LVMPD P25

My computer on procom96 shows the system nac as 5f6 but my psr500 scanner shows it as 5f9? Wondering why?

That is a bug with the PSR500 mine does the same, but it shows the correct system number when it alternates screens.

 

[Dick33]

Well sports fans looks like we got us a system going now, 774.23125 Sunrise YG channel showing system 5F6 site 2 also site 9,11 connected online. Great job Mike and Motorola.....

 

[Jay911]

Site 9 according to some info I got from another poster is Virgin Peak (which appears to have a site name of Angels Peak in the FCC listing - both names are present). Site 11's frequency seems to match Blue Diamond.

Has anyone thought of making a map in Google Maps Engine yet? I did that for my province-wide system here in Alberta and it's relatively popular.

 

[Dick33]

The Sunrise SY channel should be correct for that site. The other 2 freqs. are not correct, just temporary YG channels. There is already a map of the 9 simulcast sites here in the town.

 

[Jay911]

More sites are reporting in..

The simulcast site is now a neighbor of site 2, and as of sometime today site 3 went active.

Site 2 has the following properties:

The following freqs are Phase I (FDMA):
772.08125
772.73125
772.98125
773.49375
773.93125
773.99375
774.23125
774.59375
774.91875

772.73125 also indicated TDMA (Phase II) capability once and only once, but only the first slot was in use.

There were data (non-voice) talkgroup grants for TG 10016, 10010, and 10063.

772.08125 is used as the CWID (morse identifier), WQTF422.

As for Site 3:

001-003
Control Channel 774.46875

That frequency is licensed to Apex Peak, along with:
773.19375
773.48125
773.74375
774.19375

However, the site, when run through PRO96COM, brings up the following alt CCs:

773.74375
774.19375
774.84375

question

does anyone know the type and model of radios that metro uses in the car and hand-held devices?

 

[Dick33]

2900 APX6000 700/800mhz portables
100 APX7000 7-8/VHF portables
2900 APX6500 700/800mhz mobiles
100 APX7500 7-8/VHF mobiles

Don't hold me to those numbers but close

774.7437

band plan
0=851.00625/6.25
1=762.00625/6.25

Don't let the Uniden haters hear you.

 

[Thunderknight]

There are about 3 recent threads about this system, plus some older ones. Perhaps a single "sticky" thread for discussing the new Metro P25 system would be a good idea?

Um, it's not Broken Sky, that is why it sounds good.

There's going to be a huge learning curve when people don't have to repee-e-e-e-e-e-e-e-a-a-a-a-*

Sorry. I mean, don't have to repeat themselves 47 times because they "went digital". The coverage from even the small handful of towers that were active when I was in town at the start of the month seemed great.. hard to have anyone on the fringes the way it's been laid out.

Productivity is going to go up because officers won't be spending excessive amounts of time trying to get their radios to work.

Broken / OpenSky does not sound that bad as they make it out to be. . Listening to the patching of OS to the 700 MHZ P25 test system, it actually sounds pretty good, you really get a sense of what OS sound like. yes you do have those hanging jittery ending of the odd transmission, not as many repeats as you would think there would be.

 

[coolrich55]

Well no matter how bad or not so bad it is, still millions of dollars down the drain.

TDMA is TDMA.

It's not garbled radio traffic that is the problem. Typically, when the transmission goes through, it sounds fine. The problem is that some transmissions never make it, just disappearing into thin air, and officers often get denial tones when they try to key their mic, forcing them to walk around like some old cell phone commercial.

It's taken 6+ years, millions of dollars over the original cost, and numerous software updates to get to this subpar level. By now, it should be five nines perfect.

Two-and-a-half years ago, while listening to the patches to the old VHF I was surprised they managed to get much done. It seemed like every fourth or fifth voice call needed a partial or full repeat because the traffic broke into that nonsensical "da da da da", OR the transmission (for lack of better words) slurred at various points just enough to make it useless. The slurring wound like "Copy 467 on Nevada sluuurrrr six john adam baker, blue (whatever vehicle) Spring Mountain sluuurrr ound, East of Raislurrrow"

I honestly don't know the procedures and mental acuity of police dispatchers, but watching other types of dispatch, I get the impression that they learn to very quickly to type in each letter as being said phonetically and develop a very efficient flow that gets disrupted when they have to stop and 'think' about what they heard. I'm also guessing that each officer began to incorporate this unreliability into their process by delaying their next step in case they had to retransmit everything again.

Has anyone else noticed in the last few days that Metro is using CCSD Southwest School Police frequency? Or am I hearing things. I have heard dispatch call it from Enterprise AC.

Ever listen to NYPD? Can you imagine if they ever went with opensky and had these problems? Those dispatchers would go completely bonkers lol.
