21FT-817ND Operating Manual
OPERATION
SETTING THE OPERATING FREQUENCY
1. In the “SSB/CW/DIG” modes, rotate the
knob to set the frequency. Clockwise
rotation of the knob increases the op-
erating frequency.
2. In the “AM/FM/PKT” modes, rotate the
knob to set the frequency. Clockwise rotation of the knob increases the operating
frequency.
3. You may also use the knob to adjust the operating frequency in the “SSB/CW/
DIG” modes. The knob provides faster tuning, ideal for making quick changes in
frequency when you want to move across the band in a hurry. You can then use the
knob to make fine frequency adjustments.
4. If you press the knob momentarily, then rotate the knob, you can now
change the operating frequency in 1 MHz steps, allowing very quick frequency excur-
sions. This can be particularly helpful on the VHF and UHF bands.
5. In step 2 above, it was mentioned that tuning in the “AM/FM/PKT” modes is accom-
plished using the knob. By default, the knob is disabled in these modes; if
you wish to enable the knob in these modes, use Menu #04; see page 60.
6. The synthesizer steps for the knob may be adjusted independently by mode. Use
Menu #06 for AM, #30 for FM, and #47 for SSB/CW/Digital. See pages 60, 64, and 67
for details.
The main knob synthesizer’s tuning rate (the number of steps per rotation
of the knob) can be adjusted using Menu #33. See page 65 for details.
STACKED VFO SYSTEM
1. Press the key momentarily, then rotate the knob, as needed, until Operating

appears on the display.
2. Now press the
(
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 pre-
served, along with the frequency information, on each VFO.
