John, I think that was the element from the QST project you mentioned. I didn't pay a lot of attention to it at the time. Then I read something on the AM Phone site that said this element is flat from 30 to 15000 HZ, and produces amazingly good audio. There's another microphone project in April QST that used an element removed from an old camcorder, so I figured this one could be substituted. Mike Duke, K5XU American Council of Blind Radio Amateurs
