Jim,

Check here for an alternative TE solution sans the antenna part.

Also consider, if all else fails, purchasing a Westerboer vario that
has electronic total energy. They work well and there is at least one
older VW920 for sale on Wings and Wheels. These also give you speed to
fly and final glide info. Used, they are a great deal.
