I was looking around for BC Forest Fire Frequencies and found this list on radioreference.com with no explanation of what's being used where.
Then I found the BC Provincial Natural Resource Sector Radio System page, which links to the Radio Communication Field Handbook, a 56-page pdf that includes pretty much everything about the system.
I was very surprised to learn that the Network comprises of:
The information on pages 40-41, and 45 is summarized here:
|Repeaters require a District Tone|
|No Tone for Simplex|
|Air - Ground Frequencies|
|122.050||1 Project Fires – Rotary||AM|
|122.400||2 Project Fires – Rotary||AM|
|122.850||3 Project Fires – Rotary||AM|
|122.900||4 Project Fires – Rotary||AM|
It's also probably worth mentioning that the Resource Road and Highway Channels are explained on pp. 18–21 of the Handbook but the frequencies are not listed there. BC Resource Road Radio Channel Maps can also be found on the government website.
