Radio amateur sending a modem code I do not know but it sounds really nice.
Recorded from the website of the Twente university in the Netherlands using the built in recorder.

Nice one. Sounds like one of the domino-ex modes, 8 or 16 I'm not sure. Now that they use output from PC soundcards they've come up with all kinds of crazy digital modes for different propagation circumstances.
