QRM on 40 meters

I know that I have seen this signal on 40 meters before but I can not remember what it was. It seems to be very wide for the CW/Digital portion of the band. What is it?

    May be interference from your air conditioners controller . I get a similar pattern whenever my ac runs. Also see it on 20m.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
