In light of National Guard troops being deployed at the US Mexico border, does anyone have insight into the freqs, talkgroups and radio systems the NG's will be using to patrol the border region? Encrypted or in the clear?

They are most likely encrypted and im not sure of the frequencies though.

They will have BP radios and BP is total ENCRIPTED on the system.

I would expect that if they're using 'tactical' radio at all, it'd be their own military version, the regular military field tactial SINCGARS system, in the 30-54 MHz range (They cover wider, but aren't likely to be used there inside the US.)

They can use single channel mode, but standard is to use frequency hopping/encryption, when it counts.

Possible they'll be using the Military version of FRS, or actual FRS radios, too, though. You never know what supply will provide.

During a HIGH SPEED (120MPH) pursuit by El Cajon CHP last night (after 7pm going east on I-eight), I believe that the pursuing unit said that he talked to BP on their radio to request a spike strip. (They did not make it and the vehicle went all the way to Arizona, I think!) Can field units use LAWCC or is there another M/A TG for such communications with BP and others? Or is it possible that the El Cajon CHP units have 3 radios, RCS, Low Band, and BP?

Hmm. There's a Border Patrol Call group on the CITY trunk, but I don't see one on the County trunk. Of course, they may simply sit on the all agency mutual aid channels, there. Or, they may simply have a 'BP Call' talkgroup that hasn't been discovered yet. FBI certainly has a bunch of assignments on the county trunk, now.

Now that you remind me, I recently saw something in writing that said that those TGs were Federal Mutual Aid, not specific to FBI. I just don't remember where I saw the info.

I picked up the Border Patrol in the past on Law CC (33600) and Imperial LAW CC (41920) when they need outside agency assistance.

163.5625 206.5 I believe might be used by the National Guard.

Also perhaps the BP have some common freqs in their radio such as CLEMARS? Maybe they used that or some other simplex freq.

I believe that the correct way for unit’s from one agency to hail
another agency is to go to the law command TG for that loop (south, north, etc.)
announce them selves (SDSO 70-Paul Sam -1 to the agency they are hailing)
and go from there. And if this is not exactly how it’s done go to the L.E.A.N.
web site you can find San Diego law enforcement radio protocol.

In the east county areas, SDSO, CHP, BP, BLM, and State Parks units mobile in the field use RCS Rural Tac 80 for comms between units.
