OK .. I goofed. Can I blame it on learning all this stuff back in the
AM days? (when SSB stood for 'silly side band'.)

It still seems inherently wrong to take digitally recorded version of
a CPO output and use that in an attempt to create a CW signal. How
much distortion does the record/play back add to the signal? Was the
_original_ tone a good sine wave?

A CW transmitter is a simple thing, why make a complicated one?
