I tried numerous circuits and numerous types (Hartley, Colpitts etc) I
had found but I couldn't get any of them to start up. 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. --Myron. -- Five boxes preserve our freedoms: soap, ballot, witness, jury, and cartridge PhD EE (retired). "Barbershop" tenor. CDL(PTX).
