Analog audio receiver

HAVOC adds a few features to the original Analog audio receiver.

Centering cursor

In any mode, set the focus to the waterfall display by pressing down multiple times, a red dot will blink in the center of the frequency scale. Use the jog dial to move it and press the center button to center the receiver to that new frequency.

Squelch setting

Only in NFM mode (SQ xx/99). Higher means less sensitive.

Audio spectrum

Only in WFM mode. The range is 0Hz - 48kHz from left to right. The 19kHz stereo pilot tone can be seen when the receiver is centered on a commercial radio station.
