"W5DXP" wrote in message ... How about looking at the voltage across the resistor? i.e. the difference between the voltages at each end of the resistor? -- 73, Cecil http://www.qsl.net/w5dxp That is what I mean, By looking at both ends at the same time with a dual trace scope. I guess I could also go A - B. I have the stuff to do it with. About 60 feet of 9913 that I can short the far end on, a dual trace 100 MHz scope, and MFJ analizer as a signal source. The latter is also usefol for finding exact 1/4 wavelength frequency, as I can't measure the coax length. ( Goes through several walls). Tam/WB2TT |
