3. After the least significant digit has been entered
press the ENT key again to signify you want the
radio to change frequency. If you entered the
frequency down to the nearest 10 Hz a beep will
sound and the radio will automatically change to
the new frequency without the need of pressing
the ENT key for the second time.
For example;
To enter 14.200.00 MHz there are two methods:
Method one; Press [ENT], [l], [4], [2], [ENT]
Method two: [ENT], [l], [4], [2], [0], [0], [0], [0]

4. If you make a mistake while entering the
frequency and have not yet pressed the ENT key,
or entered the final digit, you may cancel the input
by pressing the CLR key or the PTT switch.
4-10-7. Dual Digital VFO’s
Operational convenience is enhanced thru the use of
two VFO’s.
Two VFO’s are provided to allow you to change
frequencies rapidly with the least amount of dial
rotation. For example; you could set one VFO to the
lower tuning limit and the other VFO to the upper
tuning limit.
A = B key
Depressing this key causes the data contained in
the inactive VFO (the VFO that is not currently
being displayed in the display area) to change to
the same data that is contained in the active VFO
(the one currently displayed). Both the frequency,
mode and filter selection are changed.
Note
When a memory channel is being used
reception, the A = B key will not function. for
For example:
RX VFO A is set at 7 MHz in LSB, and RX VFO B
is 14 MHz in USB. RX VFO A is the active VFO
(shown on the display). Depressing the A = B key
will cause RX VFO B to change to 7 MHz in LSB.
4-10-8. SPLIT FREQUENCY OPERATION
Different frequencies can be set for VFO A, VFO B
and for memory.
For example:
VFO A is the active VFO, and VFO B is the inactive
VFO. Depressing the TX VFO B key will cause the
transceiver to receive on VFO A and transmit on
VFO B. The mode of reception and transmission will
follow the mode contained in the appropriate VFO. It
is possible to work cross band, cross mode if
desired.
To avoid confusion during contest, or pile-up
operations we recommend using VFO A for receive
and VFO B for transmit.
•TF-SET key
Depressing this key will allow you to rapidly set or
check the transmit frequency, during SPLIT
operations, without the need of actually transmitting.
This key is especially convenient when you are
trying to locate the transmit frequency of the station
currently in contact with the DX station, since
depressing this key allows you to receive on the
transmit frequency as long as the key is held
depressed. The TUNING knob is active when this
key is depressed, so it is easy to change your
transmitter frequency at the same time, if necessary.
Releasing the key will return you to the original
receive frequency.
4-10-9. Interference Reduction
■All mode
[ I ] SLOPE TUNE control (Except FM mode)
During reception, these controls permit you to
reduce the apparent IF filter bandwidth and therefore
reduce adjacent channel interference.
•SLOPE TUNE HIGH CUT control
Adjust the HIGH CUT control counterclockwise,
and interference from signals higher than the
operating frequency will be reduced. The high-
frequency components of the resulting receiver
audio will also be reduced.
•SLOPE TUNE LOW CUT control
Adjust the LOW CUT control clockwise, and
interference from signals lower than the operating
frequency will be reduced. As with the HIGH CUT
control, use of the LOW CUT control will also
affect the audio frequency passband. In this case
the low frequency components of the audio signal
will be reduced.
Maximum bandwidth occurs with the LOW CUT
control fully counterclockwise, and the HIGH CUT
control full clockwise.
