I would like to buy a KAT2 tuner built or unbuilt. I also am willing to sell my KPA100 if someone needs it. Now that the k3 is my main rig, I am turning my K2 back into my main QRP rig for travel. I can make immediate payment and accept payment through Paypal. I am also willing to trade these items...thanks and 73, Ci Jones, WU7R
