136kHz E-field probe found

With a fresh battery, I think this will still work. It was re-found yesterday. 

If it does, it means I can do some local tests with my beacon into the earth-electrode "antenna" in the ground. I already have a local RX test site in mind.

UPDATE 1540z:  A short range test in the house shows the EFP still works.
