Cuhulinman - See my reply to David's post. I'm really just trying to learn
a little about power supplies, and was wondering if a power supply in my
shack would eliminate power line noise from the house. The inverters I
mentioned are not what I would use at home, but they brought up the question
of what's the difference between switching and linear.

I could use batteries, but I want a more permanent solution in the shack.
Though, it's likely that power line noise is minimal compared to radiated
noise picked up by my antenna, so I probably really don't need a separate
power supply.
