Away back in 1930, two radio amateurs, C. M. Chorpening, W8WR (now
W8MJM), and F. H. Woodworth, W8AHW, both of Youngstown Ohio, began searching for
a better microphone for their phone transmitters. Up until this time they had
been using various carbon type microphones. The condenser type appealed to them
as an answer to their problem. Several units were designed and given trials on
the air. Before long, other amateurs among their aquaintance began visiting
their shacks, interested in either building or buying this new type of "mike."
Chorpening and Woodworth, encouraged by this interest, decided to form a
partnership and build these units for their friends. While the condenser unit
proved reasonably statisfactory, it had certain limitations which it was hoped
could eventually be overcome.
