• AGC (Automatic Gain Control)
Displays the currently selected AGC setting.
The AGC system is designed to help compen-
sate for fading and other propagation effects. The
AGC characteristics can be individually set for
each operating mode. The basic objective of AGC
is to maintain a constant audio output level once
a certain minimum threshold of signal strength is
achieved.
After touching [AGC], touch the desired time con-
stant.
● AGC can be set for each operation band.
● The “AUTO” selection mode selects the opti
-
mum receiver-recovery time for the reception
mode.

Normally, AGC is set to “AUTO”, which auto-
matically selects the time constant according to
the received signal type, but when receiving a
weak signal or when there is noise and fading,
the AGC action may be changed according to
the reception condition at that time. Change the
time constant to make received signals most
audible
Several aspects of AGC performance may be
configured via the Menu. However, because
AGC can have such a profound impact on over-
all receiver performance, we generally do not
recommend any changes to the AGC Menu se-
lections until you are thoroughly familiar with the
performance of the FTDX10.
