Michael, K8CN, thank you for the link. Now I can identify some of the OTHR
I routinely receive here in N. Colorado.
So my horizontal lines - the second image - may be CODAR. The first sure
looks like the Iranian OTHR. I also receive quite a few of the CHN
Widebans OTHR. Of course, all this varies based on solar activity and type
and the state of the ionosphere.
