We are looking for any existing Form337 to install a battery driven
electrical system in an SGS 2-33A. We are tucked in close to Class B
airspace that is about to expand in the next year and feel a
transponder would be a great idea in all of our gliders. We've been
using handheld radios for years, but no one has made a handheld
transponder that I can find.

Thanks
