IMPERIAL COUNTY TALK GROUPS original list out of date

Come here to talk about the San Diego and Imperial County Regional Communications System. This is a great resource to share talkgroups and information about the countywide RCS.

Whew..... I feel as if I just finished writing a homework assignment! ;)

Two questions:

1) In ZONE 3, channel 5 is 39408 - El Centro PD. What is the "N" in ECN on that channel? (Full abbreviation is LEM ECN PD1) Could it be "E"l "C"e"N"tro? Continuing along that line, I would assume that "LEM" stands for "L"aw "E"nforce"M"ent?

2) I have not yet concentrated in the search for the Border Patrol chatter. Does anyone know the control frequenc(y or ies) for the El Centro Sector? Would appreciate any help given.

Scott,

I find that when the RCS folks program radios they tend to use the abbreviations used by the fire departments for the PD agencies as well. Each FD in the state is assigned a unique 3 letter ID by the state to help keep everybody sorted out. ECN is the ID assigned to El Centro Fire. ELC is the ID assigned to El Cajon. As you can see using "EC" for both agencies could be confusing when programming radios and consoles. I find that when they abbreviate talkgroup ID's when programming the radios, they tend to use whatever the FD uses for the PD as well, just to keep things straight. Just an observation, and not something I heard from the RCS people personally.

Sweet info!

Regarding Border Patrol you should search between 167-168 and 170-174 MHz for the most active channels. Here in SD, they use heavy encryption so your chance of catching any clear comms is not likely.

Here are some usually encrypted USBP/Fed freqs that I have picked up here in San Diego. These might be active in Imperial County too.

165.5625
165.9125
167.3500
167.3750
167.5125
167.5250 - Heard agents following a vehicle on I-8 West
167.6000
167.6500
167.7250
167.7625
167.8250
170.0625
170.3750
170.8375
170.8375
170.9125
171.5375
172.4000 - Very active
172.5125
173.4500 - Very active
173.9750

Unfortunately not too much info from me since I don't monitor these too much. I found these freqs when scanning through that range for a few evenings.

Thanks again for the Imperial County info.

Great question. Nether my wife or PD and FD friends know the answer to that. The majority of them are not scanner "nuts" such as ourselves and could care less what is programmed into their radios. They view them as a "tool" while on the job. 31 may know the answer tho.

Interesting fact - Calexico, Desert Shores, Salton Sea Beach and Salton City radios (base, portable and mobile) were programmed in San Diego! I have the feeling the majority of the rest of the radios owned by the county and other cities were too. Hendrix ( now Verison or something else) in the city of Imperial has for many years been the provider and installer for the radios. It seems when they get the new digital radios, they ship them to SD for programming. SD then ships them back when finished to the store.

My wife picked up a new bunch of digital Motorola's from "Hendrix" (damn, I wish I knew what their new name is! I'll have to ask her) six months ago to give to her brother. He is the chief of the VFD (volunteer fire department) in Salton Sea Beach. I'm kicking myself for not looking at the "from" address on the box that came from SD!

When BP switched to using their encryption, they also changed all of the frequencies, however they remain in the same band.

I have a list of the new frequencies. If anyone wants them, send me a private message or email. I used to monitor them, 90% encryption, some in the clear. Very and boring to listen to.

"and ALSO a call for a ladder truck from Mexicali."

My wife told me the federal government and Mexico have an agreement for the use of mutual aid in fire emergencies. (At least in our county. Does not know about others.) It works like this:

Whomever is in command at a fire scene after determining that the "equipment" that arrives from surrounding agencies/cities by way of a county mutual aid call is not wholly sufficient, will then order the fire dispatch to request additional aid from Mexicali.

Fire dispatch will then contact ICSO Central dispatch by land-line and relay the info. ICSO will then land-line Calexico dispatch and repeat the info. A Calexico dispatcher will then land-line Mexicali's fire dispatch center asking for the mutual aid. She will also land-line Customs at the Port of Entry making them aware of the situation so as to allow a smooth cross-over for the Mexicali FD into US territory.

Calexico has been designated this task due to their obviously being situated right at the border and all their dispatchers are bilingual. (The county may pay them extra bucks too?!) Calexico, by the way, also takes many calls and makes arrests at the Port of Entry. Mostly with DUI's, warrents and such. Never with people or drug smuggling tho. The feds handle that themselves.

It's a strange ageement with Mexico, the feds, state, and county.... yet it works darn near perfect.

Thanks for the info, that really intresting. Here in San Diego, we don't deal with mexico at all on a basis like that. At the pd we have a liason unit, but that doesn't really have any effect on day to day ops. When there are fires on the other side of the border we just tell the caller thanks, and do nothing. The only coctact I have had with any mexican public safety is when the Ambulance crews do transfers at the border. They call 911 from the payphone. They speak zero english, and just call for SDFD when they get there. I read a while back about a IB lifeguard saving a mexican lifeguard, I wonder how they found out about it.
