Hi to all,

Fortunately is this not my signal, but I heard this wave issue today and also sometimes ago on the satellite AO-100 in the mode FT8.

It sounds like RTTY. I enclose the wav file.

Some weeks ago I also asked for this strange issue, but didn't get any answer yet

Please give me any ideas.

Thanks a lot , Karl OE3JAG
