Hi Laura,

The captures are from = today,=20 12/11/2013.
The time is shown on my capture as utc between 1000 & = 1200utc.

My location is England IO83qo & Henny's is = Netherlands=20 JO22md.
Quite a long way apart to be a locally generated = signal.

I=20 note that Henny's time stamp is 1 hour different, probably using local=20 time.
