This short article describes some experiences I had when trying to cure the very bad pager interference I had.  Examples of this interference can be seen on my pictures.  I've split the article down into four sections to make it a little easier to read online.

If you have problems with computer-related interference appearing on your picture you may want to look at this note on reducing computer interference If you are uncertain what type of interference you have, this article "Interference to APT/WEFAX Weather Satellite Reception" by Alan Sewards may help.
