Hello Markus, VLF
I tried to make some accents in the spectrum = grab to=20 make U clear :-)
 
If I do time measurements in Spectrum Lab with = the mouse=20 cursor, then you went on air at ~07:42 and did go QRT at = ~13h32.
But if I move the cursor one pixel to the left = or right=20 timeline goes also up or down 10 minutes / pixel.
So, my time indication is not very = accurate (+10=20 and - 10 minutes)
 
Did you made some pictures of the setup to = give me (us)=20 a idea of the working conditions.
What was the TX ~output during your=20 test ?
