This is a nice, easy, useful project. It allows both HF (<30) mHz) and VHF (144 mHz) use without disconnecting feedlines. There are 2 inputs and 2 outputs (1 for each band). The dual scale meter is calibrated for 200 or 20 watt scales. An easy mod for the QRP'er is to recalibrate the 20 watt scale for 5 watts. This meter also is selectable for Forward or Reverse power, or, at the flip of a switch, the Standing Wave Ratio (SWR). This watt meter, unlike most, uses power either in the form of a nine volt battery, or by a 9-14 v power adapter (not included)
