Anyone else receiving this? In AM, sounds like a low breathy note on a
flute. In sideband, sounds like a sweeping chirp - once per second. I'm
suspicious, because I can hear it about S3 during the day, so I'm
thinking local. (Perhaps my gas or electric company's remote read
digital meters?)
Most likely CODAR.
