This brings up a question I've been meaning to ask -- what, exactly, has been going on with the receiver sound? Well before the current 1.6.2, when I set the "preamp" to Off or Low or Med or High, there was a distinct audio difference between them. Starting with 1.6.2 (probably before, I don't do all betas these days and made little use of 1.6.1), the differences are far less distinct to my ear. I do note that when I play with the "RF Gain" control on recent betas, that if I set it at "about" 80 per cent, I get something that "sounds like" the way it used to sound and at 100 per cent, it sounds about like 1.6.2 in terms of preamp settings. I kind of prefer the sharper delineations, though I don't know if, objectively, it really alters the performance the way it used to. In the old version of it, reducing from high to medium to low and (on RTTY) sometimes to off really make a marked difference in signal to noise even if the sound itself came down a bit. I know there was a lot of discussion of all of this, but what I experienced is still not quite what all those discussions (to the extent I read or understood them) would have lead me to believe. Do I want the old behavior? If so, how do I get it? Or, is there something about how the AGC now works that I get the S/N advantages, but more audio after all? Would this answer be the same for RTTY work (of which I've done less of late, but really used the sharp delineations to manage reception quite effectively)?
