Philly 800mhz System Status

I work for a city agency, and we received an email from our radio people that our existing portables/mobiles are being upgraded during the remainder of the month of October with the new frequencies/talkgroups. Deadline is November 15th, with an expected cutover to the new system in January 2013.

Haven't seen too much about this lately, so figured I would chime in what I've heard.

will the police talk groups be in the clear? And fire,Public works and all

captaincab 10-14-2012 12:09 PM

the same groups that are encrypted now will stay encrypted but no other new ones as far as i know and the ppa will be moving to the new system however i have it on good authority things may change for the better for all us scanner listeners in the near future.

alrighty thanks 4 the info that sounds like good news and that's awesome that the ppa is going on the new system.

I agree, haven't seen or heard anything to suggest anything will change with regard to encryption, at least in the near future.

Philly System
Will the Uniden 996t, 396xt, home patrol support the new system?

Looks like the new set up will be the P25 Phase II
Philadelphia (Project 25) Trunking System, Philadelphia, Pennsylvania - Scanner Frequencies

GREs 800 seems to be the only radio moving in that direction..

Is there much activity on the new system? Are the patched talkgroups from the old system regularly active on the new system? If not, at what times will they be patched over. Has anyone heard anything on the system with their PSR 800?

Whats up with the new Freq's with TONE "N-CAD NAC" what does the "N" stand for?

I've heard it on my PSR-800. The patched channels are sporadic, and might not even be taking place anymore. They would do one or two at a time for a couple days mostly during the daytime, then shut them off again. I have not given it a listen lately, though. Guess I should huh? lol I'm seeing a lot of talk about tables, is there anything I need to change for the Philly P25 system since I did the upgrade?

Those are the simplex tactical freqs. The NAC Code is CAD. I know when my Pro 106 displays a NAC it displays as N-XXX.

Thanks Joe, I use Uniden. And they dont show it that way.

Ive noticed it too..or noticed the absence of traffic..

there is alot of radio testing going on all over the city,
and on a sp-ops band...lots of testing of portables..and
lots of radio checks by district dispatchers of the
-Back Up- system..

way more than usual,and more frequent than anything ive
heard in a few years.

Yeah, ive been hearing radio maint doing radio checks on the fire bands, asking for the radio alias and testing the emergency open mic, etc. Sounds like they are programming the new radios to work on both systems so they can be deployed before the switchover. I have to go back and check my recordings on the psr800 and see if there has been any actvity.

fourthhorseman 10-20-2012 8:33 PM

yeah,,was curious if its been occurring on the fire side..same tech,,testing,,12345..testing...
then to the next radio..repetitive..but good light cardio..curling the portables all day..

phillydjdan 10-21-2012 12:49 PM

Yessir! I've been letting my PSR-800 run the new system all week, and not a peep, unless my settings are now incorrect with the firmware update.

fourthhorseman 10-21-2012 5:41 PM

Yes..thought that too after the in another thread about reverting the firmware..using the 1.6 will roll back the beta..

phillydjdan 10-21-2012 5:43 PM

I'm not clear on what you're saying. I SHOULD revert mine back? The update does nor does not change the settings required for the new system? Or am I good to go?

fourthhorseman 10-21-2012 7:44 PM

Not sure myself,the PPDs new system has been real quiet,but im not sure if its the update that altered the settings or if the new system is just idle..personally im glad to know the option is there to revert the firmware..just in case.

phillydjdan 10-21-2012 9:12 PM

Ok, gotcha. I will keep mine on both zones and recording, so I will report back if there is any activity on known TGs or wildcards.
