Red did a nice job building, then explaining, this 18 MHz crystal oscillator. I especially liked his use of Manhattan techniques, and the way he explained his effort to make the new circuit work. Too often builders expect a circuit to work right away. This often doesn’t happen, and the new circuit requires some troubleshooting. Red did this with this circuit and got it working.
Red has a nice YouTube channel: https://www.youtube.com/@RedSummitRF. It is focused on POTA, but we hope it has more and more homebrew stuff like this.
Thanks to Rogier PA1ZZ for sending me this.
