6. Gaze Time: Gaze represents the interval - in seconds - the receiver will wait for a
signal to appear on a quiet frequency before moving to the next. Longer Gaze times are
useful when searching for CW, SSB, and some digital-mode signals where short pauses
or gaps may be present. Short Gaze times are preferred for carrier-based signals such as
AM and FM.
To enter a new Gaze Time, advance the Edit Knob clockwise to the Gaze prompt. The
Gaze interval is continuously adjustable from 0.01-29.9 seconds. Use the main keypad to
keystroke in a three number entry (0.01, 1.20, 5.00, 10.0, etc.). The entry will self-
complete automatically when the third number is keystroked in:
At this point, PScan setup is complete. Rotate the Edit Knob in either direction to review
entries, or exit PScan Setup. To exit, press the Setup button. The Setup and PScan LEDs
will go out, and the Memory/Scan display will go dark until a new Memory/Scan function
is initiated.
4-36 INITIATING PSCAN: Once scanning parameters are set up, ensure the Setup
button is off before attempting to begin the scan run. Also, to reduce background noise
or to eliminate undesirably weak stations, set the receiver's Squelch control to a desirable
threshold level (much as you would to quiet a FM scanner receiver). Setting the Squelch
control above the background noise is especially important when using Infinite Dwell,
since background noise alone could permanently halt the scan from progressing.
To initiate a PScan, press the PScan button once. The LED will illuminate and the
Memory/Scan display will show the PScan function, F1 frequency, and Dwell Time (see
below):
With each advancing step in the scan sequence, the Aux Parameter display and main
frequency display will update to show operating parameters and operating frequency. To
may halt the scan temporarily at any point, press the Pause button twice. Pressing it a
second time will resume scanning.
If Infinite Dwell has been selected, reception of any continuously transmitting signal
sufficiently strong to open the Squelch will halt the scan. To resume scanning, press
Pause twice. To insert a Frequency Lockout to eliminate the signal on future passes, refer
to section 4-37 (Frequency Lockouts) below.
