I used a 1N416E diode and a 1500pf filter capacitor. The tuning cap doesn't have any affect. Should this circuit work? If so what could I be doing wrong? Mike Hmmmm, I am not suprised at you 0V out near the Wireless Router, when compared with a Microwave Oven, the difference in Power Output IS significant. (100Mw Spread Spectrum, 100+ Watts CW) Hi You It seems reasonable to assume the oven door was closed when the voltmeter readings were made. But, If-*IF* the meter readings were accurate *and* he was able to read even 1 mv at the Router and 80mv at the oven, there is alot-*alot* of error introduced into this test from somewhere. The math and power level estimates are left for the readers to deal with. Jerry |
