In the latest Issue of the on line publication AntennaX in the Monthly Column "Stones Throw" publisher Jack Stone describes the construction of a very simple low cost Accurate 1 or 10 watt range RF Power Meter and Dummy Load. Jack explains how to calibrate the power meter using a DC power supply and Digital Voltmeter.

This novice level construction project is ideal for a WSPR station, and with the addition of several more connectors it could be used as an inline power meter.
