Aug 7
Every time you want to work THE DX, you will find some high level noise on the band. Recently WP2B was strong enough on 6m to overcome this noise - I was lucky. Yesterday (4 August) I got fed up with this and I went out to my neighbour and try to find the source(s) of the trouble. Just to make it short: He was very cooperative and we found an USV for the computers which seems to have some oscillation in the power supply. Second source was a Philips LCD TV set putting out a broad noise. We only needed a few minutes to find this.
On 7 August the cores arrived, my neighbour istalled them himself - well done - ├ęt voila, all noise is almost gone. Very little broadband noise is still audible, when the TV set is switched on. In this view I am happy again ...
