if you do not have Rig control, as if using a standard 2-meter mobile rig, I have found that, you need to alter the VarAC_frequencies.conf file and list the frequencies that you plan to use in Hz (not the standard MHz), if you want to show up on the PSK Reporter map as 2 Meter freq. 145090000, and 145650000 are examples (no decimal points). Tested!
