From the project
SSB HF transceiver using Phasing techniques and SM components KICAD files for receiver board initially
QRPTransceiver is an HF transceiver project using phasing techniques, surface-mount components, KiCad hardware design files, and Raspberry Pi Pico firmware for control and user interface.
- hardware design in KiCad - firmware for Raspberry Pi Pico using PlatformIO/Arduino - local oscillator control using an SI5351 - front-panel UI using a rotary encoder, push buttons, and an ILI9341 TFT display
