4 OPERATING BASICS

EQUALIZING VFO FREQUENCIES ([A=B])

Press [A=B] to transfer the frequency and modulation
mode of the active VFO to the inactive VFO.
A=B
1 Assume that you are presently using VFO A.
2 Press [RX B].
VFO B is selected and the frequency currently
selected by VFO B is displayed.
3 Press [A=B].
4 Press [RX A].
This selects VFO A again. Note that the VFO B
frequency and the modulation mode have been
copied to VFO A due to Step 3.

SELECTING MODE

To change the operating mode, simply press the MODE
button for the mode that you want to use. The second
function on each MODE button is accessed by pressing
the same button again.
Example: To switch to LSB, press [LSB/USB] one
time. To then switch to USB, press [LSB/USB] again.
MODE
LSB
/USB
<<<#12 (9L) >>>
CW/– R
FSK
/– R
FM/AM
The CW mode defaults to the upper sideband. The "–R"
label on [CW/–R] indicates that CW may be sent and
received using the lower (reverse) sideband if you want.
The "–R" label on [FSK/–R] indicates that the mark and
space signals for RTTY may be reversed by selecting
this mode.
In SSB mode, the transceiver automatically selects LSB
for frequencies lower than 9.5 MHz, and selects USB for
9.5 MHz or higher frequencies if the Tuning control or
Mic [UP]/[DWN] is used to cross the frequency of
9.5 MHz. This is also true if using the Front Panel [UP]
or [DOWN] button.

SELECTING FREQUENCY

There are two methods to select a frequency that are
explained in the following sections:
A Manual Tuning
Change to the correct band or use the 1MHz Step
function to get close to the desired frequency. Then
use the M.CH/VFO.CH control for coarse tuning and
the Tuning control (or the Mic [UP] and [DWN]
buttons) for selecting the exact frequency.
B Direct Frequency Entry (Keypad)
Enter the desired frequency directly using the
numeric keypad.

CHANGING BANDS

1MHz
DOWN
UP
1 If "MHz" is illuminated on the Display, first press
[1MHz] to exit from the 1MHz Step mode.
"MHz" goes out.
2 Press [UP] or [DOWN].
Holding down either button consecutively steps
the transceiver to each band.

USING 1 MHz STEPS

The default step size for the 1MHz Step function is
1 MHz; however, you can also select 500 or 100 kHz
steps via Menu No. 52 (1M/500k). Menu selections are
explained in more detail beginning on page 24.
1 Press [1MHz] to enter the 1MHz mode.
"MHz" lights.
AGC
AUTO
USB
2 Press [UP] or [DOWN].
The frequency changes up or down in 1 MHz
steps (or 500 or 100 kHz steps) each time [UP]or
[DOWN] is pressed. Holding down either button
causes the function to repeat.
