HF Beacons / Re: Mystery Beacon 7508.75

Well, it was quite clearly SDHHDD, but now it's a D

Perhaps some sort of malfunction with the sending software occurred? Dunno, but it went on for quite a while until I got bored watching it.
I wasn't the only chap to see it, but since it seems to be back to normal, it will have to be one of those little mysteries we all live with. Twente's SDR isn't perfect, but it's good enough to get most digital modes to copy properly, providing you fiddle a bit with things.

Thanks for the read, fellas!

It would help to have at least a rough idea of your location. In some areas that signal could be a fixed point to point service such as radio teletype so it would not really be a beacon. I cannot hear it where I am in California. At the moment I can hear the Russian beacon K on 7039.3 KHz so I have pretty good reception from that direction.

Jim, I was monitoring via the online SDR at the University of Twente, which is physically located in the Netherlands. Thanks for the read, though, mate!

Not a clue. Anyone recognize this?
