Re: help with signal ID (pic and audio included)

 

I have seen this signal as well and haven't been able to identify it. All I can gather is that it's 8 distinct tones in 500Hz bandwidth with a very low symbol rate. Other than that, I have been stumped.?

It appears to be a harmonic of a Very Overdriven FT8 (12 seconds) signal

I have heard that signal before. I am guessing it's one of the wsjtx modes/sub modes with a 15 sec sequence (12 sec transmit), but haven't heard it on long enough to cycle through them. It is not FT8 or FT4.
