Nice links from both of you guys there - i've got both saved. I'm going to try and see if radar images are possible to correlate with visual observations as they happen - i'll keep you all infromed with what I find...

I collected several data since years from OSWIN (it is only approx 20 km away from home!). I’m sorry that I have not done a translation yet. But maybe you’ll understand the table – or much better would be:
Who likes to translate it so that I can put an English version online?
To say all only in a few words in English is a big job for me…
Only this - very very short: There seems to be a connection for the first part of the night (~evening hours) if there are -LATE- OSWIN echoes, the best is up to 19 UTC or longer. After approx that time echoes will end due to changings "with electrons in the atmosphere" (very simple said ...).
But - it is a pity - I think OSWIN is too far away for Great Britain. Approx Netherlands to the West and Poland to the East and Austria / Italy to the South can get a helping hand by watching OSWIN.
ALWIN is too much north for me but it will show the changings in mesosphere at seasons begin + end!

“In DBS-mode it is possible to swing the antenna beam in three zenith angles (7°, 13°, 20°) in the four directions North, South, East, and West. Such steering is made by a phase delayed feeding of the six antenna rows or columns in transmission case and in case of reception by a software supported post-beam steering (PBS).”
