I am talking about a tuner in between the XV-50 and a rather depressing little
end-fed dipole antenna!

Subject: RE: [Elecraft] General Trasverter Operation Question
Why would you need a tuner between the K2 and the XV-50? The XV-50 has
an
input attenuator that provides a good 50 ohm load, and the K2 should
drive
it just fine with only a piece of coax connected between the K2 and
XV-50 -
the SWR on that coax line should be very close to 1:1.
