modes. 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. 131)
• When functioning as RF gain/squelch control
• When functioning as RF gain control
(Squelch is fixed open; SSB, CW, RTTY only)
• When functioning as squelch control
(RF gain is fixed at maximum.)
