[Elecraft] K2/100 + KAT100 + Cushcradt R8 Vertical

[T. David Yarnes]

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.
