[Boatanchors] Learning Code during WW II

Wed, 8 Jan 2003 04:50:32 -0600

Hi Bill & Gang,

T.L. McElroy was the world's fastest code copier back way before WW2, way
before the advent
of the "electronic keyers" so, the keyers you mention are undoubtly machines
that sent code for
practice, either from tape or other medium....

After the Vibroplex patent ran out, there were many copies put out by
various manufacturers and one
was the "T.L. McElroy" model. A "bug" is a "Semi-automatic Telegraph
Key"....
