OTHER FUNCTIONS
■ Squelch delay
During operation, received signal strength often fluctuates.
This can result in annoying repeated opening and closing of
the squelch during reception of the same signal. The trans-
ceiver has a built-in squelch delay function which helps pre-
vent this. When both stations are operating from a fixed
location e.g. during packet operation, this function should be
set to “short.”
