Byron,

We are getting close - FAR Circuits sells the CMOS pc boards for a
capacitance touch keyer (using scrap pc board material) that was in
the May 91 73 magazine called the Copperhead. That pc board along
with a curtis chip, CMOS Super Keyer, board (or a qrp-l designed all-in-one board) may
make for a real nice, lightweight, rugged on-the-road keyer.

I am bringing my "factory kit" Copperhead to Dayton for the
hospitality suite show-and-tell (the kit is not available anymore
from what I can tell - precut wood, paddles etc).
