Noise measurements Koos
Koos Fockens, PA0KDF, has performed multiple man-made noise measurements on different locations in the Netherlands, also in Maasbree. See the link on the right part of this page. The results in Maasbree indicated a 'rural' noise level for an antenna location further away from nearby houses.
We did also some measurements ourselves, and they were close to the results of Koos.
