This is an interesting one. Using the AFE822x with 43' ALA100LN E-W loop. A couple of notables- Hawaii came in for s decent showing, hardly surprising since antenna is E-W, 9 decodes for Panama, for the same reason as Hawaii. I will expect to see far less of Panama on this antenna. And then there was Russia. I think? The whole set was also done with 0.5 kHz spacing.
Russia looks tempting. Times are reasonable for it, but also have three other stations on the same frequency - Wiarton, Sandy Hook, and Upolu Point. Upolu Pt is 100 baud, the other two are 200 baud, and the loggings for Russia is for 200.

Tough call with Semikarakorsk. You got a lot of decodes, both spread out over time (with a lot when propagation suggests it is not possible) but also clustered in bunches.

Very tough.
Forgot to put a bunch of useful info in my original post:
Semikarakorsk is UTC+3, sunrise at 0635 local time (0335 UTC) and sunset at 0617 local time (0317 UTC). (Times for Mar 12, not Mar 10/11, but its close enough).
Taking that into account, it is reasonable that it could've been in here for at least part of the time, I'd say up until 03:41:19. After that it would seem to be too much sun over there. But then.... I don't know. With 3 other stations on the same frequency over here, I'd say they're all bad decodes disguised as Russia.
We'll put this set of decodes firmly in the category of maybe.
