Here are three I have on file. The websites shown on the video portions of the recordings are good ones. One is something like "bigbearscanner.com" and the other "socalmountains.com." There are additional recordings on those sites. A real good source that you may have heard of is "wildlandfire.com." Somewhere on that site is a list of recordings that might be better than those I've given you here. Good luck!
EDIT I can't get my saved recordings from bigbearscanner.com and socalmountains.com to load. Going directly to the sites, if they are still active, to find those. I think wildlandfire.com has some pretty decent ones. On the bigbearscanner site the Emerald Fire recording has some good listening as CDF and the San Bernardino NF go through a process to establish unified command on an initial attack of a fire moving rapidly through three different jurisdictions.
