[Elecraft] Tuner Options

[R Thompson]

Hi John,

    I was looking for a tuner that could be adapted for use at the
antenna end.  Recently I purchased an LDG Z-11ProII, but I haven't tried
it yet.  There is information on the LDG website on a modification to
install an internal battery pack for remote use.  After it arrived I
opened it up to see how a battery pack might be installed.  At the same
time I looked over the front pushbutton PC board and I think that by
using opto-isolators it may be possible to run a multi-conductor cable
to a remote control panel.  It would be nice to have a remote panel and
be able to manually tune it while on receive.

    It will be a while before I attempt this, maybe after the warranty
has expired :-)

I bought an Orion and its ATU which had similar problems as above. I moved the shack so that the end of the dipole points directly to it.  I also had a MFJ 929C it was a bit of a pain to tune but it did work.  I now have a MFJ 933B and I think it is a great.

It remembers previous tuning but does need the odd operation of the Tune button occaisonally to improve down to 1 : 1.    It doesn't like slow CW at the higher power level (300w) though.
