Cleveland National Forest frequencies

[paulmcg1]

I live up in the Cleveland National Forest, in El Cariso Village. Here are the US Forest Service channels I have in my scanner. They use CTCSS tones to reduce interference and control the repeaters. The CTCSS tones are usually the ones listed below, but they change them occasionally as needed. Radio Reference has the full tone list and other information at http://www.radioreference.com/apps/db/?aid=4301

* 168.15 MHz "Admin Net", CTCSS 103.5 Hz (tone 8) -- mostly used by the rangers. For example, I've heard them running the plates of vehicles they have stopped.

* 168.75 MHz "Forest Net", CTCSS 103.5 Hz (tone 8) -- used by the firefighters for fires as well as accidents on Ortega Highway.

* 171.425 MHz "Forest Net" CTCSS 127.3 Hz (tone 12) -- I think this is a new frequency for a local repeater, it came in very strong during a recent frequency sweep.

Hi,

Thanks for the updated freq. I show 171.425 as the input to 168.750.

One additional freq: 171.7875 $40B (P25 digital) CNF Law Net. It's pretty active from units in the Ortegas. Input is on 162.9625.

172.275 103.5 PL is the rumoured new frequency for Forest Net whenever they do the switch over.

I bet you have some great reception up there. Must be a scanner listeners dream

The switch is on hold. They apparently figured out that the proposed input was the IFB for a local AM radio station.

I found a couple of mutual aid agreements between Cleveland National Forest, Corona FD, and Orange County Fire Authority.

In a mutual aid situation, CNF could disable CTCSS tones. In addition to "Forest Net" (168.75 MHz repeater output) and "Admin Net" (168.15 MHz repeater output), neighboring fire departments are supposed to use these frequencies (without CTCSS).

* 168.2 MHz -- NIFC TAC 2 (primary tactical)
* 168.05 MHz -- NIFC TAC 1 (secondary tactical)
* 170.0 MHz -- US Forest service aircraft (this is kind of odd, I read that "170" was going to be taken away by the NTIA)

The Forest Service is also authorized to use local frequencies during a mutual aid situation.

+ Corona FD dispatch 154.235 MHz repeater output (input on 159.165 MHz). Both sides use 103.5 Hz as the CTCSS tone.
+ Corona FD TAC 1 154.04 MHz, no CTCSS
+ Corona FD TAC 2 158.745 MHz, no CTCSS
+ Orange County trunked 800 MHz system command channels 5C, 4C, 5B, 4B -- see http://www.radioreference.com/apps/db/?sid=201
+ Orange County trunked 800 MHz system tactical channels 5E, 4E, 5F, 4F, 5N, 4N
+ Orange County trunked 800 MHz system aircraft channel 5A
+ Orange County trunked 800 MHz system hand crew channel 1B
