Scan-Resume Choices; Dual Watch Operation - Yaesu FT-100D Operating Manual

Scanning Operation
SCAN-RESUME CHOICES
Scanning operation requires that you have the FT-I00D's audio squelched. The trans-
ceiver then "assumes" that the opening of the squelch corresponds to the discovery of a
signal you may wish to listen to.
Once the scan has been halted, one of three things may happen:
o
The default action is that the transceiver pauses on the signal and stays locked on its
frequency for five seconds. Thereafter, scanning will resume whether or not the
other station's transmission has ended. The pause time is adjustable from 0 to 10
seconds via MENU #05 (RESUME)
o
Another option is that the scanner will halt until the other station's transmission
ceases (at which point the squelch will close). One second after the squelch closes,
scanning resumes automatically.
o
Another option is that the scanner will find a signal, and lock on that frequency
without resuming the scan.
The above scan-resume choices may be selected via MENU #03 (SCAN MODE). See page 84.
DUAL WATCH OPERATION
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. A typical example might be for you to set VFO-A to 50.110 MHz, watching for
OX 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, as needed, to recall Operating Function Row 4 [SKP, SCN,
OW, SCH), then press the [C)(OW) key momentarily to activate
DUAL WATCH
opera-
tion (the "OW" icon will become Bold).
4. The FT -1000 will continue to monitor (squelched) on the current (VFO-A) frequency,
but every few seconds will switch briefly to VFO-B frequency, looking for activity.
The polling interval can be changed via MENU #06 (D W- TIME).
5. Ifa station is detected on the VFO-B frequency, the FT-lOOO will pause on the VFO-
B frequency, and stay there according to the settings of MENU #03 (SCAN MODE) and
Menu #05 (RESUME).
6. Press the [C)(OW) key again to cancel
DUAL WATCH
operation (the "OW" icon will
return to its original (non-bold) state). Note that pressing the PTT switch on the micro-
phone does not cancel
DUAL WATCH
operation.
