The sigs where chopped by QRN, SpecLab gave a trace but WSPR didn't decode assume he didn't get the sequence correctly. I'm using a TS440 which can't switch off the AGC by nature. So reduced the gain and turned up the LF gain to get a proper feed for the WSPR decoder. At the moment there is a small trace visible. About Paul-Henrik location, I associated Finland as relatively low noise area. But assume that the delta loop is doing a fine job. Tonite there is less QRN will give another run.
