Dual Watch is similar, in some respects, to scanning. In Dual Watch, however, the trans-
ceiver monitors (squelched) on the VFO-A frequency while periodically checking VFO-B
for activity (or vice-versa). 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 reporting band openings on 6 meters.
To activate Dual Watch:
1. 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.
2. Recall VFO-A, then rotate the
SQL
control until the background noise is just silenced.
3. Press the [
FUNC
] key momentarily, then rotate the
SELECT
knob, as needed, until
Multi Function Row “g” [
SCN, PRI, DW
] appears on the display.
4. Press the [
C
](
DW
) key momentarily to activate Dual Watch operation (the “ ” icon
will appear at the upper of the frequency display). The transceiver will continue to moni-
tor (squelched) on the current (VFO-A) frequency, but every five seconds will switch
briefly to VFO-B frequency, looking for activity.
5. If a station is detected on the VFO-B frequency, the transceiver will pause on the VFO-
B frequency (the decimal point in the frequency will blink).
6. Press the [
C
](
DW
) key again to cancel Dual Watch operation (the “ ” icon will disap-
pear).
Pressing the PTT switch on the microphone does not cancel Dual Watch opera-
tion.
