Kirby -- PLEASE post your excellent and detailed observations on the RFI reflector. One observation about the result of your application of chokes. I'm thinking particularly of the Samsung box, but the concept applies to ALL equipment. Chokes on cables leaving a noise source, or entering a victim, kill the part of the RFI that is conducted out of the set on those cables and RADIATED by those cables acting as antennas. Chokes cannot do anything about the trash that is radiated by WIRING INSIDE THE BOX. So -- the trash you heard after you applied the chokes, assuming that the chokes were ENOUGH to kill current those external wires, the remaining trash was from inside the box, and you'll never kill it without a major science project inside the box. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
