w RF GAIN CONTROL/SQUELCH CONTROL
[RF/SQL] (outer control; p. 35)
Adjusts the RF gain and squelch threshold level.
The squelch, when closed, mutes the speaker or
headphones when no signal is received, reducing
noise.
• The squelch is particularly effective for FM mode. It is
also available in other modes.
• 12 to 1 o'clock position is recommended for any setting
of the [RF/SQL] control.
• The control can be set to 'Auto' (RF gain control in SSB,
CW and RTTY; squelch control in AM, FM and WFM) or
squelch control (RF gain is fixed at maximum) in the mis-
cellaneous (others) set mode as follows. (p. 129)
