You might be interested in the AGC input versus output performance data
I took for the K2 and several other receivers.

To some extent, the K2 already implements this feature. Whether this is
an intentional design decision or a byproduct of other decisions made
during the K2's design, I do not know. In my opinion, it is one of the
reasons for the distinct "K2 sound."

>I found a neat option on the new Orion II that seems great cw. It is
not in
the manual. It is called slope or something like that. It is the last
item
in the RX menu. It has to do with the audio and normal is flat,
probably for
SSB ? But you can set the slope to 1.1 or 2.2 db and I first tried it
on 80M
noise and didn't seem to do a thing. Naturally I said " oh well " and
later
gave it a try on cw and a BIG difference. The signal seems to pop up
out of
the noise. Neat ........... will my sometime this year K-3 have that ?
Yes, see below. 73, Bill W4ZV
KK7P:
In the menu, you can set the following parameters for AGC:
Attack time, Hold (Hang) time, Decay rate (in dB/sec for Fast and
Slow), Threshold, and Slope. Slope sets the compression you get from
AGC, whether you like everything above the threshold to be flat (S4
and 40 over S9 are the same level) or some sort of slope (2:1, 10:1
whatever) so stronger signals are somewhat louder.
