[Elecraft] K-Line Addition - DC Power Supply (Suggestion)

[Ron D'Eau Claire]

Regarding the certifications for mains power equipment running off of various mains circuits in various countries, don't forget that Elecraft has already done that with the KPA500.

...Don mentioned certifications for each country. Don't forget the power source is often different from country to country (50/60 hertz and 120/240 vac) or even within the country (look at Japan). Building a supply that meets all these requirements adds expense. Look at the issues an internal power supply causes in the KPA500 even without the concerns of interfering with a receiver.
