Yeah, I sat down just in time to hear the police involved shooting. It appeared that they had East-1 and J Band patched together on both systems for awhile there.

I've confirmed that TG 335 is Sheriff Dispatch and 313 is Water Dept Dispatch, both carried on zone 1

phillydjdan,
i spied your shack pix,
what are you running for
antenna's,,and is that
IRON threaded pipe as
a mount/weight?

Funny,,from the rooftops,
our houses/neighborhoods
look almost the same,,

Yes, sir, that is threaded iron pipe. It is not attached to the roof in any way, and it never moved an inch during the hurricane. I couldnt believe it. The larger antenna is i think a tram dual band that i got off fleabay. The smaller antenna is a high gain uhf antenna that i also got off fleabay. I dont use either to receive philly, though (dont need to). The dual band feeds a duplexer, then into the mcs-2000 rigs. The uhf feeds the pro-197 and my vhf feed radio for bucks fire.

back to more radio testing,,hearing mixed clear and encrypted radio checks..

Hummm, I reloaded the new system this morning to pick up the tags that have been added so far and I didn't hear a thing all day on there.

If you didn't add a "wildcard" to your scan list, or if the TG's they were testing were the "specialty ones", you won't hear anything. Those special ones are not listed in the RR database because of the encryption. Based on what horseman said earlier about some comms being encrypted, I would venture a guess that they were testing the specialty channels. I will check my recordings in a little while and post my findings.

fourthhorseman · #48 (**permalink**) 11-15-2012, 5:33 PM

Also,i originally used the import feature for the 800 to add the system,
it loaded default tables,i had to manually enter the custom tables,just as
its in the RRpage..1st set as P1FDMA,,2dn set as X2TDMA..came online
right away,,

these are a quick list i jotted down of some radio checks i caught today..
scanning both zones..not sure who was on what...
249-enc
245-enc
247-enc
255-n tac 2?
257-n tac 3?
267-enc
407-clear&unk
409-all south
411-clear&unk
251-clear&unk

My recordings show lots of activity on the North and South Tac bands on the old system. Some other activity also on most of the other listed talkgroups, as well as some unlisted ones on the new system. According to my mapping of the new system:

245 is South Tac 1
247 is South Tac 2
249 is South Tac 3
251 is Fire Admin
253 is North Tac 1
255 is North Tac 2
257 is North Tac 3
267 is Hazmat Ops
407 is South Fire Alt
409 is North Fire Alt
411 is South Medic Alt
413 is North Medic Alt
415 is Medic 3 Alt (formerly called Central Medic)

The Tac channels, Hazmat, etc are supposed to be encrypted, which would be why byker didnt hear them. The Alt & Admin channels can be either, I guess.

I could e-mail anyone who is interested a complete list of old and new talkgroups in an Excel spreadsheet. PM me if interested.

I always make sure to have the wildcards checked. I wasn't listening solely to the new system I had my normal stuff running as well on my pro-197, but I did the same yesterday and was able to hear the radio checks fairly often. The only difference is I deleted and re-installed the P25 new system so the "notes" would show on the scanner..

phillydjdan · #51 (**permalink**) 11-15-2012, 6:04 PM

That's weird, Byker. I had to reprogram my entire PSR-800 over the weekend (SD cards should never have been integrated into a scanner, but anyway...) and I am picking up the system just fine with the channel names and all. I didn't have to change any settings or anything. You know, I haven't tried programming the new system into my Pro-197. Do I have to do those custom tables for that scanner?

soberbyker · #52 (**permalink**) 11-15-2012, 6:27 PM

I'm not sure. I know I downloaded the new P25 system awhile back when it first posted and up until yesterday I was doing fine picking up the various tests. I saw new "info" added when I checked it on RR this morning so I downloaded the "new' version and didn't hear a thing all day.

I use WIN500 to transfer the file from RR, I'm guessing I took the correct file

Philadelphia (Project 25) Trunking System, Philadelphia, Pennsylvania - Scanner Frequencies

I don't really tweak much other than LED color and whether or not they flash.

rgchristy · #53 (**permalink**) 11-15-2012, 11:20 PM

I wasn't picking up anything either, until I realized that I have a better signal with the old system than I do with the new system. I thought it would be the opposite, but I guess not. I'm able to pick up the old system with my 800 sitting on my kitchen table in Springfield with just my RS 800 MHz antenna. No such luck with the new system.

Anyway, I've read through the entire post and I still can't figure out a few things. How did you separate the zones? Did you have to create two systems manually? I tried to delete one of the zones and then do a library import to add the second zone with another set of the talkgroups on a different scanlist and all it did was add the second zone to the existing system, so I guess I'm not doing that correctly. Also, when I import the system, the trunking tables show as "Auto Fill". The custom table is there and correct, so do I then need to select "Custom" and then "Apply to All Sites" to activate the custom table?

One other thing that I didn't realize is that with the exception of the Phase II talkgroups, I could listen to the system on my 500. Is this correct? If so, I'll have to check it out.

Thanks guys for the great info on the new system.

Take Care,

Rich C

Also, I forgot to ask what you have the Data Decode Thresholds set at and are there any other settings that you change?

phillydjdan · #54 (**permalink**) 11-16-2012, 5:48 AM

Rich,

With my PSR-800 I did a library import twice, each time selecting only the zone I wanted on the system. I then changed the labels to Philly P25 Zn 1 and Philly P25 Zn 2 for each scan list. I imported all known talkgroups into both scan lists, since I know that sometimes certain channels (J Band, for instance) are carried on both zones, then added a "wildcard" on each zone.

I'm not sure what would cause a difference in reception as you are experiencing. I know the designers of the old system, did things weird and made the antennas favor radiating in towards the city. I know with my Pro-96 (primarily used in the car) I have to put the attenuator on inside the city, but even with the attenuator off I lose it within a few miles of the city line.

fourthhorseman · #55 (**permalink**) 11-16-2012, 6:46 AM

system importing..
i imported the system,,modified the table,then duplicated the system,,then deleted Zone2 on the first,
and Zone1 on the second..presto...had that same frustration with the EZ software being a lil dumb in that respect..

DJDAN
Outstanding work on that/those lists..you been diligent,,and busy!..Thank You!

Poor Signal..
wondering if the new system will be a more directed signal.focused into philly..

Horseman, i actually had the more comprehensive list of the old system for years, and always enjoy listening to the undercover ops

Once they started patching i was able to look at the new system i figure out that the channel mapping is the same pattern, just spaced differently. Then i created that spreadsheet to visualize it. It looks much easier to interpret and understand it when its arranged like that. And now you can manually enter those talgroups and know exactly what channel is what, with a few exceptions. I dont know where they are gonna put the ppa talkgroups.

yes,yes..ive got that,, i guess we can soon call it -legacy- info too..

still great work man..ive been trying to figure out a way,,TO figure out
the new order..was feeling like learning to walk again..lol..

rgchristy · #59 (**permalink**) 11-16-2012, 7:33 AM

I just deleted and reloaded the system. This time the custom table is not there. I'm entering the custom table and have a few questions. I'm guessing that "Type" = "Slots" and if so, does "FDMA" = "P1FDMA"? Also, does "TDMA-2" = "X2 TDMA" or "PII TDMA"? After this, just apply the custom table to all sites? Then I'm going to try the duplicate system trick since importing the system twice didn't work for me.

Thanks,

Rich C

P.S. I also just noticed that when you click on "Apply to All Sites" after creating the custom table, it doesn't apply it to all sites. Is this normal? I created it in zone 1 and after applying, zone 2 was still empty under custom.

The tables should be set to auto for this system; no custom tables are necessary...
