If you press the (VFO-A) [BAND] button, the
[SUB VFO-B] knob may be used as a band selec-
tion knob. If you press the (VFO-A) [MHz] but-
ton, rotation of the [SUB VFO-B] knob allows fre-
quency navigation in 1 MHz steps. Depending on
the setting of the (VFO-A) [BAND], (VFO-A)
[MHz], and [A/B] buttons, the function of the [SUB
VFO-B] knob will change.

When changing modes from SSB
to CW, you will observe a fre-
quency shift on the display. This shift represents
the BFO offset between the “zero beat” frequency
and the audible CW pitch (tone) you can hear (the
pitch is programmed by the [PITCH] knob), even
though the actual tone that you hear is not chang-
ing. If you do not want this frequency shift to ap-
pear when changing modes from (for example) USB
to CW, use the Menu item “061 A1A FRQDISP,”
described on page 118.

This is the point of maximum
sensitivity to weak signals. Excessive
advancement of the [SQL] knob will
degrade the ability of the receiver to
detect weak signals. Adjustment of the

is connected, you may also press the
[ANTENNA RX] antenna selection
button. Two TX/RX antennas may be
connected, or one RX-only antenna.
