Hi Guy et All, Sure enough this only happens using an external speaker, the headphones work fine. Sorry for not seeing this earlier.
I do have SPKRS set to 1. So it appears that when using diversity one must use Stereo speaker output and or Headphones. Mystery solved, Thanks for the quick answers 73 Dave Anderson, K4SV Tryon, NC 828 777-5088 www.K4SV.com ----- Original Message ---- From: Guy Olinger K2AV <olin...@bellsouth.net> To: "Dave Anderson, K4SV" <davek...@yahoo.com> Sent: Wed, December 15, 2010 9:08:41 PM Subject: Re: [Elecraft] Audio Nulling in my K3 in Diversity The main ways of getting audio nulling on diversity are setting CONFIG:SPKRS to 1, or having the left and right speakers actually shorted out somehow, or getting one speaker cable to one speaker flipped, and the other not. Any of those? 73, Guy On Wed, Dec 15, 2010 at 8:55 PM, Dave Anderson, K4SV <davek...@yahoo.com> wrote: > Hi All, > > For the last few weeks I have used the Diversity on the low bands with good > success. > > Tonight I came into the shack and found my K3 acting strange.
