Easy solution - switch off electronic compensation and reconnect
LX5000 to be parallel to TE Winter.
I had this solution on my previous plane and it worked well.
Electronic compensation on older computers generally does not function
as well as good old TE probe,
it is very dependant on characteristics of static ports used for it.
If you are aware about cross-talks between LX and Winter, then move T-
link as far as possible away from instruments,
usually under seat vessel, but mostly it is not necessary (tested with
Winter system containing 0.9 l flask).
