"1. "A" VEO is for both transmitting and receiving and is
selected by placing the VFO
Select switch in the "A"
position.
The transmit and receive frequency will be
controlled
by "A''
VFO, displayed
on the LED
fre-
quency readout, and stored in "A" memory.
2. ""B' VEO
is for both transmitting and receiving and is
selected
by placing the VFO
Select switch in the "B"'
position.
The transmit and receive frequency will be
controlled
by
"'B'' VFO,
displayed
on the
LED
fre-
quency readout, and stored in '"B'' memory.
3. RA-TB:
The
receive frequency
is controlled
by "A"
VFO
and the transmit frequency is controlled
by "B"'
VFO.
Both frequencies
are stored in their respective
memories,
and
displayed
during their respective ope-
ration times
(""A'" frequency
during
receive, and "B"'
frequency during transmit).
4. RB-TA:
The
receive frequency
is controlled by "'B"
VFO
and the transmit frequency is controlled by "A"
VFO, the reverse of the above.
Again, both frequencies
are stored
in their respective memories, and displayed
during their respective operation times (this time "B"'
frequency
during
receive
and
'A'
frequency
during
transmit).
When the !IC-701 is first turned ON, the frequency displayed
on the LED
readout is the lowest frequency
limit of the
band selected by the band switch.
FOR
EXAMPLE:
lf the band switch is set to the 7MHz band, when the set
is turned ON, 7.000.0 will be displayed on the LED readout.
This will occur whether the VFO switch is in either the "A"'
or "B' or combination VFO position.
Rotating the tuning
knob clockwise will increase the frequency in 100Hz steps.
Rotating the tuning knob counter-clockwise will decrease
the frequency
in 100Hz steps.
Note:
Rotating the knob
counter-clockwise
immediately
after applying
power
will
not lower the frequency as it is already at the lowest limit.
Switching from one VEO to the other VFO does not clear
the first VFO.
The frequency
is retained in the VFO's
memory.
EXAMPLE
lf 14.125.0MHz is set with ""A'' VFO, and the VFO switch
is set to ""B'' VFO, the frequency LED readout will show
"B'' VEQO's frequency, but 14.125.0MHz
is still stored in
"A" VEQ's memory.
Returning the VFO
switch to "A"
VFO
position,
and
14.125.0
will
be displayed
on
the
readout.
Accordingly, if the switch is placed in the "'B"
VFO
position,
the frequency
that was set with the "'B"'
VFO will appear. This allows you to set a certain frequency
with one VFO, work up and down the band with the other
VFO, and periodically check the set frequency simply by
switching between "A" and "B" VFO.
It also allows you
to search for aclear frequency with one VFO, while keeping
your operating frequency on the other VFO.
When you
have found a clear frequency, switch back to your operating
frequency, inform the station you are in contact with of
the new frequency, and switch back.
It's that simple!
The
1C-701 will perform this operation even on two dif-
ferent bands.
A frequency is set in either "A" or "B'' VFO
on one band, the VFO switch is set to the other VFO, and
the band switch set to any other band you wish to work.
When you want to go back to the set frequency, first return
to the original
band
and
then
to the
original
VFO
and
you're back on the set frequency.
FOR EXAMPLE
Set "A"
VFO to 14.255.0MHz.
Set the VFO switch to
"B'' VFO.
Switch to the 21MHz
band.
The frequency
readout
will read 21.000.0MHz.
Operate anywhere you
wish
with
"B'
VFO.
When
you
want
to
return
to
14.255.0MHz, first switch back to the 14MHz band. Then
switch to "'A'' VFO
and the frequency readout wil! show
14.255.0MHz.
When recalling a memorized frequency be sure to turn OF F
the dial fast circuit.
If the circuit is not turned OFF, the
memorized
frequency's
1KHz and 100Hz digits will both
revert to "0".
RA-TB/RB-TA
These
positions
will allow you to operate split transmit/
receive frequencies on the same band.
EXAMPLE:
Set "A" VFO to 14.350.0MHz and "'B" VFO to 14.255.0
MHz.
Then
set the VFO
select switch to the RA-TB
position.
14.350MHz
will shown on the readout during
receive
("A'
VFO)
and
14.255.0MHz
during transmit
("B' VFO).
You are now receiving on 14.350.0MHz and
transmitting on 14.255.0MHz.
Setting the VFO select switch to RB-TA re
rses the above.
Changing bands in these modes resets both "A" and ''B"'
VFO to the lowest band limit.

RIT (RECEIVER
INCREMEMTAL
TUNING)
By using the RIT circuit, you
can shift the receive fre-
quency
+800Hz
either
side
of the transmit
frequency
without moving the transmit frequency
itself.
Therefore, |
when
you
get a call slightly off frequency, or when the
other station's frequency
has shifted, you can tune in the
frequency without disturbing the transmitting frequency.
By pushing the RIT switch down once (it's a spring loaded
switch) the RIT circuit is turned ON and the RIT LED is lit.
The receive frequency is shifted with the RIT knob.
When the RIT knob is in the "0" position, the transmitting
and
receiving
frequencies
are the same.
Rotating
the
control to the (+) side raises the receiving frequency, and
rotating to the (—) side lowers the frequency.
To turn OFF
the RIT control, again push on the RIT switch and the
RIT
LED will go OFF.
When the RIT circuit is OFF, the
transmit and receive frequencies are the same regardless of
