Very interesting results, in particular the AGC performance curve. I wonder about the statement "In an ideal receiver, once the threshold point is passed, there will be little or no change in audio output with changes in signal level." The way people speak so highly of the AGC action of their K2s seems to contradict this. But then maybe this is called the ideal curve just because it is easy to comprehend and draw for engineers. I have worked enough with acoustics and psychoacoustics to have great respect for the ear and our hearing. It is a very subtle instrument that is not so easy to quantify in a simple curve. Maybe design of AGC characteristics could learn something from the psychoacoustics that is built into all modern sound coders, like mp3 and its descendants? 73 Sverre LA3ZA Unofficial Guide to K2 Modifications http://www.qslnet.de/member/la3za/K2/mod.html -- I am using the free version of SPAMfighter for private users.
