[K2] auto tuner capabilities

I've seen and read a great deal about feeding random lengths of wire,
usually end fed, in QRP operation. All sorts of tuners and counterpoises
are proposed and discussed. Question: is the K2 auto tuner sufficient
and effective in these types of situations? I'm thinking of building and
installing one, and I'd like to know if the tuner will take care of
"most" arrangements, or will I still need something outboard. Thanks for
any and all comments.

Yes. Our ATU algorithm was in fact pioneered on the KAT2. It has eight inductors and eight capacitors, and was designed specifically to match a wide range of random wire antennas. The hardware and firmware were refined over multiple field events.

It’s great. It matches almost anything. In the field I just hook a wire to the end of a fishing pole and throw a counterpoise on the ground. Very quick and easy. I highly recommend it.

While the Elecraft antenna tuners are excellent and wide range, don't be
surprised if you find wire lengths of antenna and counterpoise that they
will not get a match on for a given band. You may still find you have to
fine tune the lengths for them to work on all of your favorite bands, even
if you have used one of the widely recommended lengths to avoid half wave
end fed operation. Results can also be strongly affected by how the wire
is deployed. At least that has been my experience with K2/KAT2 and
KX3/KXAT3, and KX2/KXAT2. But then, that is part of being a ham -
experimenting a bit to get your best results.
