Jerry,
It sounds like your ground system is shorting out your mast and antenna's. Myself, I wouldn't worry about grounding it. But that is up to you. I have the BCD325P2 and I work in Malvern. I pick up East Central no problem, but of course nothing for West.

You have to consider, that most 700-800 MHZ radio's transmit at extremely low power 5 to 10 watts at the most. Plus, Chester County has a lot of low spots. They had that problem with the LTR System from EF Johnson. It was so bad that they had to re-broadcast the transmissions on a VHF frequency so the Police and Fire could receive Dispatch.

The only way that these systems work is thru repeaters. But, If they don't have the power turned up for the repeater, you will not receive them. Plus, it's like Bucks County. They don't really want people from other counties receiving their broadcasts. They will tell you we are not encrypting (Except for certain channels) but the wattage is so low, good luck in receiving it. For me to receive both Bucks and Chester I would have to have 2 different scanners and 2 directional antenna's.

I have a 50 foot tower because I am an Amateur Radio Operator. But as long as I can pick up Montgomery County from where I live, that is sufficient to me. I hate to say it, but Motorola and all these other 800 MHZ manufacturer's have sold the police agencies nothing more than a piece of crap! They can't copy dispatch and they can't copy car to car. So what is the benefit? They were better using the old VHF and UHF frequencies that they had. The power was higher and communication was much more reliable.

You might want to get a Ham to come and take a good look at your grounding situation. He may be able to see where the problem is. Mark Griffin, KB3Z

Hello Group,
I just bought a 996P2 and for the life of me cannot decode anything…Shows that it is tracking, used everything from a stubby to attic antennas. Drove miles away in the car…nadda. Entered proper re-band tables.

I have been working my way thru the decoding thresholds.

Any ideas 996P2 owners?

How does it do on conventional signals?? If they boom in strongly at least you know it's not a bad solder at the antenna connector or something similar. Also Attenuator off of course?

Hey not to wake up old threads but at this point are all talkgroups on the Chester County system transmitting in Phase 2 TDMA?

Has any one noticed a recent change in the quality and volume of the transmissions in chester county? it seems to be a lower volume and worse quality of the transmissions. Also, I used RR to reprogram a bcd325p2 scanner using output frequencies. Do I need to program the input frequencies too?

No need for input frequencies - you only need to program the system as a P25 trunk system. Quality of transmissions likely has to do with LSM since this is a simulcast system.

Jerry,

Let's be careful here on what your telling another person on here. Grounding an antenna mast is a life safety issue and covered by the "National Electrical Code". In many cases your home owners insurance also has a strong influence on what you do.

The way the person described what he did to ground his antenna mast is the correct way of doing it. If you take a lightning strike and the house sustains damage, if the insurance company finds the antenna system was not grounded correctly, they could refuse to pay the damages.

First thanks to all on here who posted all the information on this system. The harris presentation definitely gave me the opportunity to wrap my head around this system. I've been listening since Friday with a 436.While listening last night I noticed that the system seemed pretty "quiet" I wasn't getting any traffic on any of the municipal police talkgroups which I found odd. Did a threshold adjustment 7 and set the squelch to 1 and boom. Enjoying listening to county somethings surprise me it seems Central Dispatch is busier than West. I would have never bet on that.

New TG Series coming online

Looks like a new series of TG's is being used by Municipalities in addition to the posted Municipal TG's currently in the 4600's.

today I received a TG 6660 with id's belonging to New Garden Twp PW 6004550-56

Can one of you kind local Chester County people please confirm the information in the first post of this thread?

Code:
851.6125
SysID: 00A
WACN: 92466
Site RFSSID: 010
Site ID: 010
Site NAC: 010

Is this accurate? RRDB says differently for the 800MHZ site in the CCES system.
https://www.radioreference.com/apps/db/?sid=7690

Which is correct? 851.0625c or 851.6125c

For what it's worth I'm using OP25 and can get the 769MHz (The WEST site) to scan and decode properly. But, no matter what I do I can't get the EAST CENTRAL site to scan and decode.

Apparently they have the same NAC but only different site IDs (as I understand it - but I'm new to this). And the software is only unique by NAC, and not by the NAC/Site combination.

If any of you are using OP25 to successfully listen to BOTH site, could you please share your rx config and trunk.tsv files. I've been at this for days and can't make it work.

Jerry, perhaps you know?

THANK YOU!

I was sure where to post this, so I figured I would start here, since I didn't see a strict paging thread. If I'm wrong, please feel free to move to the right place/thread.

I was traveling through the county on 1/24/18 to see family and I had my VHF Minitor 6 along. I could of sworn I heard a new tone for "Medic 55/ALS" but I could be wrong. If a new tone was created, does anyone have it so I can add it to my tone list?

Thanks in advance!

I've been able to successfully listen to the east/central site from Tredyffrin, but never even attempted the west site. My RPi is at home right now, but if you want the trunk.tsv I can get it to you tomorrow (I know it's not what you asked for, though). Good luck.

It wasn't just created, it's been in reserve since the system was implemented years ago, just only started being used when they added ALS service.

Download the tone list from the wiki page. It's listed there.
