Hans, thanks very much!
S-meter and AGC seem to work very well, however, as Danny noted, when transmitting, some artefacts like static can be heard on each dah or dit. With AGC disabled, these are gone.
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). Couldn't they be used as defaults after a factory reset? It would reduce the hassle involved after a reset, IMO.
Nice work, as always!
