I always see the VFO-B cursor on my P3. VFO-A is green, VFO-B is magenta,

A bit of 'trivia' first:
That was supposed to be a solution in the KAT500 tuner. The initial
design put the balun on the input of the tuner, and attempted to float
the rest of the tuner while trying to maintain balance.
There were problems with maintaining balance through the rest of
Great; thank you for the trivia, very helpful. I figured it had already

The BL2 on the output of the tuner may not be the total answer. The

some study into antennas and transmission lines before assuming that

Eric,
A V beam will be quite directional (bidirectional) and the response
depends on frequency. especially at those frequencies where the length
is in excess of 1 wavelength.
You must have found a good length if it operates well with the BL2 and
the KAT3 combination.

Maybe not. The analysis presented in this article:

balanced tuner designs (and good balance in the load). The stress

Yes the reason for the length of 285 Ft is based
on reading Cebick's musings in antennix on long wire anenna's / V beams

wavelength produce slightly more gain than multiples of 1/2
Bob,
My analysis - while floating the unbalanced tuner may be possible in
theory, in practice, it is not practical. There are always be points
that will be found to upset the balance.
There is a reason for creating balanced networks, and putting the balun
