    Anyway, back to the question from LSJuan. From memory I got a "U" build kit - frequency generator - from an electronics shop (Altronics in Australia), and built it. USD$50. A microprocessor controller like a Teensy can also do it, "just" takes some C programming. And circuit design to drive the FF pin.

    Trust that makes sense.
    Interesting doesn’t sound to complicated! Is there a write up on how to build this generator? I don’t have any experience on circuit boards and what not.

    Did you use a knob to adjust frequency on the fly? Like a dsp5 Switch?
