The LightBlue line is the averaged signal from the Noise

 

Not complete due to computer restart after a windows update

From this measurement on I started using an RBW of 0,5 Hz You can see the noise floor drops by 6 dB

Thunderstorms over centre part of Netherlands, beacon was not shut off

Due to a mistake I unfortunatly deleted the data from 18-4 to 19-4-2018,
lesson learned, Hi

Thunderstorm over France, lots of QRN in the evening

Beacon switched off on 22-4 between 12.45 and 17.15 UTC
Thereafter my marker was not exact on the beacon so measurements are about 6 dB too low for the beacon after 17.15
Also thunderstorms over NL

Needed some corrections due to frequency drift of 0,5 Hz (in my receiver)
Effects are small in this graph
Corrections were performed at 16.51 UTC and between 21.44 and 22.04 UTC

short hickup in receiver between 11.15 and 12.00 UTC

Heavy thunderstorms over Belgium, Netherlands and Germany
Beacon switched off between 00.00 and 06.30 UTC
Lots of static noise

For the results of the measurement from may 2018 look at:
