Asbury Park Upgrading Fd Radio Systems

[KEVINOBRIEN6905]

NO TIME FRAME/UPGRADING TO A NEW 4 STATION DISPATCH CENTER AND AN apco25 DIGITAL RADIO SYSTEM. FD NEW PRIMARY FIREGROUND CH WILL BE DIGITAL THIS WILL BE KNOWN AS TAC 1, RX 151.1675 TX 156.2325 DPL 331 WILL ONLY BE FUNCTIONAL ON DIGITAL SYSTEMS. COUNTY WILL BE ABLE TO HEAR TRANSMISSIONS BUT WILL NOT BE ABLE TO TRANSMIT UNLESS COUNTY RADIO IS DIGITAL. THEY WILL MAINTAIN CURRENT ANALOG CHANNELS OF DISPATCH, AND TAC 2 MONMOUTH FIRE 7 153.830 151.4. THE NEW TAC 1 WILL BE A REPEATERCHANNEL WITH 4 RECEIVER SITES LOCATED THRUOUT ASBURY PARK TO IMPROVE RECEPTION. THIS APPARANTLY IS A FIREGROUND ONLY CHANNEL AND WOULD SEEM TO BE THE ONLY DIGITAL CHANNEL(AT LEAST FOR NOW??) AGAIN NO TARGET DATE ON THE MEMO FROM ASB PK FD. KEVIN O'BRIEN

They really need Apco 25 Digital for the FD? Asbury Park could spend its money in many more areas than this. First the PD with their encryption, which I understand in a place like Asbury Park (as opposed to Pt. Pleasant), but this seems unnecessary.

pal, get used to it.i believe the fcc mandated by somewhere around the year 2015 all public safety will need to be digital.this is partially for the need for bandwith space.

OK, turn the CAPS LOCK off next time, please...

Point Pleasant is digital???? When did that happen??????

Thanks for the update!

Yikes!.........digital on fireground? Guess they didn't read about the trouble the FDNY had.

And yes there is a an FCC mandate.....that they keep pushing ahead. (Was originally 2013) But it doesn't mandate digital systems.....it can be any spectrum efficient technology.

Point Pleasant BEACH is digital (police only), been digital for quite some time. Point BOROUGH is analog.

DJ88,

Thank you for the correction on that. You always post "accurately" on the board and it is appreciated.

No. The FCC has never mandated that everyone become digital.

The mandate is that, by January 1, 2013, all Part 90 users - with the exception of a handful of paging channels that are mostly used in hospital paging (most alert paging channels still have to be narrowbanded) - shall reduce their emissions to 1 voice path or 9.6 kbps data within a 12.5 kHz channelspace. This is STILL inadequate for effective adjacent channel separation on the 7.5 kHz VHF channels, btw.

After January 1, 2011, Part 90 users will not be allowed expand or modify their wideband radio systems, or license new wideband systems.

It's not clear yet whether the enforcement of this migration to narrowband will be an active process (i.e., FCC enforcement bureau agent and Deputy U.S. Marshall show up at your door and pull the plug, literally) or passive process where wideband becomes secondary and enforcement will only happen if someone complains.

There are narrowband analog options, but generally going digital recovers range that is lost from the reduction in intelligibility going from 20K0F3E down to 11K2F3E modulation. Many analog systems will have to be reengineered at the time they narrowband, especially if they use synchronous simulcast.

To add to the information 902 posted, I googled FCC Public Safety Radio Mandates and came up with this, which explains the narrowband requirements.

Does this mandate include newly licensed systems?
