On 6814khz 0220 utc 02/17/2017  40khz wide.

Well I thought this could be OTHR but it appears to be 40 Khz wide and it tends to move frequency of a few KHZ upward.  The sound file is here:


And of course the picture file is attached. Any ideas from where this signal comes from or what it is?

tnx vgw

Yes, it is an OTHR.  Exactly which OTHR I cannot say, it is not any of the normal suspects or if it is it is a less used mode.

(edit)  Based on  the time and signal strength this radar was heard in MD this morning I would say there is a good probability this is the US ROTHR in VA, although based on my receptions here this is not a typical operating mode for that radar.
