Re: ND6T AGC Troubleshooting

Hi Armin,
I developed this AGC because all of the others act on the audio signal.
When the signal is really large, the audio is already distorted so we
just control a distorted signal. Please see the Attachment.

To get an idea of how well this type of AGC will work on your radio,
remove R-12 and replace it with the FET as shown in the schematic,
with just the 10K resistor going to the gate.
Using a 10K pot, connect it across 5v and connect the wiper to the Gate resistor.
As you turn the pot, it will vary the RF gain.

Have fun...
Rich

Hi Rich,

I‘m interested in your AGC controller. Is it possible to get the circuit diagram or some more infos?

kind regards
