WA Dept Of Transportation (P25 System) Updates

Most of what I've been hearing sounds like analog traffic patched in. Very difficult to understand. There was some traffic from native P25 users (mainly WSF) but wasn't the majority. TGs were not active all the time, probably only when native users were affiliated with specific sites listening or scanning those specific TGs. Was very prevalent during the snowstorms earlier this winter. Listening to the Eatonville, King Simulcast, and E Tiger sites. Was contemplating adding those sites to Calls but that PC is just about maxed out on memory/CPU with the systems already running on it.

This sums up WSDOT P25 in general. Their audio sucks. Way too much bass and very hard to understand them -- even the non-patched users.
Audio quality of digital operation in general sucks. But I agree their native subscriber units are worse than average. The WSF folks have sounded the best out of all the traffic I was listening to, that could be due to the radios installed and environment they're operating from (captain on the bridge of a ferry vs. someone using a portable on the side of a freeway).
Are you listening on a scanner or a real radio?

According to my SDS recordings yesterday SW region seems to be starting to patch in the EFJ traffic over to P25 now. You can tell because of the soft beeps after they dekey. Some of it sounded horrific, some not so bad. I think the techs were doing some level setting as it sounded better later in the day. Their pure P25 traffic sounds pretty good, even their users have liked it.

Uniden 996P2 and SDS100. You're not suggesting I put my APX on the WSDOT system are you?
For you guys living in the Cowlitz & Lewis County areas, which repeaters do you listen to (that get traffic)? I want to remove all unnecessary ones to speed up scanning.

Finally hearing tones on 60810 on the King County Simulcast. No voice as yet though. Correction: now a male giving test counts.

Do you have a SDR? This is what makes them so good. You can [visually] scan the 770-775 Mhz band and find out which control channels are in your "zone of operation."
Airspy/SDRTrunk for monitoring this particular system (which produces better audio than some radios do). One can tell the difference in audio quality when comparing to other trunked systems (PSRS, SS911, WSP700, etc.) but since this system is still in the process of implementation I'll cut em a break
. Could also just be the particular users I heard since it appears that not very many native users are on it yet.devicelab

Nah they're just being lazy. This system has been online for a while now and you can't tell me they don't have 10 minutes to listen on a scanner to see how their system sounds. Granted, they could care less what scanner users think about their audio quality -- but from a technical perspective -- this would be a valid [interoperability] test.
I do, but it hasn't been much help. I used the RR database and imported the relevant information into ProScan, but get NADA, and yes, I'm using the P25 and not the LTR option although I've tried both.

I'm in Cowlitz and just started listening to P25 this past week. In the RR Cowlitz Co database, at the very bottom you'll see "All Trunked Systems". Look in Justice Integrated Wireless Network and you'll find the western Wa county lists for wa state patrol. I've been picking up Kelso but also have clark and lewis programmed in though I haven't gotten any hits on those two. I've also picked up 2 talkgroups that are unidentified and not on these lists. They are 13301 and 13120.

Did they identify it as the "Mica" site?

I'm getting Cowlitz traffic from the Green Mountain site. I'm right on the edge of the Lewis County site and a little farther outside the Clark County site so I haven't heard anything on those. Green Mountain is working clear on my systems.

I would listen to BawFaw, Signal, Davis, and Rainier for the I5 areas. To the east up Highway 12 you would probably have to add Hopkins, Dog and Packwood.

That system is the federal system that does carry a little bit of WSP traffic. I don't believe you would ever hear WSDOT traffic on it. The talkgroups you posted are from the federal side and most likely encrypted.
They did not. I should have clarified I heard it on the Mica site.

So you are/were in the Spokane area when you heard it and not in Bellingham? That's my confusion.
