Sounds like you’re on the right track with getting tuned up. While reading your latest post I thought of something that may or may not be a slight difference between our setup. When I ordered my CHA P Loop 2.0 I also bought the optional booster kit. I don’t think I’ve ever used the small loop that came with the antenna kit other than to set it up one time and to be sure that the connectors were OK and the loop would tune. Here’s a link to the kit. http://chameleonantenna.com/MAGNETIC_LOOP_ANTENNAS/CHA_BOOSTER_KIT/CHA_BOOSTER_KIT.html If Chameleon’s data is correct, on the main page for the Loop 2.0 the efficiency is double that of the standard loop on 40-80. On 20 it’s really pretty good compared to the standard loop. http://chameleonantenna.com/MAGNETIC_LOOP_ANTENNAS/CHA_P_LOOP_2_0/CHA_P_LOOP_2_0.html I’m nit suggesting that you run right out and buy the booster kit but at QRP power or slightly higher, double the efficiency is nothing to sneeze at.
