SDR Transceiver

10 KHz - 220 MHz Variable Frequency Oscillator

This is a VFO (variable frequency oscillator) project that can be used for homemade devices such as superheterodyne receivers, DCR transceivers, SDR transceivers or QRP ham transceivers. it also has histogram indicators for signal strength (s-meter) and 20 band presets and can also be used as a radio frequency/clock generator.

SDR QRP HF Transceiver

Has a bar graph indicator for signal strength (S Meter) and 20 Band presets, and can also be used as an RF or clock generator.

Working range is 10 kHz to 220 MHz, can be used with for Pro Mini. Use general 128 x 64 I2C for for display and Si5351 module.

Support I2C data transmission, only need 2 wires to connect the display or Si5351.


  • The bar graph of the signal meter through the analogs input (ADC). It can be used as a local oscillator on Homebrew radio receivers (such as superheterodyne, SDR, direct conversion and Homebrew QRP transceivers), a simple RF / clock generator for calibration reference or clock generation, a common 128 x 64 I2C OLED SSD1306 display and Si5351 module.

  • I2C data transmission, only need 2 lines it can be connected to the display, with high stability and accuracy of frequency generation.
