While listening the other day to the Fire Academy Repeater (453.71250 R 162.2), I heard them say to go to channel 3. I thought it may have been the other licensed channel of 453.81250 R 162.2, but no such luck. Anyone have a clue as to what it could be? Possibly the same channels (including the i/p) in talk-around mode as my first guess?? Looks like I have a new can of worms to solve here... Any intel is greatly welcomed.
