Open SL's "circuit window", and turn on one of the DSP blackboxes (the small boxes labelled with a question mark). Right-click into it to open its configuration menu, and configure the AGC for your needs. Of course the spectrogram must be tapped AFTER the dsp blackbox then. If you like, I can send you a "QRSS"-configuration with the AGC enabled. (I avoid AGC wherever possible, because if it's on wanted signals just seem to fade out in the presence of stronger signals or a rising noise level. But that's personal taste.) A purely "visual" AGC like in ARGO doesn't exist yet, but as mentuined above the signal can be pre-processed in many ways before entering the spectrum analyser. Best regards, and a happy christmas time everyone. 73, Wolf DL4YHF / DK4U JO42FD .
