Mode Selection - Yaesu FT-920 Operating Manual

To engage the receive-only antenna, press the R
A switch, located immediately under the A/B
NTENNA
switch just described. Press the R
second time to return receive operation to the main
(transmit) antenna (A or B).
The antenna selection (A, B, and/or R
maintained in the VFO or memory register in use.
Therefore, once you have set the transceiver up
on each band of interest, you will not have to se-
lect the antenna manually (unless you want to
change it) when you change bands or memories;
the most recent setting will be retained.

Mode Selection

Press one of the Mode
switches, located immedi-
ately to the left of the VFO-
A Tuning Dial, to select the
operating mode. The avail-
able choices are SSB, CW,
AM, FM, and D .
ATA
The SSB switch is a toggle
function which allows the op-
erator to choose between
USB (used, by convention,
above 10 MHz) and LSB
(used below 10 MHz). Press the SSB switch, as nec-
essary, to choose the appropriate SSB mode as we
proceed with exploration of different bands.
The CW switch uses a toggle function to select be-
tween USB- and LSB-side injection (a.k.a. "CW-Re-
verse"). Although the default USB-side injection is
typically used, you may wish to elect LSB-side injec-
tion below 10 MHz, particularly if you anticipate switch-
ing between LSB (voice) and CW frequently.

Special Note for CW Mode
Reverse CW Sideband
When you switch modes between CW and USB,
you will observe that the frequency of the re-
ceived signal stays the same (even though the
displayed frequency may change slightly).You
will also observe that the pitch of the received
signal decreases as you increase the frequency
by rotating the Tuning Dial.
However, switching from CW to LSB requires
retuning the desired station. This can be par-
ticularly inconvenient when working a station in
the 75-meter voice band (LSB) and you ask him
to move to CW on the same frequency.
To eliminate the need for retuning in this situa-
tion, you may switch the receiver CW carrier
injection point to the "reverse" (LSB) side. When
you press [CW], you should notice that the "USB"
indicator (just above "CW" on the main display)
will blink for a couple of seconds, while the "CW"
indicator glows steadily. This indicates that USB-
side injection is currently in use. If you press[CW]
once more, the "LSB" indicator will now blink,
informing you that LSB-side injection is now in
use.
When using LSB-side injection, you can freely
switch between CW and LSB without having to
retune the other station. Note that, in the LSB
and CW/LSB modes, the received signal pitch
now increases as
you increase the
VFO frequency.
To return the re-
ceiver to the (de-
fault) USB-side in-
jection method, just
push [CW] again.
Operating Hint - An added benefit of this fea-
ture is the potential to eliminate interference. If
you are experiencing QRM from a CW station
that the IF Shift and/or DSP are unable to elimi-
nate, you should try switching to the reverse CW
sideband, retuning the desired CW signal, and
adjust the IF Shift and/or DSP again.
