I have always wondered why Baltimore County has maintained the low band system. One of a very few still operating on in Maryland. Was VHF 150 band ever discussed in years past. I understand now that all career stations are dispatched via digital signal no longer requiring the low band. Im guessing as soon as the low band breaks for good the system would be dropped all together. Does anyone have any insight from years past about the 46.460 frequency and why the county never switched to vhf or Uhf ?
