PA Statewide P25 Phase 2 System

[EMT1301]

I was referring to IV&D, not HPD, which is a different animal altogether. HPD is 700/800 only using 25 kHz channels, so the VHF sites are clearly not part of an HPD overlay.

My apologies. I'm definitely not familiar with the specifics of an HPD implementation. I was only aware that a site will be coming online this summer on our system HPD-enabled, and that they would have the full capacity of TDMA during data calls.

No apologies necessary! My knowledge of HPD is a bit lacking as well, certainly as compared to the bread and butter ASTRO 25 IV&D stuff. I am intrigued by the notion of HPD making use of TDMA with data, so I'm going to bone up on that stuff to get a better sense of it.

I guess at times we sorta take this thread into various directions, but I guess it's mostly all on-topic, sharing knowledge about how the system itself works.

You both know more than me, but I'm learning, so keep talking!

Game Commission...
been getting hits on TG's 12085 & 12086 today.... with PGC RID's...

; TG 12085

P25, BEE00.942, 12085, 1234001, 40, Normal, 30, 2019/03/22 16:24, "PGC SW/SC/SE Unit 10151/10159/12003/12006/12015/12033/12034/12051/12085"

This is interesting. Any voice traffic? "PGC 45" used to be a Headquarters upper management unit back in the day (like 10-15 years ago)...not sure if it would be the same nowadays. I monitored 45 a few times when the SE came on board the new P25 initially. I didn't hear anything that would make me think it was a radio tech.

I just gave it the generic "radio tech" tag because "they" (could be more than one/ a person or group?) always pop up on talkgroups testing radios.. "Radio Check" using different radios.. And sometimes the response back is "45 Unit"..
So yes they could be some admin group, managing PGC radio deployments..
Many times these radio id's return with a new PGC user assigned to it...
There were no voice calls caught on those 2 new TG's, just affiliations... But where there's smoke...

It's interesting because they will sometimes ask the dispatcher what ID they see on their end. and it's often that the response had 45 in it. initially I thought it was just a SC unit, but then they popped up all over the PGC TG's in any region.. So.. PGC Radio Tech seemed appropriate to me...

I don't know the official title, but Unit 45 is a biologist concentrating on the CWD issue with the deer heard. He spends a boat load of time in my area

I ran unitrunker on CHES31 for the past 24 hrs, only calls that it logged were PGC SW Dispatch 1 on 12051. No longer PSP any psp traffic. Are you getting anything on CHES02 for PSP traffic?

I've noticed a lack of K unit affiliations and calls on 1.65 LANC33 today.. I was just thinking.. Maybe a new site has come online that has sucked away all the activity??? DELA64 come online by any chance? Anyone?
Other than that.. Troop J & PGC traffic is normal..
Last K traffic was:
2019/04/17 23:18:59 Freq=153.443750 NAC=943 Registration; RID=1201429 [PSP K2 Unit 10164] TG=10164 [PSP K2 Media 10164] ACCEPT

Thanks to you guys I know I was hearing the Game Commission last night. How does the Game Commission work? Would I have been hearing local (Allentown/Bethlehem/Easton) Game officers calling to a dispatcher in Reading? The voice from the officers was pretty clear, however the reply was very garbled.

Not as of 1:30 this afternoon. I watch for it as well as Phila800 daily. Fairly certain still seeing k units on Devault and Philly sites.

Would not one expect to see Dela64 on some neighbor lists before it would be activated?

I also sniff around VHF band using spectrum analyzer regularly just in case they sneak something in.

Yes, you'd be under the Reading dispatched region.
Broken into regional groups.. First link is the believed to be correct TG breakdown, 2nd link shows the regional ID's map, from which you can see which area belongs to which dispatch.

They start at 123xxxx

Not necessarily... It (they) may not show up until it's on..
That's what happened with 1.57 YORK89.

I see those a lot. Have been noting them in the RID wiki as they come up.
also see Status and Query messages as well.. I'd also like to know
Time for another P25 class lesson..

Today, I saw both PSP and PGC units passing data on the Devault 800 site. That site gets significantly less traffic than the VHF sites. I tune in to it for a day here and there to check in. I'll probably tune back to one of the VHF sites for the weekend.

Radio monitor is a command sent to a radio that will key it up and allow what’s around it to be heard.

On ches02:

10161
10163
10164
10165

So is all PSP for this area operating off Ches02 VHF primarily. There’s been little to no activity for psp on the 800 sites.

Also, unitrunker on CHES02 displays no data capability but also shows no voice capability too?

PSP units appear mainly on the various VHF sites (i.e. Hibernia, Devault, Philly, Willow Grove). While the 800MHz sites are pretty sparse with traffic, they do have affiliations and a little voice traffic from PSP. I have only monitored Devault 800 for lengths of time, locally. But, I have seen PSP traffic on the Pocopson site on the scanner when I am down that way. Again, it seems rare, like on the Devault 800.

What redbeard said.

However, please be aware that you're likely seeing bad decodes due to a weak signal. If the Source and/or Target ID's look suspect, then it's almost certainly not a genuine message that was decoded. I've noticed that DSD+ tends to throw quite a few wonky messages out when it's locked onto a weak signal.

In your screenshot, I'm seeing a bunch of voice calls with no Source ID (radio ID) logged, which is a telltale sign that the control channel signal is very weak and might lead to unreliable data being falsely presented due to bad decoding.

@u2brent Same goes for the oddball messages you're seeing. If you're trying to pull in distant/weak signals, you're going to wind up seeing things in DSD+ that may not reflect reality, so be aware of that before putting any faith in them (or logging stuff to the wiki, frankly)
