Laurentino sent his modifications to me, and they will be rolled into the
b3 release of nqcc (probably late this week).
As for AGC, this is probably more about RF design that you wanted to know....
It is fairly common to design an FM radio receiver with a variable gain
amplification stage that is controlled by a feedback loop from a signal
strength indication. This type of feedback is sometimes called Automatic
Gain Control. At some point this is simply a bias voltage to an
amplifier, which is apparently what the AGC value in CyberMaster tell
you. It will correspond the the strength of the received signal. The
relation between millivolts and signal strength is specific to the radio
amplifier stage.
In simpler terms, the AGC value should correlate to the strength of the
recieved radio signal (although I can't say whether higher numbers mean
stronger signal or weaker).
