AGC function

The AGC (auto gain control) controls receiver gain to
produce a constant audio output level even when the
received signal strength varies greatly.
The transceiver has 3 preset AGC characteristics
(time constant: fast, mid, slow) for non-FM mode.
The FM mode AGC time constant is fixed as
'FAST' (0.1 sec.) and AGC time constant cannot
be changed.

D Selecting the preset value

q Select any non-FM mode.
w Push [AGC] (MF5) several times to select AGC
fast, AGC medium (MID) or AGC slow.

D Setting the AGC time constant preset value

q Select any non-FM mode.
w Push and hold [AGC] (MF5) for 1 sec. to enter
AGC set mode.
e Push [AGC] (MF5) several times to select FAST
time constant.
r Rotate the main dial to set the desired time con-
stant for 'AGC FAST.'
• AGC time constant can be set between 0.1 to 8.0 sec.
(depends on mode) or turned OFF.
• Push and hold [DEF] (F-4) for 1 sec. to select a default
value.
t Push [AGC] (MF5) to select medium time con-
stant.
y Rotate the main dial to set the desired time con-
stant for 'AGC MID.'
• AGC time constant can be set between 0.1 to 8.0 sec.
(depends on mode) or turned OFF.
• Push and hold [DEF] (F-4) for 1 sec. to select a default
value.
u Push [AGC] (MF5) to select slow time constant.
i Rotate the main dial to set the desired time con-
stant for 'AGC SLOW.'
• AGC time constant can be set between 0.1 to 8.0 sec.
(depends on mode) or turned OFF.
• Push and hold [DEF] (F-4) for 1 sec. to select a default
value.
o Select another non-FM mode. Repeat steps e to
