7MHz Transmitter with AVR Soft-keyer
In my last post, I went over the design of a Colpitts crystal oscillator design that put out a moderately clean 7 MHz signal. In order to match the output

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 heart of virtually any RF system lies
Arduino: LFO Generator
here’s a treat for anyone that’s into the audio side of arduino. it’s an 8-bit two-timer based LFO Generator using timer 0/2 on an ATMega328p. i’m only using timer0 for
