Nassau County Fire 46.100 crosspatch...

[APX8000]

Nassau County Fire...

Does anyone know where the 46.100 crosspatch on 458.3250 dpl 423 is located, who owns it and how the reception is around Nassau County ? I thought I heard Inwood previously.

Also, are there any other patches to 46.10 ? I know most departments simulcast their dispatches on their own UHF channel.

Have a look at this thread, http://www.radioreference.com/forums/showthread.php?t=59504&highlight=uhf

I can pick up the UHF xband signal all the way in Central Queens, but not a single word on low band.

Thanks for the link...

While I have some ears...I'm trying to decipher who dispatches who in Nassau. This is what I have so far for the 6th Battalion. Additions, corrections and other Battalions are encouraged.

6th Battalion
600 Bellmore - Dispatched by 650 on 46.10. Ops with 650 on 46.32. Also heard units calling 650 on the Bellmore repeater 453.7875R.
610 E Meadow - Dispatches themselves on 46.10/460.4375R. Ops on same channel. FG on 460.6250R.
620 Levittown - Dispatches themselves on 470.3000R. Ops on same channel.
630 Massapequa - Dispatches themselves on 470.5125R. Ops on same channel.
640 Merrick - Dispatched by 650 on 46.10. Ops with 650 on 46.32.
650 N Bellmore - Dispatches themselves on 453.8500R. Ops on same channel.
660 N Massapequa - Dispatched by 630 on 453.4125R. Ops on same channel.
670 N Merrick - Dispatched by 650 on 46.10. Ops with 650 on 46.320.
680 Seaford - Dispatched by 690 on 46.10/458.2875R. Ops on 458.2875R.
690 Wantagh - Dispatches themselves on 471.3125R. Unknown if simulcated on 46.10.

46.10/fire comm nassau

Has anyone besides me noticed a significant drop in signal strenghth with 46.10?? Or when a department tones out there is too long a delay in the dispatchers voice coming across and the scanner continues to scan,missing the call??!!

To answer the crossband stuff, here is my list of locations:

0458.3250 - 46.10 X-Band rptr - dpl 423
0458.2750 - 46.32 x-band rptr (Roosevelt) - dpl 546
0453.0875 - 46.12 x-band rptr (Roslyn) - dpl 423
0453.9875 - 46.20 x-band rptr (E.Rockwy) - dpl 423
A quick FCC lookup shows the 46.10 repeater to be in East Meadow at 2201 HEMPSTEAD TPK. Also, there is an East Hills location as well..operating under the call of KNFL934


As far as the delay between tones and voice on 46.10.. I have noticed that when some departments are toned out that there is a delay. I haven't noticed this for ALL departments being toned out on 46.10 though.

And e911god.. Your list looks pretty good.
I am almost 100% positive that Wantagh does not use 46.10 at all for dispatch. I don't remember hearing them on 46.10
I am also thinking that E. Meadow, Bellmore, and Levittown has Fire Comm dispatch for them on 46.10 after hours, and then moves over to their department freq for ops.

Wantagh does not simulcast on 46.10. It may be Seaford you are hearing being dispatched by Wantagh.

East Meadow, Bellmore and Levittown are probably participating in the 911 direct dispatch program (not the official name, just made it up). Meaning, if a 911 call is received by Firecom, instead of them transferring the call to the respective department, they activate the department in order to speed up the response time. After the initial tones from Firecom, the respective department re-transmits the tones and takes over the job. Quite a few departments are doing this now in the area. It appears to speed up the whole process.

I know N. Merrick uses either 170.150 or 170.5125 for some ops. I've heard them transmit on one of these freq's before but I cant remember which one and what for.

I have noticed the increased time between the tones and the dispatch in madison county in central new york...it could be that they have moved to a computer toning system, instead of the traditional push button...just an idea.

Here is what I deciphered for the 9th Battalion. Again, feel free to post additions, corrections, etc.

900 - Bethpage - dispatches themselves on 453.9250R DPL 072/simulcast dispatch on 46.10. Ops on 453.9250R. Also heard faint simplex on 453.6375 DPL 411 which I have listed as their fireground.
910 - Carle Place - Disp by FireComm on 46.10.
920 - Farmingdale - Disp on 46.10/repeated on 46.120. Unknown if by Firecomm or 920.
930 - Hicksville - dispatches themselves on 453.2625. Dispatch simulcasted on 453.8375R, which is also used for Ops.
940 - Jericho - dispatches themselves on 460.6000R. Ops on same channel.
950 - Plainview - dispatches themselves on 477.1625R. Ops on same channel.
960 - Westbury - dispatches themselves on 453.5750R. Ops on same channel. I think i heard units refer to the base as 9600 instead of 960.
970 - South Farmingdale ??

 

[w2lie]

South Farmingdale dispatches on 46.10, and then moves up to 458.800 simplex for OPS
Hicksville was also dispatching on 0154.2050, simulcasting on 0453.8375

E911, looks good from what I have. 970 South Farmingdale is toned out by Firecom over 46.10 and then to 46.12 for truck to truck. They used to have a UHF ops channel but I thought I heard they werent using it anymore. Maybe someone could confirm. Go to Liquid Squelch's website as he has all of the ops channels for every nassau department. Its fairly updated as well.

I think Liquid Squelch has his information confused. 920 Farmingdale (not South Farmingdale unless this changed recently) tones out for themselves on 46.10 and switches to 46.12 and/or 458.800 for ops. The 458.800 is not repeated and only heard locally if around Farmingdale Village.

As for Westbury using the ID of 9600, it was set up this way to let the dispatcher know which channel he was being called on. If you remember, Westbury used to tone out on 46.12 with the 960 ID. When they got their highband channel, they were still using 46.12 early on until the changeover was complete. When a unit called 960, the dispatcher knew he was being called on 46.12. When they called 9600 which you hear now, it was to let the dispatcher know he was being called on the highband channel. I also think it had to do with the FCC. Maybe someone can clarify that. Several other departments use this same system, Levittown being one of them (6210 on their UHF freq and 620 on 46.32).

Thanks guys for the corrections and additions.

I do remeber them on 46.12 with the 960 ID now that you mention it. I thought they just switched to 9600 for who knows what reason...thanks for the education.

For LiquidSquelch...great website...I use your link to listen to Nassau. I lived on the south shore for 13 years and I still go back all the time to see family and friends. Maybe you should create a list like I've posted here on your site to keep everything for LI in one place. Just a hope/thought.

I have heard Farmingdale on 458.800 but never South Farmingdale...

And I live in East Farmingdale

And on a side not reception of E farmingdale 45.32 ops and Farmingdale 458.800 ops sucks with a scantenna 45 feet up...

 

[APX8000]

Yep...confirmed Farmingdale on 458.800 PL 114.8.

Hence why I said I thought Liquid had his information confused Probably a typo

I know Farmingdale is not repeated but you should be able to hear both sides from where you are. I was able to hear them from West babylon, both sides. I can hear them once in a while in Melville now, but its only 1 side. Check your coax b/c with a ducky antenna from where you are, I would guess you should be able to hear them.

Yah, It was a brain fart!

It might be useful to use some standard terminology when trying to sort out all of these different channels and FDs.

For example -

Paging Channel - this is the channel that the pagers listen to - some pagers might be on low band - some pagers might be on VHF or UHF

Response or Ops Channel - used by field units and dispatchers when responding to and returning from incidents

Fireground or Firescene Channel - channel used at the scene of an incident

(Some agencies might do all 3 of these functions on 1 channel - there are probably other channels out there also - chiefs channel - arson channel - hazmat channel - crossband channel - etc)

----------

Approaching from a different angle - the FCC uses this terminology.

FB2 - a repeater

MO3 - a repeater mounted on a vehicle

FX2 - a repeater that relays a signal from a fixed location to a fixed location (aka - a "relay" - a "satellite receiver link" - a "transmitter link" - etc)

MO - either a mobile radio (car or truck radio - usually from 20 to 100 watts) or a portable radio (typically 2 to 5 watts of power - I like to use the designation "HT" (Handi-Talkie) for portable radios

FB - a base station

----------

Some configurations for a fireground channel could be -

"154.22 HT" - portables (and ONLY portables) that operate on 154.22

"154.22 HT + mobiles" - portables and mobile radios that operate on 154.22

"154.22 HT + mob + FB" - portables, mobiles, and a base that talk on 154.22

"154.22 HT + mob + FB + FB2" - lets throw a repeater into the mix - (now there will be a input freq for the repeater to figure out)

"458.0125 HT + MO3" - maybe the Chief has a portable radio that transmits on 458.0125 to his car - and there is a repeater in his car that relays his message on to 154.22

"458.0125 HT + 453.0125 MO3" - maybe the repeater in the Cheifs car uses 2 different UHF freqs to relay the messages

"460.625 FB2" - maybe when the Chief talks on his fancy portable radio, his message gets relayed on a Chiefs Net (460.625R) and the fireground channel (154.22)

(I am just pulling the freqs out of thin air here)

As you can see, accurately describing all of the different aspects of these dispatch systems and radio systems can be quite complicated. And we haven't even talked about sorting out the PLs and DPLs.

Have fun - Peter S
