Anybody recognize this system? I just found it doing a search on antennasearch.com of my area.

WPAP561 (BERGEN, COUNTY OF) FCC Callsign Details
On these old 800 MHz MDT channels now used as back up as reported. Any idea of the PL, DPL or NAC used? If known please post and submitt to DB. ThanksIt's a backup system, just like 155.5500 and 477.2875 are still analogf

MDT = Mobile Data Terminal. There is no PL/DPL/NAC, the transmissions are a stream of data.
IF this frequency is still active (no confirmation as of yet), then it would go into the database as: Type BM, Mode Telm, Service Tag of Data, and the tone field is left blank.
I find it dubious that there is a "backup" MDT channel, as that would require the old modems to still be installed in the vehicles. Chances are they simply continue to renew the license because it's free and public safety rarely gets called out by the FCC for non-usage of dormant frequencies. Why give up a potentially valuable resource, like an 800 MHz frequency in the NYC metro area, if no one forces you to?
I have it listed now as a back up / inter ops for the county.
I can verify the county does maintain a repeater system (analog) on the listed VHF and UHF frequencies for inter-ops and patching to the trunk system monitoring activity myself hearing radio traffic on them.So, we're to believe that a county that is entirely VHF and UHF (including a countywide T-Band trunked system) maintains backup channels on 800 MHz? :roll:
Again, highly dubious, especially when basing it on of an off-the-cuff post by someone who now lives in Cape May (and who doesn't even have these frequencies listed on his own BergenScanner.com website, no less).
Arbitrarily adding things to the database that have no basis in fact is how useless junk accumulates over the years. :wink:
that old MDT system i thought was turn off 10 years ago when they went to laptops/verizon cellular?
i haven't heard anything on the freq's for very long time - some how the license gets renewed like the low band channels that the county does not use/have ?

VHF and UHF backup and patches, yes. 800 MHz backup? Doubtful.
Adding unconfirmed frequencies to the database is not in line with RR policy.
Having "backup frequencies" in today's high-tech radio environment makes as much sense as a police department having a "backup" of six-shooters in case the semi-autos don't work anymore...
No one takes a step backwards anymore. Motorola makes sure of that!
Not having local knowledge of the system, makes this purely speculation.
Respectfully, you're on the other side of the continent, so I'm not sure why you'd be weighing in on a local issue that you freely admit you have no knowledge of.
Having "backup frequencies" in today's high-tech radio environment makes as much sense as a police department having a "backup" of six-shooters in case the semi-autos don't work anymore, or an FD having a truck with wooden ladders in case a Tower Ladder breaks down.
Even though they keep these frequencies, I would question if anyone in Bergen County government knows for a fact that there are a cache of radios (without an inch of dust on them) to work on those frequencies if they needed this "backup." I doubt it very much.
