 >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.
