While the bulk charge separation is "DC" in the cloud, the generator of the "DC" is friction between particles within the cloud... This rubbing of aerosol and droplet particles causing electron trans

I have not in the decades past paid any attention to 75/80 meters other than just another band to make Q's during a contest... Pushing on towards my seventh decade of life I have finally made some ch
On this subject, ON4UN states on page 9-11 of Low Band Dxing (3rd), "for a wire ON the ground, the physical length for 1/4 wave resonance will be approximately .14 wavelength". Can the shortening eff
Welcome to the wonderful world of TICed off owners... The ten turn potientiometer is probably jammed/stripped/broken/shorted/open (most likely has gone open on one side of the wiper) - however it cou
