Accurate QRP SWR and Power Meter

In the quest of good SWR and Power Meter


Finally come to this solution : Compensated diode detector and OLED display.
Software optimized for accurate and fast response.



 The prototype testing was surprisingly good. It beats Daiwa CN-801 in low power region. Since the pickup was designed for low power, it can not be used for power higher than -say- 20W.

Initial Testing Setup


 Here is the circuit board for stand alone unit :



Work is still in progress. So, more stuff to be added later.
