No, it isn't rebanding. Control channels changing depends on the system. On the Broward County system, it used to rotate every day. Then it stayed on one frequency for many months. Then it changed to a different frequency, and it's been there ever since. I have witnessed on rare occasions it changing several times in a period of a few minutes. If you program them all, this won't matter.pinellasfirefighter said:yeah i have them all programmed in.. the whole system went down when it changed over there was no control period for about 5mins.. thats why i thought maybe the rebanding took place.. the control hasnt changed in over 5 yrs or more..
