Sets the top of the AM band for seek.
Selects frequency spacing for AM seek. Default is 10 kHz
spacing.
Sets the SNR threshold for a valid AM Seek/Tune. If the value is
zero, then SNR threshold is not considered when doing a seek.
Default value is 5 dB.
Sets the RSSI threshold for a valid AM Seek/Tune. If the value
is zero, then RSSI threshold is not considered when doing a
seek. Default value is 25 dBuV.
Sets the output volume.
Mutes the audio output. L and R audio outputs may be muted
independently in FM mode.
