[CW] Autek Research MK1 Schematic info needed

Fri, 18 Jul 2003 20:34:58 -0400

The Autek keyer was a patented device and it wasn't until the patent expired
that keyers started to be make by others other than the W9TO keyer by
Hallicrafters.

No schematic was ever released.

12 VDC on the jack would work - I'd guess a 300 to 500 ma cube would work
well.
