Yes, AND groundwave weakens drastically with increasing frequency. With
average soil, a station operating on 550 kHz will be 21 dB stronger at

It is absolutely true that antennas intended for NVIS use do not have to be
hung low. But they CAN be. And there are instances where doing so can be
desirable.
When I lived in Hawaii, we used NVIS for reliable statewide HF communications
to very good effect. When I hung my dipole up about 30
I find that trying to match two beat notes when I can only hear one at a
time to be hard, best I can do is maybe 10 - 15 Hz Hz depending on the
frequency.
FWIW: The Burdick Calibration Method [BCM] for the K3 is actually much
easier to perform than has been suggested in this thread,it is

When I key the mike, my friends hear a hum on my signal that is not there when
I use the Heil Proset K2/K3. I hear the same thing when I monitor my signal on

I’ve checked the connections at both ends and do not see anything amiss. At
the mike end, the ground wire is ‘floating’ and no
Wait, why would people think verticals are good for NVIS? Isn't a
vertical's radiation pattern pretty much "sideways but not up", and NVIS'
desired radiation pattern "up but not sideways"?

There is a major myth regarding NVIS that antennas must be low. This is
totally false. The facts are that vertical antennas are terrible for
NVIS, and that horizontal antennas
Greg,
You might want to consider doing this within the Winter Field Day event.
There are 'indoor', 'outdoor' and 'home' categories. The next event is Jan
29-30, 2022. See www.winterfieldday.com for details.
I had fun operating the event in Jan 2021 from a portable beach house site
using a K3/10
This is just a suggestion and forgive me if I’m not aware of something that
already exists. What if there was the annual event called the The Elecraft
NVIS field day?
As we all know Elecraft plays well with others, and along that theme
everybody would be welcome to participate in such a field day
