I am trying to map two LTR systems in Tucson, both are Action Communications and I am using my PRO-97, for system one I have found frequency 461.1500 to be R21 or home repeater channel 21 on system two I have found 463.3250 to R30. If anyone has any more info they can share I would appreciate it, on every burst it does not show home repeater information its like every 10 to 15 that is shows something.
