Has anyone looked at the harmonics on their 49er.? I must admit that my testing method is primitive but looking at the 2nd and third harmonics on my K3/P3 panadapter, the 2nd and 3rd harmonics on mine are progressively stronger than the fundamental.? I have my 49er (Frog Sound) xcvr terminated in a 50 ohm dummy load sitting on the desk next to my K3 that is terminated in either another 50 ohm dummy load or a ground mounted vertical antenna that is roughly 30 feet or so from the K3.? In both cases, the harmonics on 20 and 15 meters are stronger that the 40 meter signal, somewhat stronger on 20 meters and much stronger on 15.? Has anyone else checked this?
