as a short cut to off (which is the default). Use the main dial to increment value by

1 or use the Õ Ö keys to increment by 10.

While adjusting level squelch, the “” legend will be displayed to the left of the value “LEVEL  3”

indicating that the current value will not cause the squelch to close. Increase the value until the “”

legend is just extinguished (this may typically be around a value of 5 - 60), the current transmission and

signals below this level will be skipped. There will be no audio produced when a transmission is

encountered below the level configured even though the “S” squelch legend is displayed. This is a

useful alternative to regular squelch on noisy bands such as short wave.

The approximate relationship between signal meter segments and level value is as follows:

1 2 3 4 5 6 7 8 9 10 11 12 13 14

8 13 18 24 29 35 39 44 50 55 58 62 71 77

Note: When level squelch is in operation, the rotary squelch control is usually best

rotated to the fully anti-clockwise position.

to accept the changes and return to the display prior to accessing the scan

environment menu. Alternatively you may move to the next option (scan VOICE squelch) by pressing

the Ø key.

While scanning, the LCD legend “LSQ” is displayed to indicate that scan LEVEL squelch is in operation.

7-8-3 Scan VOICE

The scan VOICE squelch parameter causes the AR8600 to check the current frequency for valid audio

and to only open the squelch when audio above a specified level (which is programmable in 256 steps)

is detected. The limits are OFF and 1 to 255 (default off).

Scan VOICE is configured via the SCAN-GROUP menu. Use the key sequence

to access the “SCAN-GROUP” menu. Use the Õ Ö keys to select the SCAN-

GROUP number between 1 and 9. Ø five times to display the scan environment parameter

of VOICE.

as a short cut to off (which is the default). Use the main dial to increment value by

1 or use the Õ Ö keys to increment by 10.

While adjusting voice squelch, the “” legend will be displayed to the left of the value “VOICE  12”

indicating that the current value will not cause the squelch to close. Increase the value until the “”

legend is just extinguished (this may typically be around a value of 1 to 100), the current transmission

and signals with audio below this level will be skipped. There will be no audio produced when a

transmission is encountered with audio below the level configured even though the “S” squelch legend is

displayed.
