Switch mode power supplies.

I hate switch mode power supplies. I hate wall warts. And I really really hate switch mode wall wart power supplies. Linear wall warts are bad enough. Found this while looking for a better (as in active) RFI probe. http://www.arrl.org/tis/info/cable-modems.html Switching-type AC adapters are indeed a disaster, at least as far as shortwave (or MW) radios go. But a good regulated and filtered "wall-wart" AC adapter has an advantage over an internal power supply that is little noted: as the voltage supplied to the radio by the adapter is very low, the owner can work on the inside of the radio while the radio is operating with no danger of a high voltage shock. There are pros and cons to everything. Best, Joe |
