Federal Freq Identification Thread (Consolidated)

[riveter]

I've already made an eastern shore related federal thread and another one for a specific frequency, so I think it's about time I started just dumping everything in one place rather than all over (kinda like the milair guys do).

My UNID/partially ID'd list from the last 7 days. Some may be repeats, in which case I apologize.
-------------------------------------------------------------------------------------------------------------------

163.625
NAC 093

Hi, Just want to let you know that I receive 164.1750 from my location (see screenshot), NAC, TG's and RID's in 2nd screenshot.

 

[gesucks]

Is a mistake on DSD+ or are they really using KEYID 1? ->encryption coordination FAIL!

 

[riveter]

Hey cool, that's a dang long way away to be getting that.

I've submitted the CIA SFTRS to the database, however they want to put it in.

-------------------------------------------------------------------------------------------------------------------
165.65 - No US DB history. See below.

Ah crap, you're right, and I didn't realize it. Gonna take more monitoring then. Those were the frequencies on which those transmissions were centered, with my SDR properly calibrated for correction and compensating for dynamic heat drift. So, either I'm getting an image, something else is hinky in my setup, or their repeater's RO is horribly off-true (obviously not likely)

I'll fix those when I hear them again. Thank you.

419.900 DPL 023 I believe is Coast Guard Curtis Bay Security. A few years ago when I was in the area, it hit on close call, I forgot about it, but recently found it again in my scanner and started listening to it and it sounds like security.

Might be worth trying, I believe 163.72500 NAC 085 and 171.32500 NAC 086 are connected. Have the same traffic.

FBI Baltimore using a Baltimore area FIO net - LE 3.

Had just typed that in and was about to program it in my scanner to get some OTA confirmation... saved me the trouble

DB update (s) incoming with a few things. I'll post relevant updates to this list once I get that done.

LeSueurC, I think I know what system that all is part of, I've been adding the bits together for a while. Would you be kind enough (if able) to let me know what RID ranges are showing up there, and the approximate geo area of strongest signal strength when you've been monitoring? I think with that, I'll know for sure.

848xxxx, some 846xxxx. Down here in VA the Signal seems to be strong around Norfolk, I'm sure for the same 2 frequencies it would be strong around Baltimore.

 

[riveter]

Thank you! That tallies with what I've seen on the system I think it is part of, in which case it will not be strong around here. Those freqs are, I believe, part of DHS Washington Net, which is a large multi-site conventional system that has a brother up here in Baltimore. I just submitted one piece of the Washington system and a bunch of bits of the Baltimore system to the DB.

OTA, it appears that each geographical area has one repeater networked to all the other repeaters in that system. The systems do not appear to be linked by simultaneous transmission across sites in the two systems (if I hear something on the DC system I won't hear it multicast on a Baltimore repeater), and the frequencies do not appear to be set up for any simulcasting - it appears to be very multicast-oriented.

TL;DR, I haven't heard diddly on those frequencies up here so far, I think because they're only part of the DC system and only physically active on repeaters down by you.

Thanks for the ID on the USCG Yard at Curtis Bay.
Also strong in the north end if Anne Arundel County along with this 419.900 are the following. Anybody have ID on them?

409.4375 DCS 065
410.4875 CTCSS 218.1
407.8625 NAC F0 (P25)

All sort of sound like security outfits of some sort and are fairly active (all while I wrote this entry) but I have not heard any of them say anything to ID who they are.

Users maintain strict, very military comms discipline - more so than MP units. Users likely DSS or other high grade sworn security (if there are any other such units in DOS).

My thinking is a wide area multicast DOS system for security (definitely building security chatter OTA)- there's way too much activity on there to be anything just in the Baltimore area. I love the comms discipline though, these guys impress.

410.4875 [419.4875] is a nationwide FEMA frequency pair, and I heard a little bit of traffic (unidentifiable) with the same PL the other day. Not sure what's up there, but I've got an ear out.

One more with less activity and also a security flavor to the comms is 407.600
