The 2009 FIRESCOPE Radio Communications Guidelines (MACS 441-1) is now available on the Internet at:

The most interesting change for this year is the designation of National Interagency Fire Center Commands 8 - 12. The frequencies are already known, if you have been following the development of the Department of Homeland Security "National Interoperability Field Operations Guide." Commands 8 -12 are the same as the VHF Incident Response NC 1 and IR 2-4 channels.
I have heard that NIFC Commands 13 - 18 are assigned by incident using "excess" or unused federal frequencies in a relatively small area of the nation. California has 4 of these areas. So as the fire season begins to wind up we all need to listen to those large incidents and report the frequencies in use.
I'm thankful that I now have a couple of PSR-600's and their large memory capacity to easily add these new frequencies to all my files.
