■ 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.
DD
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.
• Push and hold for 1 sec. to turn the AGC
function OFF.
DD
Adjusting the AGC time constant
q Select any non-FM mode.
w Push , then rotate [AGC] control to adjust
the AGC time constant.
• [AGC VR] indicator above the switch lights green.
DD
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 constant
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] for 1 sec. to select a default
value.
t Push [AGC] (MF5) to select medium time constant.
y Rotate the main dial to set the desired time constant
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] 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 constant
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] for 1 sec. to select a default
value.
o Select another non-FM mode. Repeat steps e to i
if desired.
