Special Functions; Lock Detect; Squelch Detect; Audio Wait - AOR AR8000 Operating Manual

(17) SPECIAL functions

There are five "special" programmable functions available so that you may
further optimise the receivers performance.
THESE ARE FACTORY SET SO ONLY ATTEMPT TO CHANGE THEM IF
YOU ARE CONFIDENT OF THEIR EFFECT. MAKE A CAREFUL NOTE OF
THEIR CURRENT POSITIONS BEFORE YOU ATTEMPT TO CHANGE THEM
AS THE DEFAULTS SHOWN LATER ARE SUBJECT TO CHANGE.
The options are selected by holding the [FUNC] key plus a numeric key
while switching the receiver On. Wait for the sign on message to finish
before releasing the keys. This process is best achieved with the receiver
laying face upward on a table top (having 3 hands also helps!)... it is not
designed to require regular adjustment and prevents accidental changing of
values.
17-1 LOCK DETECT - [FUNC] [1] SWITCH ON
This is the length of time provided for the VCO to travel and PLL to "lock" onto
a new frequency. The shorter the time, the faster the search and scan rate.
However, the shorter the time, the less reliably the process will be.
A compromise has to be made. If you scan the extremes of the receiver's
frequency coverage and experience "PLL-ERROR" messages, it may be worth
increasing the value. The default is set to 05 milliseconds but a value of 20 is
not unreasonable. The acceptable range is 00 to 49 milliseconds.
To change the value rotate the [DIAL]. Press [ENT] to accept the changes
and return to normal display. Press [CLEAR] to abort the menu and return to
normal display.
17-2 SQ DETECT - [FUNC] [2] SWITCH ON
This is the length of time provided for the squelch to determine if a signal is
present. The longer the value the more reliable the operation but search and
scan speed may be reduced.
The default is set to 30 milliseconds. The acceptable range is 00 - 49 mS.
To change the value rotate the [DIAL]. Press [ENT] to accept the changes
and return to normal display. Press [CLEAR] to abort the menu and return to
normal display.
17-3 AUDIO WAIT - [FUNC] [3] SWITCH ON
This is the length of time provided for the squelch to determine if valid
modulation is present when using AUDIO scan and search. The longer the
value the more reliable the operation but search and scan speed may be
reduced.
