Having lived here a short time, I don't pretend to understand, yet, how all of this works. I'm under the impression that R-M dispatches for many of the Yavapai County rural FD's, using numerous remote repeaters. That being said, I've been listening to MFD for the past year on numerous frequencies, but mostly 150.805 and 154.13.
Today, while listening to MFD on at least three different frequencies, I realized that I haven't heard anything on 150.805 for at least the past couple of weeks, if not longer. Is this frequency down, or not being used for some reason?
