It is mechanical, has two ports on the back, one says static, other
capacity. *Emblem on front has a A W written on it. *I know it's more
complicated than just plugging in the static line and the capacity
line.

but it is.....that simple.. the "W" in the face is "Winter"
..if you want to use it as a basic mechanical variometer as it was
intended....connect to static or TE (TE is simply a "compensated" Static and
connect the other side to the proper size capacity bottle.....keeping in
mind that especially these very odd range variometers can and usually do use
a .90liter, or even 1.8 liter capacity bottle and not the normal .45 used on
almost every other variometer.
also remember that if this is a very old variometer just becuase the needle
appears to move in the correct direction doesn't mean it's any where close
to be accuarte anymore, most of these older instruments really need to be
overhauled even when kept in reasonibly good storage after 15-20 years old.
I see these all the time that are closer to 40 years old and the needles
move..but far from the way they were intended.

Hey, speaking of overhauling mechanical varios,
I have a Sage vario that's about 10 years old in my plane.
The plane has always lived in its trailer out at the airport (at least
since it got this vario). How out-of-whack is my Sage going to
be after that amount of time in the plane? I have to admit, I
barely ever look at the thing. I've trained myself to avoid looking
at the varios -- maybe once per scan to compare the 20s avg
with the achieved climb rate displayed on my pda. When my
LX vario went haywire on a flight last year I could barely cope.

Also, speaking of the LX160, would any of you LX people have the
chip on hand to upgrade it to v2.12? The last time I looked the
shipping charge from Slovenia was more than the chip cost!
