[Elecraft] [KX3] OT: NVIS with KX3

> I've heard it said that a wire on the ground as a "reflector" improves NVIS coms if the ground is poor.  

A single wire under the dipole doesn't do much. Less than a dB according to EZNEC. Any parasitic effect is muddled by the "reflector" being on the ground. 

It's mostly about height. About 25 ft over average ground for 40 meters is best. Some go lower for a perceived receive advantage. I've tried 12 ft and it's much worse than 25 ft. YMMV
