VFO Operation
If you press the keypad band key for the same
band that you are already operating on, the dis-
play will shift to a different frequency in the same
band (the bottom of the band by default). Pressing
the same band key again switches you back to the
frequency you were on before. What you have
here are two completely independent VFO selec-
tions for each band, selectable by each band's
keypad key. You can think of the VFO for every
band having a "frontq9 and "rear" half that can be
swapped for operation by toggling the band key.
You can tune, select a mode and a bandwidth for
each of these two VFO halves in each band, and
they will be remembered until you return to this
"wb receiver9' selection.

Toggling VFOs
\
A practical use of this feature is to configure the
front VFO for phone operation, and the rear half
for CW operation on the same band (see the
illustration above).
For example, if one of your VFOs is set to the
SSB portion of the band (and in an SSB mode),
press the keypad key for that same band, tune to
the low end of the band, and press the
CW
mode
button. You can consider this your CW VFO. Now
press the band key again several times, and no-
tice that operation toggles between the SSB and
CW VFO halves. You can also select different IF
bandwidths as well as modes for the two halves
(and even different clarifier settings). Note that
this feature is not related to the MAIN VFO A and
SUB VFO B scheme - dual receive and split
operation will be covered later.
VFO Selection & Receiver Muting
Above the Main and Sub VFO knobs are a pair
of button1LEDs labeled
RX
&
TX.
The illuminated
green
RX
LED indicates the selected VFO re-
ceiver, while the red
ax
LED show the VFO con-
trolling the transmit frequency. As we will see later
on in dual and split operation, these buttons con-
figure semi-duplex operation as you choose.
You can mute the Main or Sub VFO at any time
by pressing the
ax
button/LED above the corre-
sponding VFO knob. The LED blinks while the
receiver remains muted; simply press the button
again to unmute.
Keypad Frequency Entry
Frequencies can be entered directly, if desired,
as follows:
Press at the lower right corner of the key-
pad (the leftmost operating frequency digit will
blink). Then, referring to the yellow numbers on
the keypad, enter the digits of the new frequency,
from left to right (1-4-2-5-0-0-0), followed by
rn
again. As you enter the numbers, the next digit to
be entered will blink on the display. You can use
the
DOWN
and
UP
buttons below the keypad to
reposition the blinking digit location as desired
(but ignore the direction labels on these buttons).
Only when you press the second time will
the operating frequency actually change, so if you
decide to remain on the original frequency after
starting to key in a new one, you can cancel any
entered digits by pressing
Eil
(""Clear Entry", the
yellow label at the lower left corner of the keypad)
instead of
PI.
Note that, to enter frequencies
below 10 MHq you must key in the leading zeros.
That's all there is to tuning Main VFO-A. Sub
VFO-B has a lot more features of its own, which
we'll look at in detail later. First, however, let's look
at some other important receiver features.
