This is a test of my new project, a VFO for use in homebrew equipement such as Direct Conversion and Superheterodyne Receivers or Ham Transmitters.
3:00 - Generating 27MHz and measuring the signal.
4:30 - SSB Using the VFO on MC3361 direct conversion receiver circuit.
5:15 - CW/AM Using the VFO on MC3361 direct conversion receiver circuit.
Features:
-Operation range from 10kHz to 120MHz.
-Tuning steps of 1Hz, 10Hz, 1kHz, 5kHz, 10kHz and 1MHz.
-Intermediate Frequency (IF) offset (+ or -) adjustable.
-For use as Local Oscillator on homebrew Superheterodyne or
Direct Conversion radio receivers.
-For use as VFO for radio transmitters.
-For use as a simple RF generator.
-Works with Arduino Uno, Nano and Pro Mini.
-Uses a common 128x64 I2C OLED SSD1306 display and Si5351 module.
-I2C 2 wire data transfer.
-High stability and precision for frequency generation.
-Simple yet very efficient and free.
