[TenTec] Power supply types

[Kim Elmore]

This is an apples vs pecans question.

Better-stated questions:

What's the probability that a properly-designed and engineered linear 
power supply will radiate  RF noise of sufficient amplitude to be 
bothersome?

What's the probability that a properly-designed and engineered switching 
power supply will radiate  RF noise of sufficient amplitude to be 
bothersome?

Answer: unknown. likely small but equal.
