9951

Scan/sweep-stop signal level

 

When the receiver detects a signal whose level is stronger than the preset level

 

it stops scanning and receives the signal. The setting on system code 9955 is

 

available only when “0” (SQ working condition) is selected here.

 

Setting range: 0 (Squelch working condition is effective as set on code 9995),

 

1-10 (S-meter level); Factory setting 3

9952

Scan/sweep-stop time

 

When a signal is detected, the receiver stops scanning/sweeping and dwells on

 

this channel frequency. When “0” (RX) is selected, the receiver keeps receiving

 

until the traffic goes out of this channel frequency. Define the dwell time

 

between 1 and 99 s.

 

Setting range: 0 (RX), 1-99 s; Factory setting 2

9953

Sweep width setting range: 0.01-30000.00 kHz; Factory setting 100.0

9954

Sweep step frequency

 

Setting range: 0.01-30000.00 kHz; Factory setting 1.00

9955

Squelch activation

 

“Squelch activation” is the method by which the squelch is activated.

 

Setting range: 0, 1, 2, 3; Factory setting: 3.

 

0: Voice

 

The squelch is opened by signal frequency less than 1000 Hz (factory setting).

 

This frequency can be changed between 500 - 2000 Hz on system code 9958.

 

The loudspeaker reproduces a sound when the signal is lower than the preset

 

frequency.

 

Squelch OPEN:

 

Audio signal is detected and a sound is reproduced through the loudspeaker.

 

Squelch CLOSED:

 

No input signal but only noise is coming into the receiver. The receiver is

 

muted.

 

1: Level

 

The squelch is activated depending on “signal strength”. The factory setting is

 

“5”. You can change the level between 0 - 10 on system code 9956.

 

2: And

 

The squelch opens when both “voice” and “signal strength” meet the setting.

 

3: Or

 

The squelch opens by either “voice” or “signal strength”, whichever meets the

 

setting.

9956

Squelch level. Setting range: 0-10; Factory setting 5.

9957

Squelch delay - a delay until the squelch mutes (closes) the receiver after the

 

signal has gone.

(Ex) 9957: 1000 ms

Squelch closes 1000 ms after the signal has gone.

Setting range: 500-4000 ms; Factory setting 1000 ms.
