The default frequency step size when turning the
Tuning control to change the frequency is 10
Hz for SSB/ CW/ FSK, and 100 Hz for AM/ FM.
However, you can change the frequency step size
to 1 Hz for SSB/ CW/ FSK, and 10 Hz for AM/ FM.

The default Tuning control adjustment rate is 500.
This represents the number of pulses the Tuning
control generates in a complete revolution. Each
pulse changes the tuning frequency based on the
current frequency step size (the frequency step
size for the Tuning control is 10 Hz for SSB/ CW/
FSK and 100 Hz for AM/ FM). For example, in
SSB mode the frequency step size is 10 Hz, so the
frequency would change by 5,000 Hz in a complete
revolution of the Tuning control. The adjustment
rate of the Tuning control can be lowered to 250
pulses per revolution or increased to 1000 pulses
per revolution.

2 Press [M.IN]/ [SCAN (SG.SEL)] to select “250”,
“500”, or “1000” (default).

This function allows you to copy the frequency and
modulation mode of the active VFO to the inactive
VFO.
1 Select the frequency and mode on VFO A or
VFO B.
2 Press and hold [A/B (A=B)].
• The frequency and mode selected in step
1
are duplicated to the inactive VFO.
3 Press [A/B (A=B)] to confirm that the frequency
was copied to other VFO.

RIT provides the ability to change your reception
frequency by ±9.99 kHz in steps of 10 Hz without
changing your transmission frequency. If the Fine
Tuning ([FINE (F.LOCK)]) function is ON, the
frequency step size becomes 1 Hz (±9.999 kHz). RIT
works equally well with all modulation modes and
while using VFO or Memory Recall mode.
1 Press [RIT].

“ ” and the RIT offset appear.
2 If required, press [CL] to reset the RIT offset to 0.
3 Turn the RIT/ XIT control to change your reception
frequency.
4 To turn RIT OFF, press [RIT].
• The reception frequency is returned to the
frequency that was selected prior to step 1.
Note: When storing the frequency in a Memory channel with
the RIT function ON, the RIT offset frequency is added to or
subtracted from the VFO frequency. The calculated data is then
stored in the Memory channel.

When using a mode other than FM, AGC selects the
time constant for the Automatic Gain Control circuit.
Selecting a slow time constant will cause the receiver
gain and S-meter readings to react slowly to large
input changes. A fast time constant causes the
receiver gain and the S-meter to react quickly to
changes in the input signal. A fast AGC setting is
particularly useful in the following situations:
• Tuning rapidly
• Receiving weak signals
• Receiving high-speed CW
For your convenience, the following default AGC time
constant has already been programmed.
SSB: Slow (“ ”) CW: Fast (“ ”)
FSK: Fast (“ ”) AM: Slow (“ ”)

You can pre-set up to 20 values (1 ~ 20) for the
FAST/SLOW time constant (release time).
To change the default time constant:
1 Press [AGC/T (SEL)] to select FAST or SLOW.
• The AGC time constant icon appears on the
display (“ ”: Slow, “ ”: Fast).
2 Press and hold [AGC/T (SEL)] to display the
time constant pre-set value.
3 Turn the MULTI/CH control to set your desired
time constant value.
4 If you want to turn the AGC OFF, press and
hold [CW T. (AGC OFF)].
