Mystery station on 10.064MHz from 0809-0815z sending steady stream of mixed letters and numbers, majority of text was letters with few numbers.
Sent by hand key, not electronic, paused for a few moments but no replies heard, then resumes. Good 539 to 559 report and I think it's in SE Asia, probably China.
Aviation traffic noted from Indonesia on nearby 10.066MHz USB and Asian (Chinese dialect) couple chatting on 10.067MHz LSB.
Any suggestions team?
