Nice copy Eddie! The SNR is stronger than in Heidelberg. It seems the UK QRN is lower than in EU at least in the summer time! Strange, it looks like Uwe's signal is drifting in your picture.

Uwe, i've not identified the message so far. Was the transmission interrupted by rain and some accidents?

Hi Uwe

Your signal was not as strong as last night in IO92ng - 720km. Attached is my capture in 47uhz B/W. Ossi has some frequency drift so does not appear at this resolution.
I have no explanation for my apparent frequency variation apparent in this GQD locked SpecLab display.
