Sorry folks, due to congestive heart failure, I am having a very slow recovery from a bad case of the flu, and a foggy head to boot:
A .01 uF capacitor across the hot and neutral sides of your power strips for 2 wire AC distribition systems should be good for all RFI frequencies. Since Xc = 1/(6.28 x f x C) , as f increases, Xc will decrease. If Xc is 2.5 Ohms at 7 Mhz, it will be 1.25 Ohms at 14 Mhz, and .625 Ohms at 28 Mhz, etc. Judging by the mail I received on this post, I should have added this: For each AC receptacle on your your power strip, the short straight slit is "Hot", the long straight slit is "Neutral", and the round or sometimes half-round socket (forming the top of a triangle) is the "Ground" - this the socket that you connect the banana plug to on the wire going going to station ground. P.S. On all new quipment you buy, check to make sure that ground side of the AC plug is actually connected to chassis ground using a DVM. I bought an Astron 50A Power Supply few years back. A DVM check of the resistance from the ground side of the AC plug to chassis ground showed an open. Problem was a thick coat of paint preventing the lock washer on termianl lug connectrion from making good contact to the metal chassis. The wire to this terminal lug was connected to the ground side of the AC line in. A "floating" or ungrounded equipment chassis acts like an antenna to RF.
