FT-920 Operating Manual

A) while periodically checking the Sub VFO (typically
VFO-B) for activity. A typical example might be for
you to set VFO-A to 50.110 MHz, watching for DX
stations who might call CQ on that frequency, while
periodically checking 28.885 MHz for stations report-
ing band openings on 6 meters.
To activate Dual Watch:
Q Set up transmit and receive operation on VFO-A,
establishing your primary monitoring frequency.
Set up the frequency to be checked periodically
on VFO-B.
R Verify that the correct antenna (A or B) has been
selected for VFOs A and B, if they are on different
bands. The Dual Watch feature will automatically
switch antennas for you during the VFO-A/B
switching process.
S Rotate the [SQL] control until the background
noise is silenced.
T Press the [DW] key. The decimal points in both
frequency displays will blink, and you will observe
that, every few seconds, the green “RX’ indicator
for VFO-B will become illuminated for an instant.
This shows you when VFO-B is being checked
for activity.
U If a station is detected on the VFO-B frequency,
the FT-920 will pause on the VFO-B frequency,
and stay there according to the Menu selections
you made per the “Scan-Resume Choices” ear-
lier.
V Press [DW] again to cancel Dual Watch. Note that
pressing the [PTT] switch on the microphone does
not
cancel Dual Watch operation.
The time interval between Dual Watch excursions to
VFO-B may be adjusted, via Menu Item U-18, to any
value between 3 and 15 seconds. The default setting
is 10 seconds.
The VFO-A register need not be in the “VFO” mode;
it may also be set to a Memory Channel or a QMB
channel, if you like.
Note also that the active R
X VFO at the time that [DW]
is pushed will be the one on which the transceiver
will hold, checking the opposite VFO periodically.
Therefore, if the green “RX” LED for
VFO-B
is illumi-
nated when you push [DW], the FT-920 will hold on
VFO-B, then check
VFO-A
periodically for activity.
Remember that the squelch must be engaged in or-
der for Dual Watch to function. During Dual Watch,
transmitting remains enabled, and the VFO frequen-
cies may be changed.
The FT-920’s Menu System allows you, the owner,
to customize a wide variety of transceiver perfor-
mance aspects and operating characteristics. Such
