Good lord, what a Goldburg way of doing things.

Use one transistor in a phase-shift oscillator configuration and chose
your components for the same waveform ;-)

While you may not get the same effect or knowledge of building the circuit
there are some ICs that will do that in one small package.
Even the one transisitor oscillators are good enough for learning the code.
