Using DVAP/G4KLX image on Pi2 and have tried to change physical frequency of DVAP from 431150000Hz to 431125000Hz without success. I use D-Star Config and select 'modem' tab and 'DVAP' and enter the new freq which appears to be accepted, press 'Save' and exit. However upon reboot the DVAP frequency remains the same. Can't remember if I did something else when I first configured system a few years ago. Is there another entry somewhere else that I should be making?
Since nobody else has, will answer my own question since it may be of use at some stage. To change DVAP frequency, D-STAR repeater must NOT be running. I was running D-STAR Config, saving it with new freq and then stopping and re-starting D-Star Repeater. When you save the new freq it says D-Star repeater should be (re) started, implying that it's ok to have it still running while you make the edit. No.
