Here is the capture:

The event was after our local sunset and you can see the background
noise was starting to pick up, as it usually does at that time of
day.  Ossi stayed in there pretty much throughout the evening. 
The good SNR could be because night-time noise level hadn't established
themselves yet.

Here is a much later capture with three European signals: "5"
"NM" "PA0A"

LF conditions seem to be improving.
