■ Changing Step Sizes
Select the step size that you prefer for the
M.CH/VFO.CH control via Menu No. 43 (CH. STEP).
Available step sizes are 1 kHz, 5 kHz and 10 kHz.
The default is 10 kHz.
Within the AM broadcast band, the step size
automatically defaults to 9 kHz (U.S.A./ Canada
versions: 10 kHz) for the AM mode. This step size
can be switched between 9 (ON) and 10 kHz (OFF)
via Menu No. 42 (BC. STEP). Selecting OFF in
Menu No. 42 allows you to use the step size
specified via Menu No. 43 (1, 5, or 10 kHz). While in
the AM broadcast band, changing the step size via
Menu No. 42 will change the selected frequency to
the nearest broadcast channel on the next use of the
M.CH/VFO.CH control.
If you enjoy listening to international shortwave
broadcasters, the M.CH/VFO.CH control is also the
best way to manually scan these bands. Select the
5 kHz step size via Menu No. 43 (CH. STEP) since
most shortwave broadcasters are spaced 5 kHz
apart. Set Menu No. 44 to ON. To listen to a
broadcaster on a channel that is not a 5 kHz
multiple, use the Tuning control to zero-in to the
exact frequency.
FINE TUNING
For SSB, CW, and FSK modes, the Tuning control
normally tunes through 10 kHz per revolution of the
control. For FM and AM modes, one revolution of the
Tuning control changes the frequency by 100 kHz.
These tuning rates can be halved via Menu No. 41
(F.STEP).
In addition, the Fine Tuning function reduces the step
size of the Tuning control further which allows you to
tune more slowly and precisely.
Press [FINE].
• “FINE” lights.
• The Fine Tuning function toggles ON and OFF each
time [FINE] is pressed.
QUICK CHANGES
To move up or down in frequency quickly, use the
M.CH/VFO.CH control.
•Turn the M.CH/VFO.CH control clockwise to
increase the frequency; counterclockwise to
decrease the frequency.
Due to the large step sizes available, you can quickly
move across the band. When the minimum or
maximum receive frequency for the transceiver is
reached, turning the M.CH/VFO.CH control will not
decrease or increase respectively the frequency.
Menu No. 44 (STEP.ADJ) affects how the
M.CH/VFO.CH control tunes. When Menu No. 44 is
ON (default), rounding occurs on the first step (“click”) of
the M.CH/VFO.CH control as shown below:
Example 1: Menu No. 44 (STEP.ADJ) is ON
• Menu No. 43 (CH. STEP): 10 kHz step size
• Selected frequency: 14.261.73 MHz
Turning the M.CH/VFO.CH control clockwise one step
changes the frequency to 14.270.00 MHz, and one
more step changes the frequency to 14.280.00 MHz.
The rounding occurred on the first step.
Similarly, with 14.261.73 MHz selected, turning this
control counterclockwise one step changes the
frequency to 14.260.00 MHz, and one more step
changes the frequency to 14.250.00 MHz. Again, the
rounding took place on the first step.
Example 2: Menu No. 44 (STEP.ADJ) is OFF
• Menu No. 43 (CH. STEP): 10 kHz step size
• Selected frequency: 14.261.73 MHz
Turning the M.CH/VFO.CH control clockwise one step
changes the frequency to 14.271.73 MHz, and one
more step changes the frequency to 14.281.73 MHz.
No rounding occurs.
With 14.261.73 MHz selected, turning this control
counterclockwise one step changes the frequency to
14.251.73 MHz, and one more step changes the
frequency to 14.241.73 MHz. Again, no rounding
occurs.
