*Theoretically* (I've never done it), you should be able to tune the cavity for the 442 freq, with a 'T' on the input, then on the output, cut a 1/4- open stub. The stub should reflect a short at it's resonant freq, and the cavity will pass that freq to the short, and kill it. *Theoretically* (YMMV, Not responsible for loss, Some restrictions apply, See your dealer for details. Taxes an batteries not included...) Jim
