Unwanted sidebands :-O..

Often I find 'unofficial stations' having problems with their sidebands, +/- 10 kHz or more (no it not giving HI-FI for the listeners on AM  ;D).
Here is a suggestion to solve the problem:
The diagram shows our old homemade AF filter, which has now been replaced by a 'SW200' audio processor and +/- 5 kHz.
