Oak Hills Research WM-2 QRP Wattmeter – Part 5

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:

  1. High quality kit
  2. Easy to build
  3. Rugged
  4. Easy calibration
  5. Has internal 9V battery for field measurements
  6. Lowest scale is 100mW for those QRPP measurements
  7. Accurate
  8. Reasonable cost

Things I don’t like about it:

Well…..I can’t think of any at the moment.
