Re: [IRCA] phased BoG experiment in Masset.



Neil, I suspect that that was the case with my experiment.  With the
shorter wire, and unamplified, no wonder the signal was too different in
strengths to get it to work properly.  This will be a good spring/summer
experiment when I won't need to erect the N Beverage at all, freeing up
another amplifier.  Do you feel there's any difference in the width between
// BoGs?   Also, would a stagger work any different than // wires with the
shorter one being between the start/end of the longer wire?   73,  Walt
