[Elecraft] TVI and More

[Richard]

A close neighbor was hearing through her add-on computer speakers what was probably me on 20 meter SSB. She said she couldn't make out any words, but it sounded like a garbled voice. After determining that it was indeed I she was hearing, I clamped a few ferrites on the two cheap speaker cables and the problem was solved. I hadn't had any interference problems since 1955!

I think I read here on this reflector that there is some sort of filter that I can add to my transmission coax that will prevent this sort of thing. Can anyone tell me about this approach to TVI?

Oh, and my neighbor, who has an Alexa thing in every room in her house, all ganged together with WiFi, also said her Alexa was shutting off suddenly, then coming back on several seconds later. Could this Alexa-I? I wouldn't even know where to start on that one, especially since she has all that WiFi raging all through her house.

All help will be gratefully received.
