Strange operation here... AGC-S seems to work as it should and AGC-F as expected but if I turn AGC off my rig does silent. I'm still able to see the S-meter swinging to the signal that I was listening to. Current settings are as follows: AGC Decay = Soft AGC Hold = 0.00 AGC Pulse = Normal AGC

Good but any hope for 1 dB S-meter resolution? Use Utility and issue !bd; You'll get BD(xx)00(42)00(yy) xx is indeterminate. yy is a signed hex byte that should represent dBm at the Rx antenna jack. So yy=93 - -109 dBm yy=B4 - - 76 dBm and so forth. It may be that you need to have

Is there a way to determine if the software is properly detecting the extreme signal RX protection wire other than injecting an extreme signal and seeing if it turns off the preamp? ~Brett On Wed, Aug 12, 2009 at 12:49 PM, wayne burdickn...@elecraft.com wrote: K3 beta-test firmware revision
