You were putting in a good signal here today at 13.25 and I don't recall hearing you before, so it is most likely better. My receive Antenna is a G3LNP loop in the North/south plane. I have just put

Hi Dave, I've been reading your Home Page and came across a formula for the radiation resistance of a loop antenna: Rrad = 320*Pi^4*A^2/L^4 where A is the area of the loop in square metres and L is t
