Hello Brian, I was hoping there would be a way to do this selectively within the confines of the K3 and not use something external. I found in the last 160M contest that there were many DX I could hear on the Rx antenna as it is "steerable" while the Inv-L picks up sounds equally from all directions. I found I could almost completely eliminate stateside QRM if I listened only through the Rx antenna and aimed it towards the DX but it could only be heard in one ear.
Considering the high amount of QRM coming in on the Inv-L and the high amount of desired signals coming in on the Rx, I needed to shut off the noise in the Inv-L & hear with both ears, the DX on the Rx antenna. Funny thing for me about the diversity mode; I use it but not often because of the signal loss when diversity is engaged. What I find I prefer is to link the two receivers and use the sub. This allows a better sounding signal to me and its in sync so there's no offset in the Rx. I let my head do the "diversity" and it seems to work really well. About the only time I use diversity is when there is a wide split the XIT won't reach and the DX is faint on the main antenna. Then I'll go split find a hole in the pileup, perch there and go into diversity so I can still hear the DX on their transmit freq till the band changes. The twin receivers & diversity is a very cool thing. Gary, KA1J > I have all of my receive antennas switchable into the sub RX or the rx input (a six by two matrix in my case) K9ay makes a box that can do this or you can build your own. K9ay has a preamp in his box so that there is no loss of level when both inputs are on the same antenna. The RX ant switch will toggle the main receiver between receive antenna(s) and the tx antenna. The diversity feature of listening on the same frequency with different antenna in each ear makes it possible to pick out stations in the sound field. On good nights it's really obvious when a station is not on this continent with one dash or dot. > > > On Jan 31, 2014, at 8:57 PM, "Gary Smith" <g...@ka1j.com> wrote: > > > > I connect my Rx antenna via the BNC below the SO239 outputs.
