README.me 

This project is reengineered out of the TenaTester build by ZL1CVD.
The firmware is completely written by myself, the wheatstone bridge was mostly drawn as seen in the TenaTesta demo videos by ZL1CVD on youtube. The electrical component values were modified by myself to fit my personal requirements. The si5351 prt in the schematics was replaced by an adafruit breakout board.
