serve a frequency shift on the display. This shift repre-
sents 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 changing. If you do
not want this frequency shift to appear when changing
modes from (for example) USB to CW, use the Menu
item "062 A1A FRQ DISP", described on page 122.
ceiver, rotate the ( VFO-B )[ SQL ] knob clockwise just
to the point where the background noise is just silenced.
This is the point of maximum sensitivity to weak sig-
nals. Excessive advancement of the ( VFO-B )[ SQL ]
knob will degrade the ability of the receiver to detect
weak signals. Adjustment of the VFO-A squelch is ac-
complished using the ( VFO-A )[ SQL ] knob.
