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.

Hello elecrafters,
It is off topic and you may wish to press 'del' button now.
Local ham clubs together with some hams in the China Mainland are going to
do some drilling in ARES within the Pearl River Delta area (with a radius
of about 50km). NVIS could be one of the operation to trial run for ARES.
My questions are:
1. Is the power output say 10w from KX3 good enough for such purpose
under SSB? We don't want CW which requires training operators. Phone mode
can be operated by anyone with minimal guidance (a simulation under
emergency).
2. During day time, is 40m a proper band to use (no 60m band in ITU Region
3)? If yes, what will be usually frequencies used such proposes?
3. I am going to use Buddipole for the NVIS antenna. Did you go good
results for similar operation in the past?
Looking forward to your advice and thanks in advance. Please reply
off-the-list so as to save the bandwidth here.
