Pretty cool  field phone!   had never seen a '
implementation of this  Thanks ! Hue!

We had a similar experimental system we built from scratch when in Jr High
that worked in this manner. I was actually amazing how  far it would go. Of
course the more sensitive the ear phone the better.....

Thanks Ed Sharpe archivist for SMECC
