on another note, when i left work, we were still on back up radios... and about 715, radio shop started going through all of the channels, asking dispatchers how their signals were. and it sounds pretty good right now..
as for "back up" - as someone else previously stated, just back up repeaters, that do not put out near the power of the full system. - as for the backup systems back up, we have our repeaters.. analog, non trunked that we can utilize if needed. (which are known as west repeater (goddard), north repeater (park city), south (haysville), and east (not sure where its located), and there is one other repeater, that i believe is near down town. (not the court house repeater)
to know what the freq's are, is a different problem, because i have no idea..
