Hi,
I am collecting circuits of simple keyers of all types. There were a lot of these around before people started using PICs for keyers and a lot of these designs were pretty clever and interesting. Some used relays and did not have exactly 2:1 dash/dot rate ratios but really minimized parts count. Anybody know of a source of schematics on this subject? I'd trade files with anyone who is interested.
Thanks and 73,
