DHS / Customs / CBP

[Gilligan]

Is absolutely everything on 136.375 Customs? I'm hearing some stuff but I don't know if it's Customs.

Just tonight one of the Omaha units ID'ed 350.025 here in San Diego as 'BLUE 3'.

Federal Frequencies

Does anyone know frequencies for Brownsville,Tx or Rio Grande Valley.

Hi all,
Just saw this thread on a post to yahoo groups, wanted to add my 2 cents. Yesterday, 1/6/15, heard comms on 136.375 in Burlington VT, talk of homeplate. Did not get any callsigns. Also, have heard the 350.025 in use in Buffalo. That was about 6 months during my last trip out west.

136.375 is a common fixed- and rotary-wing CBP frequency.

Home Plate is Homestead AFB, in Florida I believe.

350.025 is/was also used as an air-to-air by CBP assets, though I hadn't heard of its use in several years.

350.025 is still used on a regular basis here in So Cal. A lot of the traffic is offshore and/or down south, so it's tough for me to to pull in most of the comms. But anyone with a clean shot to the Pacific from coastal San Diego should have it pretty good.

Here are some aircraft logged on 350.025 from my location over the past year or so.

Bear 26 calling Omaha 43.
Ocean 16 clg any Coast Guard vessel.
Omaha 3CS clg Hammer.
Omaha 61A doing intercept on a ULA. (This was out in Imperial County)
Zeal 01 and Zeal 02 clg Hammer.

136.375 is used a lot by the aircraft out of March and X-ray 9000 base. You can hear them discussing some pretty juicy stuff here at times.

Most of the Omaha aircraft here operate on MCS, TRANS, Wide Area 4 and the regular Border Patrol station freqs. Also log them on LA IMPACT from time to time.

am i going to hear any aircraft over sf bay area on these freq s

 

[KB7MIB]

Is that 136.375 freq FM mode or AM mode? Is there a set way to determine mode for 136-144?

108-137 is AM
137-138 is a satellite band. FM?
138-144 may be AM or FM (In Arizona, DEMA has FM repeaters around the state for their Disaster Radio Network. Luke AFB squadrons use AM air-to-air here.)
148-150.8 may be AM or FM

As I am seeing more use of 166.4625 DHS Common frequency here where I live in Tampa Bay. I haven't been able to find the NAC code for this frequency the agents are using digital mode and NFM for modulation and when I try to stop the frequency when the agents are talking it would be too late I won't hear them talking again for awhile. Does anyone know what NAC they use around Tampa Bay? I pick them up great where I live.

Northern Metro Detroit Intercepts

164.475 DMR DCC:1 CACH

163.675 NAC 351 TG 1 RID: 5112490, mostly AES encrypted, but heard "I'm in Michigan Delta Hotel Tango 50" and someone gave a description of a vehicle and an address. (Probable CBP)

163.675- NAC 110 , Enc

The CBP here in Brownsville Texas are using 136.375 Mhz and all is in the clear for air to air and air to base........

 

[ChrisP]

Be careful about assigning a NAC to the 166.4625 frequency. It's become more of a "federal common" than just DHS common, and all sorts of P-25 NACs have been used. I would probably leave it as P-25 search, just in case.

Just my $0.02 worth...

165.2375 DHS Primary NAC 301 (unk if CBP or other agency)
163.475 CBP
170.550 FBI (99% Enc)

Fairly active day and night.
Running subject names, criminal records checks, etc.

Sometimes they're encrypted. Sometimes they're sloppy.

Lots of mismatch if ya know what I mean.

I've heard they've been conducting a lot of air surveillance recently. Someone had a dongle and some software to decode an aircraft's mode C transponder data. He noticed planes circling areas for long periods of time and they always used the same squawk codes.

If they were training flights they would likely be squawking 1200 (VFR).

These planes were squawking something like 4415 which tells me they likely filed a flight plan. You can't just pick a random transponder code. Of course the planes were based out of a fake FBO.

Interesting.

165.2375 with the 301 NAC is CBP DNET-1 based on the NAC you got and the freq you logged. Did you get a NAC with the 170.550 freq? FBI is generally fully Enc.




$167= Generally FBI

Where is the damn Like Button +1

Altho Officially to be a certain NAC, those of us who regularly Monitor it, have seen multiple NAC's in use
