simple keyer circuits
« on: February 21, 2006, 07:46:28 PM »

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,
