Hello all. I am not sure if this question applies to the list, but if any of the gurus out there can help, it would be much appreciated. I have built a remote ATU to use at the base of a 66-foot vert

At 160 meters the antenna is an 1/8 wave and need base inductive loading. On 80 meters it's at or near 1/4 wave resonance. On 40 meters it's an end-fed half wave, with a *very* high Z feed. It is lik

One little thought came to mind. Is it possible that the diode actually makes the problem worse, by rectifying the RF that is picked up by the relay and giving the coil a DC current? Maybe the capac

Hello Andy. Thanks for your mail. I will try to isolate the relay coil as much as possible. If that doesn't work, I will try a high-voltage/RF open frame relay. Some people from the list have reporte
