I don't know of any recommended testing procedure, but a diagram of how I believe the basic (non-DC passing) Polyphaser units are designed is available from <http://www.iceradioproducts.com/33.htm>. You may wish to ignore the marketing aspect (I.C.E. make and sell a competing product, I'll leave the evaluation of the two to someone more qualified than myself), but understand that there are two main components, a capacitor in series between the input and output, and a gas discharge tube. A short between either in/out and ground is obviously bad, but otherwise I guess all you can test that high voltage capacitor (non-DC units should not pass DC). I don't know if it is possible to test the gas discharge tube itself. -Michael, VE3TIX _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
