	And the first of my 20 questions is: Why don'y designers add 
MOVs, capacitors and chokes in their power supplies? Why are we 
supposed to buy add on boxes for every digital box? If they all 
need one, I would assume they should all have them built in. Why 
don't we start demanding they add the extra dollars worth pf 
components.

	I seem to recall many, many moons ago designing power supplies. 
In those days, we put filtering in the PSU. Yup we even had a 
grunge generator for testing the designs. But in those days a 
design to be proud of worked on any line and didn't radiate 
garbage either. It must have been a long time ago.

	Other questions I have concern radiation in and out of 
electronic boxes - another matter cheaply fixed with good design 
and common sense.

Yours in despair
