This is a perfectly fine way to provide CW capablity. Many HSMS 
operators use this method as most radios have problems being keyed 
above relatively low speeds, at least without modification.

Most designs that I saw used a continuously running phase-shift 
oscillator to provide a sine wave, and then keyed it with a transistor. 
This ensured chirp-less, harmonically clean signals.

Just a thought.
