I have been listening to all the Mingo BOE and Bus frequencies. I have not heard anything on those frequencies for a very long time. Everything is working on my scanner and my antenna is outside with only 30 foot coax. My question is there any other system they may be using now. I have searched on the scanner trying to pick up anything new but, with no luck . I have not found anything new on the net that would help. Thank you everyone for any help . God bless.
