Paging

Yes, the paging will be on 460..0375 using Posag format, 512 bit.

Last month there was many test pages sent but I have not seen
any actual dispatch pages yet....

I don't know if the pagers have been distributed to field users yet.

Update 12/26/15

System up-date 12/26

Very slow adding mobiles, especially on the fire side. Most
police and EMS units now have mobiles. I think completion will be months
at this rate of deployment.

Almost passed out this morning when I saw a local police
car in the parking lot. The 800 Mhz, 1/4 whip is mounted
on a lip bracket on the trunk. The former VHF-L NMO hole in
the center of the roof now has a rubber plug. "Gotta be kidding"

This system has great coverage but the audio stinks. Most of us
locals have dubbed it the "Soup can" after the soup can with a
string stretched between. The audio has no lows and very few
mid range components. It sounds that way on my scanners and a
hand held operating on the system.

Multiple patches and straps are still in place, but the audio
is so poor, most are unusable.

More testing this week on the new paging frequency. The simulcast
distortion is severe in many areas and sounds like it could be
a big problem. They have a CW id'er every half hour but the distortion
is so severe that I have yet to hear a clear, undistorted id from
multiple locations. Unknown if any new pagers have been issued yet.

Many radio's still inactive or missing from the list of users.

Updating the TG list has been slow and difficult.
Many end users still wondering all over the place while exploring
their new toys and many having problems adjusting to the talk group
mode of operation.

Gettysburg Hospital has been on from the start and receiving info
from in bound ambulances. I have yet to hear Hanover Hospital
on the system. Their radio ID, 346001 and 346002 shows up everyday
on Unitrunker but is always rejected by the system. This has been occurring
for over two weeks and still not operational.

More excitement later

I can confirm that pagers are slow to be pushed. If they did push some it would be maybe the Chiefs, Dispatchers (Supervisors), and maybe County EMA. If regular Dispatchers had them, County wouldn't have used the LB for the ones they paged the other day.

Adams County Fire Broadcastify feed

I see a couple of posts about the feed for Adams County. I am the feed provider for "Adams County Fire" and now have a Whistler 1095. I need to put up a new antenna and program the radio, but hope to have the feed converted over very soon. Until then, the low band feed is still up. Some of the information I have on the system is already obsolete, so I need a reliable source for the system configuration. More to come! (I am a firefighter with Alpha in Littlestown, and have a vested interest in keeping it up. :wink:)

From Littlestown, you shouldn't have too many issues receiving the "east" site with the stock antenna. There's a tower/site just west of town near Fish and Game...

You might need something a bit better to get a good signal for the "west" site.

I've played with it a bit, but think I have some bad information with the setup as it is not receiving anything. For the low band, I put a 6 meter antenna on the roof. I plan to have at least a "very good" feed, so a discone or SMR is soon to join it!

What info are you looking for ? The list in the RRDB is correct and works fine on my 1095. I'am
using a paper clip for the antenna and works great since I'm only 3 blocks from the court house.
You are not much farther from the Littlestown tower so a very minimal antenna should work.

Leave me know if I can help.....

Thanks W3DMV, I am traveling for the holidays so it will have to wait until I get back. Knowing the the database entry is correct helps. Not sure what was going on when I first loaded it, though.

The RRDB for the Adams County System is fairly accurate as far as the TG's go just have to make sure the system you have setup is set to P25 Phase II and have the right control frequencies in order to receive the transmissions. I'm less then 200 ft from the Court House and was picking up stuff with no antenna when I was switching over and installing the new antenna. The Terrawave T09150Y11206T 824-960 MHz 15 dBi Yagi is so good that I'm getting the Frederick transmissions on their new P25.

So will the voice paging be discontinued here as well in favor of alpha paging? This is a sad trend in that part of the state. Hopefully the trend goes away as quickly as it started and everyone goes back on voice paging ASAP. Should just move the current voice paging up to UHF like Franklin uses and drop the alpha paging.
*sighs*

A rooftop antenna with P25 Simulcast is going to have some big problems. Not sure if you all know about P25 Simulcast Distortion. Simulcast digital distortion - The RadioReference Wiki

Almost all the P25 systems in the DC area will have the Simulcast Distortion problem with normal antenna's.
I notice it more often when I am driving around with a handheld scanner.

As long as you get a fair to good signal everything will be crystal clear digital P25. A directional antenna will help with distortion.

Codes

I'm not sure the codes have been selected yet. County has been unwilling to
provide any information regarding talk groups or paging codes. I've requested
them several times and was turned down...

There has been some intermittent paging testing over the past several months
but no incident pages that I've seen. I have a decoding set up running 24/7 and
nothing noted.

If nothing else, I will decode when they start using the sites and post the results
which might be hard to accomplish since they have a major simulcast distortion
problem...

Cap Codes

I knew things would change after making the statement regarding codes
yesterday. Some activity started today and seems to be limited to mostly
EMS units. Attached is a list decoded so far. Will update as more become
available...

Little Help

Been working hard to fill in the blanks regarding talk groups
and pager addresses.
Unfortunately many local governments don't have radio's yet or
didn't use them during the big snow storm so the list is still
missing many users.
One of my blanks involves the id of several med units that are
active but I'v been unable to label. Perhaps some of you east
side guys can help.

Radio ID User

328 Gettysburg Hospital (Using old Co 28 which makes sense)

346 Never understood the Hanover area stuff. I always associated
46 units with the Hanover fire/ambulance crews. Radio ID 346
is being used by Hanover Hospital. Is 46 shared by both the
hospital and the Hanover boro units ?

351 This unit makes many runs in the southeast area of the
county and id's as medic 51. Anyone know who this one
belongs to ? (No station 51 on my York Co list)

352 This unit makes many runs in the southeast area of the
county and id's as medic 52. Is this a York County station
52 (Pleasant Hill) unit or other ?

----

The new paging system is slowly coming to life and cap codes are
added to the list attached. Most follow a assumed pattern and are
not difficult to identify.
One of the odd ones that shows up is code "0631037, 0631038, 0631039
which county has labeled as "EMA31 Van". Paged out for the Brethern
Home fire and the fatal in Littlestown last night. For what ever
reason, the label is the same but it has three different cap codes ?
Any help would be appreciated..

If anyone would like to put the pager list in the "Wiki", please
help yourself. I never figured out how to do that !

I was about to post this info below but then I id a quick check and found this

At least when I lived in southern Hanover 20+ years ago, Medic 46 ran out of Hanover Hospital and was separate from Hanover Fire (station 46).

York Station 51 (20+ years ago) was (I believe) Grangeville (Penn Township) which is now part of Station 49 I believe.
