[TowerTalk] c31xr

[Frank C. Travanty]

I had a similar problem with my C31. It was corrected by first insuring
that all the element lengths were per the lengths in the manual (I had
made some adjustments to the 15/20 drivers), then spreading the stock 20M
hairpin coil slightly for ~ 3/8 inch spacing on the windings, and finally
adjusting the spacing of the original lengths of parallel feed wires at ~
0.7 inches.
