Hi Gang
*The electronic TE vario should be possible to implement with modern
electronics today. I have googled this item but have not been able to
find one. Maybe it doesn't exist for whatever reasons. It would sure
simplify some of the complex TE probe systems that stick out of the
empennages of many gliders. Any ideas or thoughts?

I don't think Dave is asking about the 302 since it uses a TE probe.
What I think he's asking about is doing the TE calculation in real-
time in silicon using just the airspeed and altitude data from pitot
and static ports. *AFAIK, no variometer has ever taken this approach.

I've wondered about this too since it would do away with almost all
the special variometer plumbing as well as the probe. *It would also
eliminate a lot of pneumatic artifacts.

The 302 does not require a TE probe. You can connect the static port
to both the static and TE connections on the 302 and use pure
electronic TE compensation. The 302 was designed to do this very thing
as specified in the documentation.
