OSK and FSK

I got OOK and FSK working together (the S shape in the middle). I'm also now using a crude oven, but am not sure yet how stable frequency is over long time spans.

I kept thinking my oscillator was drifting frequency because the line wasn't straight. Turns out it was my curved monitors!
