Automatic Simplex Checker (ASC)
The Automatic Simplex Checker function was
developed as an enhancement of the Reverse
function. ASC automatically monitors the signal
strength on the repeater input frequency of the
station you are contacting. If their signal strength is
high enough to allow direct communication without a
repeater, an indicator on the Display begins blinking.
This alerts you to move off to a private frequency
and release the repeater for other users.
Press [REV] (1 s) to switch the ASC function ON.
+ Areverse video "R" appears above the operating
frequency when the function is switched ON. If
direct communication is possible without the
repeater, the "R" begins blinking. The "R" stops
blinking and remains ON steadily when the other
station's signal is too weak for direct contact
without a repeater.
+ The default is OFF.
To cancel ASC, press [REV].
Note:
@ ASC does not function if your transmit and receive
frequencies are the same (simplex operation). The reverse
video "R" remains ON.
@ While ASC is functioning, receiver audio is momentarily
interrupted approximately every 3 seconds to allow automatic
checking to take place.
@ ASC can also be used after a split memory channel has been
recalled.
