Vertex Standard FT-857 Manual Do Utilizador

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).
