Topband: RFI sources on lowbands

[ON4WW_pandora]

Hi,

At the start of every lowband season after installing the beverages in 
October, it has become a ritual for me to turn on the receiver in AM mode 
and switch the 8 beverages to find out in what heading(s) I got a new type 
of RFI that came up.

Over the years I had many such RFI cases showing up. As I made recordings of 
quite some of them, I played with the idea of putting them on a webpage.

I finally got to it, here goes: http://www.on4ww.be/emi-rfi.html

I made a more or less detailed story on each of these cases, describing how 
I went about to find these RFI sources, and how a solution was found to 
continue lowbanding RFI-free. Hoping this may give some insight at what is 
around, and what can be done.

Merry Christmas all ! And a RFI-free 2011 topband season...
