[TenTec] Power supply types

[Ken Brown <ken.d.brown@hawaiiantel.net>]

What is the probability that a transformer/rectifier/capacitor 
filter/linear regulated power supply will generate and radiate (through 
AC power input or DC power output leads) RF noise of sufficient 
amplitude to be bothersome? That probability may not be zero.
What is that probability that a switched mode regulated power supply 
will be not "properly engineered" and generate and radiate RF noise of 
sufficient amplitude to be bothersome?
How do those two probabilities compare?
