Put in the frequencies that are listed under Site #2. They are the repeater outputs for that company. Example: 451.075 in output/456.075 is the input(mobile or ht). Also, note, that there are multiple listings of the same frequency. Don't put in any frequency more than once, it's not neccessary
Since it is UHF, more than likely it is an LTR system.
The Pro-96 will not track LTR systems. Still, program them in
conventionally and monitor it closely to see if you can detect a
pattern to how they are used.
