102, on the other hand, might just be the Atlantic City site.

I know this isn't a ton of help, but I tried to get my linux server in LBI (Brant Beach) to lock on to 102 via OP25 as I am not down there currently and this is what I got

received unknown nac 0x4f2, mtype 3 len configs 0 msgq_id 0
received unknown nac 0x4f2, mtype 3 len configs 0 msgq_id 0

received unknown nac 0x4f2, mtype 3 len configs 0 msgq_id 0
received unknown nac 0x4f2, mtype 3 len configs 0 msgq_id 0

As expected, I could lock on to 115.

I experienced the same results on Trunk-Recorder. Could not lock to 102, but could to 115.

I am using Google Maps. Type each name and it will draw a border around the limits. Border to border is 10 miles.

Long Beach Island NJ wont display a border for me. Long Beach NJ does draw a border and that border includes Tuckers Island. Tucker to AC is 10 miles. But Ac to where it actually says Long Beach Island comes up 23 miles. Where are you on that Island? What's a close landmark?

Some tropo tonight. Usually get site 102 with 171.6125. Tonight that freq is giving me site 129.

115 is not Atlantic City...it's much closer to LBI. 102, on the other hand, might just be the Atlantic City site. I guess someone will have to drive around to confirm.

My brother went for another one of his infamous drives today. He found Site 115 in Manahawkin. He's 95% confident it's the 370 Hay Road tower, but it's definitely in Manahawkin and within 0.5mi +/- of Hay Road. I'll be submitting.

 

[RadioDitch]

Just to add, Sean stated that 102 is definitely somewhere south of Manahawkin.

Haywood Road,tower is home to the local FM station 105.7.

102 is Atlantic City. Good sleuthing. I'll get them both added tomorrow morning.

 

[RadioDitch]

Haywood Road,tower is home to the local FM station 105.7.

He tracked it to that area, and there are VHF antennas up on the tower. Regardless, definitely in Manahawkin.

 

[elias1988]

Explains the 99% decode rate then since I’m not far from it,looks like there was some work being done on the tower the other day with a crane.

In Wildwood, NJ using DSD+ w/ a telescoping antenna inside I received sites 102, 115, 130, and 143. Site 143 was strong, medium signal from 102 and 130, and a weak signal from 115.

 

[GTR8000]

In Wildwood, NJ...Site 143 was strong

I suspect you're on to something there...

That makes sense, I just realized that I brought the wrong antenna with me (800), so being in Manahawkin makes much more sense. This seems like a lot of infrastructure for just 1 agency.

It's not just one agency. The USMS "owns" the system, but there are numerous federal agencies using it throughout the region.

 

[RadioDitch]

Sean is working way down south again today and confirms this morning that 102 is definitely in Atlantic City.

On Site 143 he has between a -40 and -28 RSSI in Cape May. So his conclustion is 143 is definitely in Cape May somewhere. The strongest signal was in the area of the NJICS tower.

Like GTR said, it's a wide range of alphabet soup using it apparently. Also, as previously mentioned several times in this thread and elsewhere, there seems to be a trend of systems like this popping up for various DOJ/DHS/Federal collectives around the country. Seems like a shift in ops is happening away from conventional in a lot of metropolitan areas.

Lil brother sure gets around! Nice job. Here is the updated unknown list w peers @GTR8000 style.

My guess is 143 will be Cape May/Wildwood and 130 Millville/Vineland.

Site ID	Control Channel	Peers
129 (CT?)	171.6125	117 (Trumbull), 122 (Islip), 127 (Plainview)
130 (SNJ?)	170.3375	102 (ACY), 115 (Manahawkin) 128 (Philly), 143 ( ? South Jersey)
143 (SNJ?)	168.8875	102 (ACY), 115 (Manahawkin), 130 ( ? South Jersey)

 

[RadioDitch]

Lil brother sure gets around!

Part of how he makes a living.

As to 130, opinion is it's probably gonna be further northwest of Cape May than the Millville area. He said the other day it was stronger around Winslow than when get got south of there.

As to 129, it's coming from basically due East of his house in Garwood. So he and I both think it's another NYC/LI site.

 

[RadioDitch]

Decided to shake some rust and join in the fun while I'm down in Jersey visiting family. Site 144 at Morristown Airport is gone. No longer on the air, all static, no longer listed as a peer of Randolph. Verified with Unitrunker 2.1.0.97 and the requisite SDR. It's odd. Perhaps it was a temporary site not unlike the NJICS STR Trailers and it has been moved?

Either way. It can be removed from the database. (Submitted)

No changes to Randolph.

Site 122 was isolated this am but now its not.

Why do they switch back and forth? from 406.812 to 406.612 I noticed
as soon as 612 stops it jumps to 812 and so on? 73,s Marcy
