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