Spent Saturday at the Wrightwood Wildfire and Disaster Awareness Day event. The Angeles National Forest - Big Pines had a booth. We had Smokey walking around and we had one of the busiest Booths at the event. Firefighters from Engine and Patrol 38 were there as well as those of us in Recreation.
We got some tips from the guys on Engine 38. Although I've been through Radio Training in the use of the Bendix-King Radio in the Angeles National Forest, this is the first time I was told about using Tone 8 (Frazier Mountain) whenever we use "Direct" (F1 or F3). One firefighter told me it will work anywhere, even if you can't reach your normal repeaters, even if you're in a canyon with steep rock walls, it will always work. I always thought Direct was radio to radio like TAC 2 on simplex, but apparently that is not the case. A repeater IS required to use "Direct".
Sure enough I was listening to a Forest Unit that was dispatched to a fire off of Interstate 5 just south of Smokey Bear Road. He arrived on scene and was trying to give Dispatch a size up of the fire. He was very scratchy and unreadable. After Dispatch asked him to repeat his traffic several time, indicating that they too could not understand him, she told him to switch to Direct "Tone 8". Instantly the unit came in loud and clear even on my side of the Forest some 50 miles away.
I got thinking about how it could be that Tone 8 when using "Direct" would work so well. After researching it, I discovered that Frazier Mountain sits at over 8,000 ft and is in direct line-of-sight of nearly anywhere on the North side of the San Gabriels and the SCMRRD district of the Angeles National Forest. I suspect that that is the "magic" of using Tone 8 on Direct in our part of the forest, but I'm not sure.
For any of you that work the LAARD or SGRRD, what Tone are you supposed to use when on "Direct" Firenet or Admin? I doubt there is anyway you would use Tone 8.
Here are some pictures of the gang from Area 12 off the Angeles National Forest who work out of Big Pines.
