Better Air to Ground Frequency Information
I just completed the list of air to ground frequencies assigned by the National Interagency Fire Center. There are a few changes for 2014. My list is on the Wiki page for the NIFC incident radio system. Go to the database and click on "Nationwide Frequencies" then scroll down to the "Natl Incident Radio Support Cache / Natl Interagency Fire Ctr" link. When you bring that page up click on the Wiki tab. The information I've written there came from very good sources. The only info I could not get is the 2014 version for the Southern Area Geographical Coordination Center. I had to leave the 2013 information in the table.
There were some changes in frequencies for a few channels and some reassignment of channels for quite a few zones. My sources are pretty good. I don't have any way to present the zone info because I don't have any maps I can put on the site.
I haven't had time to make a database submission for this.
