Hi Phil and All,
I have used an R7 for many years, and it has performed very
well. I was always able to load it effectively on 40 meters
across the band, even though I had it set for the CW
portion. Other bands are not a problem at all. The K2 ATU
does a very nice job. I did have some problem on the higher
end of 40 meters using the ATU in the FT-1000 MP Mark V.
Just recently I also added an R8 here, and I am currently
using it with the K3. If anything, the R8 seemed a little
easier to load on 40, even with other rigs. The K3's ATU
has no problem loading the R8. I assume the ATU in the K3
is reasonably similar to the K2's ATU. I haven't actually
tried using the K2 on the R8 yet, but I doubt there would be
a problem. 40 meters would be your only possible problem
band, and if you want to be a little extra cautious you
might consider setting it for the middle of the band--around
7150 khz or so. I think that would probably be something I
should do as well, just to make life easier.

Subject: [Elecraft] K2/100 + KAT100 + Cushcradt R8 Vertical
I am contemplating replacing my B&W Wideband Folded
Dipole with
a Cushcraft R8, the successor to the R7, as my "main" HF
antenna. The B&W is best described as a resistor with
wires -
about 10% efficient although it does cover all amateur
bands
from 160m to above 10m equally badly. I will have to
retain it
for operation on 80m and 160m, though.
What I am curious about is whether the KAT100 can
compensate
for the limited bandwidth of the R8 on the lower bands,
and how
well the R8 holds up in windstorms (we don't get much ice
here). I expect to be feeding the antenna through about
50
feet of good quality 50-ohm cable.
Real world experience appreciated.
