Greg - Use google.com -- tons of CPO's there http://www.google.com/

For example -- see URL:
http://www.uoguelph.ca/~antoon/circ/morse1.htm

And you can use a door buzzer in lieu of a CPO -- but buzz instead of nice
tones.

AND You can also downlad morse programs -- some allow sending on your
computer. URL:

MFJ has one at URL:

om...
I am attempting to make a code key practice unit. I cannot find
anything out there! I am going to make a simple tone generator so I
can practice. Is this feasible? Are there any other designs out
there besides making a full oscillator?

Thank you
