Change audio source
: The demodulated signal (1700 Hz +/-85 Hz) received on
518 kHz is always present for debug on connector J9. If a receiver is not performing
as expected, change the debug audio source to that receiver
(490 kHz/518 kHz/4209.5 kHz) and listen for e.g. a constant tone, indicating a
spurious on that receiver channel. The presence of a constant tone can then be
compared to the RF reception level measurements (see 4.4.3).
Note that changing the audio source is not saved to memory. After reboot the
518 kHz channel is always selected.
• To toggle the Alarm Relay click
