That's VERY surprising unless you're using high Z feedline (window line
or open wire).
, but I cannot get it to match the 80 meter dipole cut for 3800 down to the CW
area. What am I doing wrong?
It's probably nothing more than a learning curve for how to find a match
with this tuner. When I was first learning my Ten Tec tuner, I found the
method described in the manual to work pretty well. The impedance
presented by the antenna to the tuner will be strongly dependent on
feedline length, and could require a setting two or three clicks on
either side of the zero center position.
