Ed, With the Elecraft DL1, just use the DMM probes. If you do not have the DL1, connect the RF Probe across the dummy load (use a Tee adapter if you do not have direct access to the dummy load terminals) - but keep the power to 5 watts or less to keep from zapping the diode in the RF probe.
You can also use an oscilloscope (with a 10X probe) to measure the peak to peak RF voltage across the dummy load. In that case, the calculation formula is Power = (Vp-p) squared and divided by 400. Derivation left to the student. 73, Don W3FPR On 8/13/2011 7:53 PM, EMD wrote: > Thanks Don, > > I will give that a try.
