Peter, I had problems with "drift" on my SG-230
despite all the radials and grounding and such,
and found the only way I could use it on 160
was to build a "smart lock" circuit. Initially
it would match fine, then would "hunt" after
I transmitted for a while - the Smart Lock
keeps it from tuning once you have found a
good match. The sgcworld.com website has
a schematic in case you want to build one,
it is quite simple.

I recently picked up a SGC 230 smart tuner and have installed it at the base
of my inverted L. The 230 has proven to be just as versatile as all the
comments I read had indicated it would be. I am really do want to
push up my 160m
tally later in the year but I also want to (need to) retain the one wire
antenna to work on 30m/17m/12m
The only band which I have difficulty tuning is 160m, observing the SWR/Fwd
meter on my Corsair II suggests that the tuner is constantly hunting looking
for a good match.
I plan to upgrade my inv L in terms of vertical height and ground/radials
during the summer months and would welcome any feedback, suggestions, ideas,
balun arrangements, radial attachments or experiences using the 230,
thanks and 73, cu on warc bands or 160
