The higher the AGC reference level, the stronger will be the signal at the input
of the demodulator. If this level is too high and the input signal too strong,
distortion may appear. On the other hand, decreasing the AGC reference level
will generally result in lower audio levels.
While in the automatic gain mode, the actual momentary gain will be shown
next to the word
Gain
- as can be seen in the following illustration.
By using the
Max. gain
control it is possible to limit the maximum gain that the
AGC has at its disposal, and preventing an excessive “pumping noise”
between transmissions. This is especially useful with SSB signals or when
monitoring point-to-point transmissions where the transmitter is switched on
intermittently.
In such cases, if the maximum gain was not limited, the AGC may tend to
increase the maximum gain too much, which could result in unpleasant noise
bursts between transmissions. By limiting the maximum gain, such noise
bursts can be reduced or eliminated.
Manual Gain
The
Manual gain
mode can be enabled using the
Manual
button, which is
mutually exclusive with the
AGC
button. In this mode, the gain can be adjusted
manually to the desired value using the
Gain
control drop-down:
