Dick, well I rewound the ouput transformer. Again I have problems, and when checking the signal on a spectrum analyzer I found that it is peaking on the second harmonic. So it transmits the main signal on 272kHz......... 136kHz is also present at the ouput, but much much weaker. It really makes me puzzling. Double trouble. Are you certain of the windings being correctly phased for "push-pull"? You may have made a "push-push doubler"??? 73, Bob |
