Description

EasyEDA project for easy and quick build HF upconverter for work with shortwave bands on SDR receivers. Project include schematic for HF upconverter and PCB. File "HF Upconverter PCB (TH): Converter (SINGLE-LAYER OPTIMIZATION)" has been developed for more convenient producing of a PCB in home conditions using toner transfer or photoresist method.

Current development progress:
