Maybe dumb question, but I'm trying to program Dallas County Skywarn frequencies in my scanner and in the RR database there are Input and Output frequencies listed. Which do I program? Is Output if I were "Transmitting"? Any thoughts? Thanks.
Correct, for your mobile or HT, the TX Freq is the RX Freq of the repeater except for in talkaround/direct mode. For a scanner, you program the TX Freq of the repeater unless you are monitoring the input or direct/talkarounds.Input/output are referenced to the repeater. For a scanner you use output. For a real radio the receive frequency is output and transmit is input.
For the INPUT (RX) freq of the repeater there is an tone of 110.9 Hz CTCSS/PL. For the Output (TX) freq there is no tone AKA - CSQ.If you want to talk on the repeater you are going to need 110.9. For scanning tones not needed. Maybe your references are directed at scanning.
