[AM STEP] for AM, No-052 [FM STEP] for FM, and No-082 [SSB STEP] for SSB/CW/Digital. See pages 54, 57, and 59
for details.
If you press the MEM/VFO CH knob momentarily, then rotate the MEM/VFO CH knob, you can now change the
operating frequency in 1 MHz steps, allowing very quick frequency excursions. This can be particularly helpful on the
VHF and UHF bands.
In step 2 above, it was mentioned that tuning in the “AM/FM/PKT” modes is accomplished using the MEM/VFO CH
knob. By default, the DIAL is disabled in these modes; if you wish to enable the DIAL in these modes, use Menu Mode
No-004 [AM&FM DIAL]; see page 54.
The main DIAL synthesizer’s tuning rate (the number of steps per rotation of the DIAL) can be adjusted using Menu
Mode No-035 [DIAL STEP]. See page 56 for details.
Stacked VFO System
Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “a” [A/B, A=B,
SPL] appears on the display.
Now press the [A](A/B) key to toggle between the “A” and “B” VFOs. There are two such VFOs provided on each
Amateur band, so you may set VFO-A to the CW sub-band, and VFO-B to the SSB sub-band, if you like. The operating
mode will be preserved, along with the frequency information, on each VFO.
When changing bands on either the “A” or “B” VFO, the two VFOs do not change bands together. This facilitates split-
band operation, such as on FM satellites.
Receiver Accessories
Locking Front Panel Controls
The front panel LOCK button allows you to disable the DIAL and/or the front panel controls.
In the transceiver’s default configuration, pressing the LOCK button disables just the DIAL, while the other keys and
switches are unaffected.
To lock out the remainder of the controls and the MEM/VFO CH knob, use Menu Mode No-054 [LOCK MODE];
1. Press and hold in the [F] key for one second to enter the Menu mode.
2. Rotate the MEM/VFO CH knob so as to recall No-054 [LOCK MODE].
3. Rotate the DIAL to select the desired configuration:
DIAL:
Locks DIAL knob only.
FREQ:
Locks front panel keys and knobs related to frequency control (such as BAND(DWN) and BAND(UP)
key, [A](A/B) key., etc.)
PANEL:
Locks all front panel keys and knobs (except POWER and LOCK keys)
