(34) SUB VFO-B RX & TX LEDs
These lamps select and indicate the current
status of SUB VFO-B. When the green RX lamp is
lit, the receiving frequency is under control of SUB
VFO-B. When the red TX lamp is lit, the transmit-
ting frequency is under control of SUB VFO-B.
During dual receive operation, the green RX
lamps above both tuning knobs are lit.
(35) SUB VFO-B Tuning Knob
This knob adjusts the SUB VFO-B operating
frequency. Tuning increments are the same as
described for the main tuning knob.
(36) LocK
This button toggles locking of SUB VFO-B tun-
ing to prevent accidental frequency changes. The
red indicator in the display glows when active (the
knob can still be turned, but it does nothing).
Press the button again to re-enable the tuning
knob.
(37) SUB SQL
This separate control sets the signal level
threshold at which SUB VFO-B receiver audio is
muted (and the green SUB Busy display indicator
turns off), in all modes. This control is normally
kept fully CCW, except when scanning and during
FM operation.

(38) CW and Electronic Keyer Controls
SPOT turns the CW receiver spotting heterodyne
oscillator on and off. BK-IN turns full break-in
(QSK) CW operation on and off. KEYER toggles
the internal CW keyer on/off, as indicated by the
LED above this button.The SPEED control is for
speed adjustment of the keyer/bug simulator.
(39) PITCH Control
Rotate this to select your desired CW tone
pitch (from 300~1050 Hz, in 50 Hz increments),
as shown in the display. The Tx sidetone, re-
ceiver IF passband, and display offset from the
BFO (carrier) frequency are all affected.
(40) CLAR Pushbuttons
Pressing the RX button activates the CLAR
knob, to allow offsetting the receiving frequency
temporarily (see item 41 below). The TX button
provides the same function for the transmit fre-
quency. If both buttons are pressed, the receiver
and transmitter are both offset from the original
frequency. Pressing the CLEAR button zeroes any
offset tuned by the CLAR knob. Each memory and
VFO retains all clarifier settings independently.
(41) CLAR
This knob tunes the clarifier offset frequency
up to 9.99 kHz when activated by the CLAR RX TX
buttons just below it (the 3-digit display appears in
the center of the display (if enabled) when the
clarifier is active).
