QRM on 80m

So over the past few months, perhaps four months, I have noticed what can only be described as some wide band QRM on the bottom two thirds of 80m and some smaller stripes of QRM near the top end.

In this image you can see the noise, it is roughly an S point or so, but quite wide band with no real strong centre frequency.

Direction finding it will be extremely difficult if not impossible due to its ‘spread’ out nature and lack of strong signal to ‘home’ in on.

The horizontal green lines in the top section of the image are at S5, S6 and S7. Anyway, this is more of a record of the QRM to see how it changes over the coming months.
