Hi there Paul, Mike K2MK mentioned that & Joe, W4TV along the same line. I made up the pieces today and did as was suggested. Indeed this is exactly what I wanted to do with the K3 & the directional Rx antenna, mission accomplished. Now I can null out offending stations sometimes to the point of really not hearing them to a level that is bothersome.
There were some SOBs intentionally QRMing FT5ZM on 160 and while I didn't work him there I was able to null some of the QRM to the point I could hear him. On diversity I still heard the QRMers over his signal. (What unhappy people those QRMers must be to live every day with that defect in their thoughts, but I digress) In the absence of intentional QRM I would have been able to have heard them marvelously with diversity. My concern with the dB loss is only when it comes to the faintest of stations which is what I like to work, I like the most difficult ones to pull out because they are the most interesting ones to me; DX, QRP or someone with a really compromised location, that gives me the greatest pleasure and when such signals are in the mud, 3 dB is a lot of loss. When copying a signal that moves the meter the loss is no problem. All these options to select what antenna configuration to use with the K3 & its sub receiver are tools each has unique benefits & liabilities, sometimes a different choice lets me make the Q.
