Thank-you; it has been an interesting learning exercise for me. For the detector, I actually used a little gadget box circuit that my Dad had made up years ago. When I first found it (unlabeled) in his electronics stuff, I didn't know quite what it was. Like so many other little boxes he had, he used to toss a handfull of components into a small box and use it when he was testing something out. When I was young, they always seemed like magic and mystery. It was only after several years at college that I could even start to figure out the mysterious little circuits inside.
The particular setup I used was much like N5ESE's QRP Dummy Load with it's built-in RF Detector (http://www.io.com/~n5fc/dummy3.htm); but in my case, I used a standard "T" connector to combine my Dad's detector and a separate 50 ohm dummy load (also in a gadget box). I stumbled on N5ESE's version when I was trying to convince myself of what my Dad's actually did; especially since Dad's was wired a bit different from the others that I had seen. At Gary Schafer's (K4FMX) recommendation, I also put a 6db pad between the sweep/marker generator and the cavity's input. If you like, I can sketch out the whole test setup; just let me know with an off-group message ([EMAIL PROTECTED]). Enjoy. <<< vern >>>
