Anyone else receiving this? In AM, sounds like a low breathy note on a

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?)

If it is codar, you can put the radio on sideband and move the VFO
around. The sweep is wider than your typical sideband filter.

The codar frequencies show up in the FCC database.

CODAR are experimental licenses so on-line you have to look for those at
fcc.gov.
(Your meter readers use 900 MHz.)
