It is still not very clear to see in your screenshot what it is.
And I assume you are familiar with the signal from SSTV and KG-STV
So I suspect that it is an EasyPal signal. (high resoluton SSTV)
R0AU can be seen regularly in this mode around the displayed frequency in your screenshot.
Hope this wil help
Ok, I have MMSSTV installed and I have tested receiving sstv- signals.
That signal in my photo sounds like 9600b ”noise”.
I have also KG-STV installed, have to check with that.
