What is it?

The AVR DUMMY WATT METER consists of a 50 ohm dummy load , an R.F probe and an AVR AtMega328P with a 16 x2 lcd to read the produced rf voltage and convert it to a power level. This forms the power watt meter to read up to 250watt for short bursts of course ! as the dummy load is not oil cooled. The meter features a menu system where one can set various parameters such as the resistor ratio, do a calibration . set dummy load resistance , do a save to memory , and restore to defaults and change the brightness of the lcd.

Why did you make it?

I am always building radio equipment and needed an R.F Meter to be handy.

What makes it special?
