Garry: Hopefully you had better capture levels around the 0430 to 0530 UTC 
time frame, Stefan's signal was in mid -40s here.  I lost that 0430~0530 UTC 
capture by closing the wrong
PC window by mistake, but here is the subsequent one. Signal was still in 
the mid -40s at the start, fading towards 0630 UTC.....
