[Elecraft] [KX3] OT: NVIS with KX3

[David Cutter]

I've heard it said that a wire on the ground as a "reflector" improves NVIS 
coms if the ground is poor.  I can't model this, but perhaps someone could 
comment.  I'm inclined to think that it might take several wires on the 
ground to make a difference.  It's an interesting idea to play with.

Hi Johnny,

On 40 meters, I work all over the West Coast (0-1000 miles north/south) 
during the daytime with 5 to 10 W. The antenna is a random-length OCF dipole 
about 15' off the ground. I'm not sure how many clouds I'm burning, but many 
of the stations I work are short- and medium-range. I think this should work 
in your situation.
