PERATION
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 control until the background noise is just si-
lenced.
3. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row 5 [ SCN , PRI , DW
] appears on the display.
4. Press the
(
DW
) key momentarily to activate Dual Watch operation (the “
DW ” icon
will appear at the bottom left corner of the LCD.
5. The transceiver will continue to monitor (squelched) on the current (VFO-A) frequency,
but every five seconds will switch briefly to VFO-B frequency, looking for activity.
6. 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).
7. Press the
(
DW
) key again to cancel Dual Watch operation (the “
DW ” icon will
disappear).
Note that pressing the
PTT
switch on the microphone does not cancel Dual Watch
operation.
