87FT-857 Operating ManualDUAL WATCH OPERATIONDual 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-Bfor activity (or vice-versa). A typical example might be for you to set VFO-A to 50.110MHz, watching for DX stations who might call CQ on that frequency, while periodicallychecking 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 monitoringfrequency. 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, untilMulti Function Row “g” [SCN, PRI, DW] appears on the display.4. Press the [C](DW) key momentarily to activate Dual Watch operation (the “ ” iconwill 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 switchbriefly 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.SCANNING OPERATION
