An article in Electronics Now describes a using a sonar transducer as a
rotating element in a sonar system, driven by a stepper motor. It describes
the operation of the basic sonar system plus how to build the commutator for
the transducer.

If you would like a copy of the article please send a business sized self-
addressed stamped envelope to me.
