Strong carrier (-85 dBm at my location currently); about 3Hz wide; might be LSB?. Has been on since at least 1434 UTC 10 Jan. TDoA during the day (~2000 UTC) suggests possibly two transmitters...one east coast, one midwest. (https://i.imgur.com/sJ3hcxc.png)

Appears to be some modulation? See the tick marks:

Active, on and off here at 1725 UTC on Jan 11. Some pulsing/fluttering was noted on one of the "key downs" and then the signal was stronger. Almost like maybe an antenna tuner of some kind was quickly trying to match an antenna. Very strong here, S9+15.

Copied here too @ 1910Z, S5/8.
