8-7-2 Search LEVEL
The search LEVEL squelch parameter causes the AR8600 to check the signal strength and to only open
the squelch when the signal strength is above the stated level (which is programmable in 256 steps).
The limits are OFF and 1 to 255 (default off).
Search LEVEL is configured via the SRCH-GROUP menu. Use the key sequence
to access the “SRCH-GROUP” menu. Use the ï ð keys to select the
SRCH-GROUP number between 1 and 9. ò six times to display the search environment
parameter of LEVEL.
as a short cut to off (which is the default). Use the main dial to increment value
by 1 or use the ï ð 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 search
environment menu. Alternatively you may move to the next option (search VOICE squelch) by pressing
the ò key.
While searching, the LCD legend “LSQ” is displayed to indicate that search LEVEL squelch is in
operation.
8-7-3 Search VOICE
The search 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).
Search VOICE is configured via the SRCH-GROUP menu. Use the key sequence
to access the “SRCH-GROUP” menu. Use the ï ð keys to select the
SRCH-GROUP number between 1 and 9. ò seven times to display the search environment
parameter of VOICE.
