   Hello Dick
    I've noted the great difference between the values reported by Mesny and those appearing in the graph you have sent. I think the difference may be explained as follows: the graph refers to two wires, where the magnetic field is rarefied only in the sides facing each other. In the case of a single layer coil, except the first and the last turn, the magnetic field is rarefied in both sides of each wire, so reducing further on the useful area and consequently increasing the  RF resistance. Any comment welcome  73  Cesare

You could well be right. But I don't feel qualified to judge.
