■ AGC function
The AGC (auto gain control) controls receiver gain to
produce a constant audio output level even when the
received signal strength is varied by fading, etc.
The transceiver has 3 AGC characteristics (time con-
stant; fast, mid, slow) for non-FM/WFM mode.
The FM/WFM modes AGC time constant is fixed as
‘FAST’ (0.1 sec.) and AGC time constant cannot be
selected.
q Select non-FM/WFM mode with [MODE].
w Select

OFF is set with one of FAST, MID, SLOW setting
in AGC set mode.
