Oh, that's easy. You're *trying* to build an oscillator; give up on
that goal and choose an easier one: try to build an amplifier. I mean,
really *want* to build a stable amplifier. Voila! An oscillator!!

I once built a power supply that oscillated above 150 MHz.
Unfortunately, I could never drop it into the 2-meter band.


Heh. Of course a DC power supply is indistinguishable for
a 0Hz oscillator under the best of circumstances, right?

But, 150MHz. That's pretty special. What were you using
for a pass element(s) ?
