York County - HARRIS RF COM - p25 System

[ocguard]

If you have questions ASK.. WE HAVE NO SECRETS...

tgid list?

Hehe, just razzing ya mister radio system admin! I'm sure it's coming in due time.

As far as the background noise testing, It's not so much about volume as it is about about getting the right sound.

As many people who are familiar with digital voice modulation know, P25 vocoders are designed to encode human voice, which is extremely imperfect and has very few patterns, like mechanically and electronically generated noises do. Early generation P25 vocoders (Motorola Astro XTS3000), therefore, could not handle noise other than human voice very well, which is why when you hear an alert tone on a digital system, it sounds kind of "scary." The two most problematic sounds identified on fire ground causing trouble with vocoders are power saws (both rotary and chain-style) and PASS alarms. In some cases, these sounds "fight" with the vocoders so badly, that they are considered 100% background noise, and the radio won't carry any associated voice.

Radio engineers have done amazing things with improving vocoders to better handle these noises.

After Saturday's impromptu test, we should see how well the newest generation of P25 vocoders can handle these noises. I think we will be pleasantly surprised on how well it sounds!

Matt,
You looked over the entire fleetmap in my office.. Don't you remember them??...It is not a secret if it's hanging on the wall in plain view... It's just not being distributed to the masses ..

Correction....
Phil is the system admin.. He replaced Bob Bragg.. He handles the personel issues...

System Management... Technical issues is me...

Get it right !!!

I'll bring my camera phone Monday. But lets just say. I remembered what was important. You'll see on Monday.

System manager -- sorry -- I gave you a field promotion!

Lebanon City on handheld back to York on North system in vehicle.. l&C audio both ways...
Ran 501 from Lancaster (Rt30) to Hershey (we turned off 501 north of Lancaster and ran thru Lititz, Palmyra, Lebanon and Good old Annvile) All areas were Loud and Clear to York on the North system

 

[NodrogCop]

A dumb question, but... Is York City PD on the new trunked system as well? I looked but couldn't find an answer. I have several friends who may be hired there soon and they were curious.

Thanks and I apologize for the question in advance.

Yes there are TG for City PD on the new System.

Semi-related question - does York County DES handle the dispatching for York City PD/FD as Lancaster County does to Lancaster City PD/FD?

Yes. YCDES 911 dispatches ALL fire and police agencies in York County (including York City) with the exception of PSP.

If this hasn't been posted yet, York County now has an on-line CAD Incident Status page:

http://www.ycdes.org/webcad/

I'd say it's on par with Lancaster County's Incident Status page. Great job, YCDES!

Listen Saturday AM -- more background noise testing slated with power saws, PASS alarms, driving water, etc.

Keep in mind, this testing is being done by the County radio staff members, NOT M/A-Com. M/A-Com continues to do their coverage and contour testing, while the YCDES staff continues to do things to build confidence with the system.

As the system continues to be optimized, it continues ti impress even the M/A-Com technicians.

I have even head a report of a portable radio connecting to the system from the top side of the Baltimore Beltway!

We in York County continue to look forward to this huge improvement in public safety!

Any reports on how the testing went?

Rich,
Stop in and see me..

[policefreak]

So, does anyone know if there will be any encryption on the new system

 

[ctrabs74]

It was noted elsewhere in this thread that the bulk of all comms will be clear, however a few TGs will be enabled for encryption (ie. narcotics investigations, SWAT, etc).

 

[ocguard]

Talk groups added to the DB. Enjoy.

Update

Well the systems are all under test.. Coverage Bit Error testing is about 30% done with GREAT results... The north end of the county (From 30 to the county line on the east side).. Circuit Merit (can u hear me now) testing is slated to start VERY shortly !!.. The 100 buildings list is being complied and special request areas / buildings are being identified.. Paging coverage testing is slated to start Tuesday.. Turn your old EMA radio or scanner OFF as there will be a page being sent about every 6 seconds for a lot of days... Alot of noise !!!!!...

First interop gateway is in test between one of the old legacy systems and the Trunked system... Sounds good for being roughed in... This answered a BIG question as to how we would interop to say Lancaster on low band... Piece of cake !!!

Pager distro is just around the corner.. Couple of weeks !! just waiting on coverage tests to be complete..

Remember..... WAIT FOR THE BEEP !!!!

In a recent meeting of the York County Fire Chief's Association, York County Department of Emergency Services Executive Director Eric Bistline announced that transition to the new P25 radio system may be as late as the first quarter of 2009. Very disappointing, considering recent news that go-live may be as early as August. And on top of this, York County 911 had a brief but total failure of it's legacy radio systems early Wednesday morning during a major thunderstorm, and while a number of working fire incidents were occurring. Safety of the county's emergency responders is greatly compromised until a reliable communications system can be established.

Trunked audio

There are patches in place and active between legacy fire dispatch, 33.88, sheriff, Zones 1,2 ,3 4,5, Med 10 and city fire. Some may be inactive as other work is being done.

Coverage testing is done for Mobile and portable on street.. Looks like it will pan out to be 99.?? % mobile and 98.??% portable ON STREET.. In building is scheduled to start next week(?)..

Paging coverage testing is done.. Results to follow but looks like 99.??% on street.. Much better than we have ever had..

Kinda of unrelated but if someone could help me program my RS Pro-2052 for York Co. I would appreciate it i need the base freq. and offset if you want you can email me because i would really love to listen. I live In Lancaster around MT JOy If that info Helps

The RS PRO-2052 will not be able to Monitor or trunk the York County Digital p25 radio system.

You will need one of the following scanners:

GREcom PSR-500 or PSR-600 Digital Scanners

Uniden Bearcat BCD996T or BCD396T Digital Scanners

The RS PRO-96 / PRO-2096 Digital Scanners should also work, but there the out of date, older versions of the GRE PSR 500/600 and will not do a very good job.

 

[fireman8085]

so i guess those are the digital trunking scanners and are there any trunked frequencies the pro 2052 will handle at present time
