This is just part of the rebanding of site 8 folks!
I was messaging with KX5MOT and he inadvertently answered a question that I had about the frequencies still in use that are above 854 MHz which are not for public safety use after rebanding.
All of the frequencies currently in use on site 8 are not rebanded frequencies. Eventually, none of the frequencies on site 8 will be above 854 MHz. That means the current control channel 857.9375 is going to disappear one day and a frequency below 854 MHz is going to take its place. At some point, which for me is probably tomorrow, the new frequencies need to be programmed into scanners so they can find the new control channel when the change is made.
