The K2 "APPLICATION NOTE: RF Detector Accuracy", says "...We used a 100 = MHz scope to make sure that reference power measurements into the dummy = load were accurate..." I have a 100 MHz 'scope (Tektronix 465, Ebay, about $60). How is QRPp = measured using a scope and a dummy load (Old Heathkit Cantenna - anyone = need any Castor Oil? I have a gallon<g>).
