VFO, displayed on the frequency display, and stored іп "В" memory.
3. RA-TB: The receive frequency is controlled by "А" VFO and the transmit frequency is
controlled by "В" VFO. Both frequencies are stored in their respective memories, and
displayed during their respective operation times ("A'" frequency during receive, and "В"
frequency during transmit).
4. RB-TA: The receive frequency is controlled by "В" VFO and the transmit frequency 15
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).
NOTE: The MS, 1, (2), and positions are described in the "MEMORY CHANNEL OPE-
RATION" on page 18.
Ш When the IC-260A/E is first turned ON, 145.000.0MHz is preset into the "А" VFO and
145.600.0MHz is preset into "B" VFO.
FOR EXAMPLE:
When the VFO/MEMORY Switch is set in the "A" position and the set is turned ON, 145.000.0
will be displayed on the readout. This will occur whether the VFO/MEMORY Switch is in either
the "A" or "RA-TB" or Memory Channels positions.
When the VFO/MEMORY Switch is set in the "В" position or "ВВ-ТА" position, 145.600.0 will
be displayed on the readout. Rotating the tuning knob clockwise will increase the frequency, and
rotating the tuning knob counterclockwise will decrease the frequency in 100Hz steps. (5KHz
steps in the FM mode)
Ш Switching from one VFO to the other VFO does not clear the first VFO. The frequency is
retained in the VFO's memory.
FOR EXAMPLE:
When the VFO GANG Switch is set in the "SEP" (pushed IN) position, if 145.125.0MHz is set
with "A" VFO, and the VFO switch is set to "В" VFO, the frequency readout will show "В"
УРО" frequency, but 145.125.0MHz is still stored іп "А" VFO's memory. Returning the VFO
Switch to "A" VFO position, and 145.125.0 will be displayed on the readout. Accordingly, if the
switch is placed in the "B" VFO position, the frequency that was set with the "В" 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 "А"
and "B" VFO. It also allows you to search for a clear 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!
