IF Gain
The AGC can be turned off entirely, using the
AGC Off
button. The receiver
gain must then be adjusted manually. This is done using the
IF Gain
setting.
Note that by setting an excessive gain, the receiver will overload and the
demodulated signal will be distorted. On the other hand, if the gain is too
low, it will make the receiver appear “deaf”.
Manual IF Gain setting is useful for hunting for very weak signals buried in
noise.
Manual IF Gain Control
The IF Gain control is only enabled when the AGC is switched off. The gain
“value” ranges from 0 to 100, where 100 corresponds to maximum gain.
Audio AGC
The
Audio AGC
facility is available in the Demodulator panel, and provides a
supplementary function to the main AGC. (The main AGC employs a
hardware circuit, while the Audio AGC works in software.)
Audio AGC
Audio AGC is useful to compensate for audio volume changes when the
antenna signals are so weak that the main AGC is not yet activated, or when
the main AGC is disabled and the manual IF gain is used.
