John, you will have a lot of fun with the KX1. I am getting ready to go on the Auto Train next Sunday to Fla and getting my KX1 ready to go. I have 26ft of #26 Silky wire for a antenna and 32 ft wire for counterpoise... Also have the Super Antennas MP1 Vert. that I will take with me. Paul Gates K1 #0231 KX1 #1186 XG1 [EMAIL PROTECTED]
