Hi Marcy how are you, so if I could ask what p25 digital conventional frequency or trunked p25 system do you find that 043 is giving you access to? It is a legitimate NAC, could be a government agency.

I looked it up in Wiki and it could be ICE who have used that NAC but that's in no way necessarily the case.

I've been doing some sniffing around on the internet and I'm not seeing any federal agency in the North Shore Suffolk County area but of course we could be talking about Connecticut all the way to Manhattan.

I will say this though, I have been getting excellent tropospheric ducting on the VHF high band, especially the Marine Band, on channel 16 just south of Trenton, New Jersey where I live on the Delaware River I have been getting Coast Guard sectors that I would never normally hear so..

Some pretty smart people up on Long Island and as more people see your thread you might get the answer you're looking for🙂

Yes on the NAC
No with the NAC and the Freq Posted

ENC??? CLR ???
RID Format ??

Seems to be a lot of NY/NJ area changes being found, in recent weeks.

Outside of the Political On-going Crap, the only known event coming up is UNGA - wondering if all these apply to that
or there are whole-sale changes on-going to other networks. Time shall tell - NICE Find

It would be helpful to post frequency in the subject line in addition to the nac code you are referencing.

The minute I saw that Marcy I thought of Robert De Niro in the movie Taxi.. LOL

I am still getting tropospheric ducting on VHF High, are you still monitoring 170.5625? Doesn't seem like you're getting many replies.

any info on RID's for this new $043, might help point toward atleast the agencies who use a standard RID format

Sorry to bring up an old post.

When this thread was started, I was receiving TSA PHL (Philadelphia International Airport) with a NAC of 052.

I'm now receiving TSA PHL as follows:
406.7375 MHz NAC 043 RIDs 8109XX, 1006XXX, 1009XXX with a mix of P25C & P25E

Not sure if this helps any.

Also, The Fed Files Blog (not sure of the date), shows TSA PHL as using NAC 043 on two other 414.6125 & 415.7375 MHz.

Wasn't the $052 from their old VHF, or did you get this also on UHF - 99% of the airports when they moved to UHF also changed NAC's

Mystery now solved - with Team work and band openings :)
415 would be the input to 406.7375 (+9)

Now to nail down $10E in the PA/NJ/NY area as well

Sorry, yes NAC 052 was from the old 172.900 MHz RIDs 768XXX & 769XXX from 8/2023 mixed P25C & P25E

No 10E though, VHF or UHF. What frequencies?

Another thing that I just noticed is that I have 10C & 10D for TSA, but no 10E on my NAC spreadsheet.

for your 10C/10D are those VHF or UHF - when they went to UHF the assignments totally changed and there is/was no correlation from the VHF to the UHF

ie: Boston went from being assigned 041/042/043 - where 041 (VHF) was the Primary to only being heard on 01C (UHF) now

I have no 10C or 10D in my SEPA recordings. My NAC spreadsheet has 2 columns; NAC & (possible or recorded) entity.

I'm pretty sure that I took the info from the RR Federal NAC Codes Wiki and pasted it into an Excel spreadsheet.

I only had 10C in VHF for GSP in SC and 10F in VHF for Mobile AL
