7MHz Crystal Oscillator Design
After constructing a 40m wire dipole that works with my SDR setup, I needed to start working on a transmission system. At the…
2m AM Exciter
Here’s a project that I’ve been working on for a class recently. This is a very basic 2m AM Transmitter that operates from…

a practice in designing an oscillator. this particular circuit employs a 2N2222A transistor on 6 volts. i used this Electronic-Tutorials.ws page to design…
Square-wave Oscillator Meets PT2399…
Square-wave Oscillator with PT2399… from abram on Vimeo. Very short video of the waveform captured using Xoscpe of the PT2399 applied to the…
LM386 Square-wave Oscillator
Here’s a small LM386-based square-wave oscillator built from the following schematic. I replaced the 30k resistor with a 50k Potentiometer from my stash…
