Hi Bill et al
?
I got 17 loaded just fine.? Anyone have suggested AGC settings to start with?

"I configured AGC with the values seen in your screen captures, they seem pretty sane, I only changed "Recovery dB/s" (from 10 to 15) and "Threshold S" (from 8 to 7)."?
I think that is reasonable...?
I remind all that:
I was being a little extreme perhaps in my settings, because I wanted to see what goes on, during my development and testing
I had long hang time and slow recovery dB/second because again, I wanted to see what was going on, and be able to demonstrate in the video?
My video test case was also extreme... S9+30dB... to demonstrate the extreme capability of the AGC system to totally delete any possibility of that massive signal reaching the earphones, in this case it instantly applied about 36dB attenuation, and no blip at all is seen on the Audacity software's recording of the audio (which is also streamed over the USB sound card interface concurrently to the audio output). And also to clearly show everything for the video.?
My 40m noise floor is too high here right now, as I said on the video, my antenna fell down. It doesn't work as well lying on the roof which has a metal frame inside the tiles.?
Easter egg: If you press the D key on the terminal screen, in the main menu, you get my secret "lab", it's my playground which I use during development of my various functional additions, and for debugging, etc. What's in there now is some debug info on the AGC as that's the task I had most recently on the lab bench. Might be interesting, if you are wanting to play with the AGC.?
