Jim, Thanks for those suggestions! It never occurred to me to decouple the transformers from the AC line. In other words, disconnect the antenna from the monster. I'm told that many of these little switchers have toroids or little transformers in them that are pretty effective with noise supression, and therefore able to get Type Acceptance. However, when they are manufactured in China or Indonesia, etc., they get creative in order to save cost. They can still claim Type Acceptance. Elimination of the toroid winding or small transformer and replacement with plain wire is the answer, so now we have a noise generator. AD6ZJ deals directly with some of these devices and explained this to some of us this morning. He also mentioned that the frequency of many of these switchers has become progressively higher than before, some being up in the 3 MHz region!
I'll check out your site for suggestions. My preference would be to purchase something that the electrician can install, since putting some sort of homemade device would probably not be acceptable to the electrician or the consumer. It also is a matter of my own responsibility. I'm open to any suggestions. You may have the answer to the problem! 73, Jim W6YA ______________________________________________________________ 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
