NVIS and Field Day, that reminds me of my very first Field Day. We had
not put up an 80 meter antenna, but I wanted to try the band in the
evening, so I cut a 1/4 wave length of coax, strung ot through the trees
at about 6 feet high, twisted the center conductor and the braid
together and stuck it into the phono plug output of my Heathkit DX-60A
transmitter. I had no counterpoise, btu I was a kid and didn't know
better. Likewise, NVIS was unheard of those days. It worked after a fashion.
Today, when I operate portable with my T-T Scout, I run a 1/4 wave wire
from the roof rack on my SUV out to a tree and I use a 1/4 wave
counterpoise connected to the rear bumper. With the Scout running 30
watts, I get S9 reports on CW and SSB when checking into the 80 meter
traffic nets back home, a distance of about 50-60 miles. The portable
location is in a wooded lake valley.
At home I use a low 80 meter dipole at about 15 feet for NVIS and it
works great.
So, yes, NVIS really works.

The Corsair should be a good FD choice.
Add the ICE bandpass filters, and add an NVIS low dipole for 80m and 40m and
you should have a good all around station.

Contrary to popular belief, skip CAN be worked on 80m NVIS dipole that is
only 6 feet off ground!
Works a lot better for FD than an 80 m dipole a half wave high. One time
we had access to windmill towers that high and put one up. We couldn't
work much at all around Iowa, but heard the coasts well, but we couldn't
get a really competitive signal to the coasts and so made few contacts.
