I like to listen to a receiver with the rf gain set to just below antenna atmospheric noise and AGC on - and not raising the rf gain when it is switched on.
My K3 is srl 46xx and the only way I get the quiet background I desire is to turn the AGC off. This necessitates having the AF limiter turned on to save my ears and hopefully the speaker output chip. I've played around with various AGC settings and in particular the AGC THR - which if it would go 2 or 3 points lower would appear to address the problem. Anyway, to save a thousand words, this recording sets the scene http://tinyurl.com/38qo9ud - made from Main Rx on 3670khz with 2.8khz filter passband set to Normal, NR and NB Off. Sub Rx is identical in performance in this respect. In all other respects that I use it the K3 is a stunner.
