Gary, well stated. The diversity of the K3(S) is amazing. It has eliminated use of all other rigs in my shack except for the occasional KX3/X2 updates when not in portable. Love the mode. I use a vertical and horizontal loop as the two antennas. I use the loop for transmitting.

I agree wholeheartedly with you. I had never used the APF/DUAL PB until Wayne, I believe it was, mentioned it some time back. I'd tried it in the beginning but wasn't skilled using the radio then and it was left by the wayside. I had used Diversity often and with great success, it always was a plus for me and any insertion loss was certainly either made up for by adding the preamp or at the least by the increased quality of the signal received. In my case I have the 200Hz filters in the main & Sub Rx board and often run the width down as tightly as possible and if I must, adjust the RF gain to compensate for band conditions and I don't find any ringing. If the RF adjustment is causing a loss with band conditions, I open up the width a little and still use the RF, but not as aggressively. With that, I miss nothing in there and have as tight a width as possible with excellent tone from my received signals. Add to that the magnificence of the SubRx and It's genius. I would never be without the Sub Receiver, it's to me, absolutely essential for me to copy as best is possible. Happy Thanksgiving to all who celebrate it. 73, Gary KA1J > As has been the case for the past several years the only K3 control I > touched during the CW SS was the tuning knob because there was never > any reason to futz with anything else.
