[RFI] Power Lines

[Jim Miller]

Does the RFI from DC lines tend to be less or more than that from AC lines?
Is there a way to tell if the lines are DC or AC?  Can you "listen" to them
or something?  I have HV lines running across my property in the country.

Tnx es 73, de Jim, KG0KP

SHOCKED to learn that some of their main transmission lines are actually DC.
I have always assumed all the main power lines are AC. Even studies I've
seen regarding health issues from power lines reference AC.
