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 page 23).
Note that changing the audio source is not saved to memory. After reboot
the 518 kHz channel is always selected.
