Lancaster County Dumps - MA/COM OpenSky System

So a York County unit who will only be accessing fire talk groups (none of which are using encryption, there-by not needing re-keying) should be able to access the system without issue.

Moto's ability to clear the emergency without any dispatcher input was viewed as an officer safety issue..

York has always allowed and WELCOMED P25 radios from other manufactures..

I personally view the dispatcher's ability to clear my radio's emergency status without MY input as MORE of an officer safety issue.

Truth be told, on a Moto system, BOTH the dispatcher AND the user must clear the emergency status to fully reset the emergency. If only the user, but not the dispatcher, clears the emergency, the talk group still remains in emergency status. If the dispatcher clears the emergency, but the user does not clear his radio, as soon as the user re-keys again, the emergency is sent again. Redundancy and redundancy are good.

Apparently the comm director has a reason for his policies..

As for the console, You saw Baltimore County's set up but there are MANY different config's available to set how an emergency is handled.. York prefers and uses the dispatcher reset as their standard.. Once again, MOTO tried to change the world to their way and the rest of the field went with the P25 standard.. It's a shame Phil pass away as he was the only KNOWLEDGEABLE one in the Davies drive building.. He passed and Julio folded..

But either way... A Motorola, Kenwood or whom evers P25 radio will work just fine on the York Harris system..

Is the pilot system for Lancaster City currently being built? How are things progressing?

[NodrogCop]

As of this week, the contract had not been signed. I've heard that it's due to minor issues and is to be signed soon, with the small test system in the Lancaster city area to be done late fall/early winter.

If all goes well, they could be loading users early next year.

[Tom_Pa]

Thanks for the info. I hope things go well for them this time.

Is there any information on what they are setting up for a "test system"?

Don't know exactly. I don't think they're going to be loading users. Maybe just testing coverage and features with techs? That's a total guess on my part.

Totally incorrect. Motorola uses P25 standard OTAR (rekeying). This is for encryption. All other current P25 radios work with Motorola OTAR. System key has nothing to do with OTAR.

Either lies by Dave Murdoch or you misuderstood what his is talking about.

Quick question for everyone. Let’s say I’m a student in Lancaster County and I have been spending a lot of time with Lancaster EMS (LEMSA). I notice the have a different or additional radio system compared to the rest of the county units. In the trucks themselves they have the county low band but they have an additional Motorola radio that appears to be digital in nature. (I’m from York Co. so the delay and the digital errors are similar with their radios ars are ours.) So here is my question. Are the LEMSA radios on a digital trunked system? If so does anyone have any idea of the Freq’s or ID’s?
I asked on this forum because I thought it may also be from the system LCWC got rid of.
Any help would be appreciated.

LEMSA has had their own private VHF channels for some time. In the past, it seemed that county would tone a 612 unit, then LEMSA would re-dispatch that unit on their private channel. Also, I believe that LEMSA does (or had in the past) called in patient reports on their private frequency. The LEMSA comm center is (or was) located at LGH. I never knew them to be digital, but that could have changed.

Someone has told me about this before and if I recall correctly, they are using an LTR Standard system, but it is NOT their own. They have permission to use it. I am not sure if that is the case though. Someone did have awhile ago a hand held radio that had a full key pad on it, and i don't think it was low band

[Tommahawk]

Its not a trunked system that LEMSA has. It's a vhf repeater that LEMSA uses to talk to units in the field...

155.4075 with a DPL/DCS tone of 025. Input Freuquency is 150.7975, same DPL of 025. Their other frequencies in the UHF band are being terminated because they are not Narrowband... The repeater that LEMSA uses is connected via IP address,and that is the reason for the delay, sorta kinda like SKYPE

FCC Licensee Callsign: WPQK401

Drumore Township expects to purchase all new radio equipment by 2014 or face an essentially defunct system.

Township supervisors said they were not pleased with the situation when they discussed it at the board meeting Thursday because they paid for new radios at the behest of the county only a few years ago. The radios are used in public-safety and maintenance vehicles. Lancaster County is now in the process of switching over to a television communications band for its public-safety radio system, which will make new equipment essential

Lancaster EMS has switched to a MOTOTRBO uhf system. I think the main tower site is on LRMC and one or two others in the out lying areas. It is also crossbanded to the counties low band radio system.

Reference LEMSA..

Here is the latest letter from the FCC...

No one can pick up their system correct?

[lancopa]

Anyone find any new things out? The radios are installed in some of the units already and no one posts no info? Like if they are staying Phase 1, or end up going Phase 2. Will the system be open, fully encrypted, or somewhat encrypted for SWAT, NARC etc. We can't be this far into the system and no one knows nothing about it.

Doesn't Lancaster City PD start testing?

[lancopa]

Can anyone pick up the new LEMSA system?

Also I take it that there are no updates for the county?

[lancopa]

Does anyone know if the city PD started their trial?

I don't think anyone is testing anything yet. Lanco had the original contract amended to facilitate some technical changes.
