    It means that whatever you meant to post isn't appearing - at least for me

    This is obviously the harmonic output of some sort of switch mode power supply. Any sort of modern home electronics may be causing this. It is nearly impossible to identify the culprit from listening to it or looking at a spectrum display. You will need to get out of your armchair and hunt it down. Think TV's, Computers, Wifi routers, washing machines etc, not international jammers! [ADDING: "Wall warts"]

    Start by checking your house. After that, get a portable radio and check your neighborhood.

    We answer these same questions multiple times a week here on the Zed. Look through the posts.

    Ok got it. This is the first time I have ever seen it in the last few months so someone was probably running something. Thanks for the answer!
