Have you tried these settings? It's easy to do with a signal generator. You might not like them.
From what I can tell your settings kick in the AGC at S9. At that point you have about 54db of audio change from weakest to strongest. It then goes up from there. How much depends upon how Elecraft has warped the slope so your ears don't get blown up. The AF limiter will probably kick in often and produce a horrible sounding signal to save your ears. The strategy to fiddle with AF/RF controls to keep AF levels acceptable always seemed an added chore that the radio should be doing. 73 de Brian/K3KO On 5/23/2012 00:31, Dave Hachadorian wrote: > I'll be in the WPX CW this weekend, using the rare prefix call > sign KZ7X.
