Listening to a chase tonight involving Kirkland PD as well as KCSO and they said they were switching the chase and search to PSOPS N2 Now I have this is all my radios yet there was no comms at all. I have the Tg as 62960 is this incorrect or did they recently change>? I even heard Guardian 1 come up on the Kirkland main and say they would contact county and everyone on PSOPS N2 yet i hear nada zip zero.... did these talkgroups change recently?

They probably had patched PSOPS to another talkgroup. When they do that, it changes the TGID.

Cowboymike --- Are you using a Bearcat or a GRE/Radio Shack scanner. The Pro96 does not pick up TGIDs that are patched -- or joined togather -- becuse they add 3 to the both TG numbers. The Bearcats should decode them -- . 62960 becomes 62963 when it's patched into another TG. Likewise -- the other patched TG is increased by 3.

Uniden scanners don't handle patches gracefully.

If the dispatcher patches talkgroup "A" to "B", the result is a different than if B was patched to A. The site calls the result either A+3 or B+3. Motorola radios know that if you've selected A or B, listen for the announced patch number. Watching Trunker is really useful here.

The scanners generally only have the first level of smarts: they know if you selected A, accept A+3... but they don't really watch the patch instructions to know to accept B+3 when you've tuned A. So to guarantee you'll hear the patch, you need to:
a) use a site for which the patch is active
b) have both A and B programmed and unlocked (which implies you've got an idea of what the 'other' talkgroup is)

The A+3 or the B+3 is dictated by which talkgroup goes into the talkgroup merge first at the console. No rhyme or reason. Whichever talkgroup the dispatcher assigns first.

I guess that it would be too good -- to hope that the NEW GRE scanners have a way to monitor all patched TG's .

Hey guess what! I moved back to Spokane County, where everything is still good 'ol VHF.
How simple. From a scanners point of view.

Bad move. Better think about re-locating -- again. In about 2 - 3 years there will be nothing left on VHF high band. And pick up a good scanner that covers from 700 to 900 Mhz. LOL -- But you'll have at least 2 to 3 years of good scanning till then. :D :D :D

I'll enjoy it while it last.
And it was a good move. Imagine... doing the speed limit on I-90 during 'rush' hour. I lived the first 25 years and the last 5 years on the west side.
I prefer over 'here'.

It will be interesting to see how the 700 auction goes after the analog TV makes the switch.

Not for long. You may be the first 700 system in the state

Is Spokane gonna be installing their own 700 system, or jumping onto IIMARS?

Wil, What's IIMARS? I think that it is just the county

I'm pretty sure Spokane County (and city) have'nt updated since VHF-Lo Band.
Same frequencies dating back to the 70's.
They probably are due for an update.
But hey, at least it doesn't rain for days and days.

:D Mark -- as always -- is "right on the noise". Spokane County + City is already halfway along with a new 700 Mhz system. OOOOPPS !!! You didn't hear it from me. You got it from the same horse as I did. It will include all agencies in the county.
