FOR EXAMPLE:
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:
If 145.125MHz is set with "A" VFO, and the VFO switch is set to "B" VFO, the frequency
readout will show "B" VFO's frequency, but 145.125MHz is still stored in "А" VFO's memory.
Returning the VFO Switch to "A" VFO position, and "5.125" 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 a clear frequency with one VFO,
while keeping your operating frequency on the other VFO. When you have found a clear fre-
quency, 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!
TRANSFERING VFO FREQUENCY
FOR EXAMPLE:
DUPLEX (REPEATER) OPERATION
The SIMPLEX/DUPLEX Switch and DUPLEX MODE Switch allow DUPLEX (repeater) operation.
