Still Looking for CK722 Heath Project

[Jack Ward]

Hello to the list again,


The CK722 germanium transistor website continues to grow.  One of the latest
additions is an interview/photos of the 1959 construction article by Marland
Olds  (W5LAN) originally appearing in the May 1959 QST.  Marland no longer
has that keyer, but remembers it well and provides a detailed description of
how and why he built it.

Check out this great project, and others, at:

http://www.geocities.com/~ck722transistor/

(Look in the "Highlights" section or the "Construction" section.)

I'm really trying to find some Heathkit project that used a CK722.  Does
anyone have such?

Also, I'd very much appreciate the chance to document any similar projects
that those on this list have built or used over the past 40 years, using
CK722 transistors.  Just let me know.

Regards,
Jack W
