Hello,

at least in some cases I can confirm Sinisa's observations. A sufficiently high AGC threshold (probably in combination with some hang time) improved readability at least on some signals, f.ex. on 30m, which is a horribly noisy band at my QTH. Tested it only a few times this evening, got my ORION today....

I've tried this test many times.  I do not hear the weak signal distortion
with an AGC decay time of 20db/sec and a hang time of 0.35 and a threshold

signals.



Than can work to some degree, you are using hang time to reduce the frequency of gain changes saving you from some of the distortion.

Perhaps you have a much better behaved noise than I have :-)
These setting used here clearly result in noise clipping,
not as severe as with zero hang time, but still present.
