I am aging out of making a radio work by making many settings on the K3. I am considering to buy a Genovation Keypad for CW, RTTY, FT8 mode settings and others such a band and other settings on the K3. I need a mentor who is willing to guide me. In return,I will sponsor you as a member of the BIG Radio Club, upstairs. :) 73, Lou KE1F
