safety and (2) Operability for the Patrol, then that [headdesk] issue won't be anymore! If you think about it, I would imagine that the only ones they would have to worry about re-programming first would be the troopers that work the area in question. Everybody else would be secondary after that, other issues excluded! And it's not like they haven't taken on these tasks and issues before with all the other modifications they have done to their system/s in the past few years! But more than that, this is all just pure speculation on our parts cuz we want something new to listen to! So ultimately we may all just be... :horse: ..... :)

Cheers!
Chuck

Actually, I have never undertaken a task on the scale of WSP, but I have done similar projects with much smaller user base, yet spread over a few regions that required cross region operability.

It is a very difficult process and requires a clear and concise plan that doesn't just fall together.

Basically, once you hit "go" and start making changes, missing even ONE seemingly minor "technical" detail ,in reality can turn into an "Officer Safety" issue as fast as a flick of the switch. And going backwards is not always an option, either.

Even if, from a technician's perspective, that claim (of Officer Safety) is total BS (been there but fortunately not from my doing) I can tell you that it is hard to debate a PO'd cop with a gun. Personally I will not try it.

If he/she feels the screw up, it can be a career burner for a tech, or his/her manager.

So yes, from our armchair it seems as if "ALL ya got to do is :x-y-z" but the truth is guys like Wiz, Sean and the rest of the gang here in those positions do work hard for the money, and NOBODY wants to get caught in a fubar when restructuring a system. Also, despite doing restructures in the past, there is always the potential for a fubar, if things are not well thought out.

I have a great deal of respect for the folks who have to do this. In a geeky sort of way, I always found these challenges to be truly fun. Go figure.

WSP's radio system sounds like it was setup by the same people who setup the system for Oregon State Police :)

I'm not sure in which way or how or why you think that the two State Police radio systems sound alike --- but Yes and NO. The very first use of radio for the WSP came about in the early 1930's. WSP Motorcycle Patrol units made up most of the field patrol units. A radio receiver was attached to several motorcycle units in the Vancouver - Clark County area. They were set to an AM broadcast channel out of Portland. The station would get a call from the WSP office and would then broadcast a message to the WSP units. So, the WSP did at one time have some connection with Oregon. However each state has it's own radio shop and radio techs. So -- NO, the VHF radio systems were not built by the same radio shop.

I was just making a lame joke. Some of OSP's system has that quirk where you can hear the mobile units being repeated but not the disaptch and vice versa.

BTW, would it be wise if monitoring WSP in Clark County to not set a PL in the radio? I've gotten two awnsers from people not on this board that yes I should set a tone of 100.0 (which is odd since thats not listed anywhere) or no tone at all because Klickitat County has a PL.

i never put tones unless there is some horrible RF-hell in the area, as you never know what you might find with no tone.

Certain WSP zones are still using mountain top remote base stations and haven't yet gone to a fully repeated system.

With remote bases the dispatcher selects what area she wants to talk to and only that base station in that zone keys up. If all zones keyed at once, without proper setup and equipment, you wouldn't be able to understand it through the noise it would create. Rx audio then comes back through that same path from the remote base, typically microwave or lease lines but VoIP is becoming more popular. When a troop identifies an area at the beginning of the transmission it's telling the dispatcher what zone she should reply to.

It's a good system for covering large areas. It's also why WSP dispatchers repeat a lot of what the troopers say in order to help the rest of the units know what was just said.

I'm always open for correction here, I haven't actually laid eyes on their system but this is how I understand it to work.
