On Dec. 2, 2011 at about 0522Z I stumbled across a CW station on 8112 kHz. It was very weak, in and out of the noise, mostly just below the noise level. When I first heard it I thought it was sending "W W W W W ..." but then it seemed to go into a plain text message of some sort. I only heard bits and pieces of it. It seemed to disappear at around 0530Z.
I do not think it was the M10 numbers station. It was not sending number or letter groups.
Has anyone else heard this and have more info on it?
