Here is the completed WM-2 wattmeter. It took just a few hours to build over two days of my vacation.
Things I like about it:
- High quality kit
- Easy to build
- Easy calibration
- Has internal 9V battery for field measurements
- Lowest scale is 100mW for those QRPP measurements
- Reasonable cost
Things I don’t like about it:
Well…..I can’t think of any at the moment.
