So, where are these "repeaters" you blithely cited the existence of?


They existed in the 60's. That's all I can tell you. After that, I became
100% digital at Intel Corp. Doesn't the present existence of 650K of web
pages involving "Power Line Carrier" count?


In a word, NO. Not worth the paper they aren't written on. Next week, I am
going to be doing some library research at a technical library, and I am
going to scan through the issues of IRE Transactions on Power Equipment, or
whatever the name was pre-IEEE, from 1950 to 1965 or so, and I'll get back
to you. I already know the answer, and I think so do you. For your part,
why don't you start a movement within IEEE to put their pre-1990
publications in their digital database?

It was the American Institute of Electrical Engineers although I chose to
join the Institute of Radio Engineers instead, for obvious reasons. :-)

I assume 400 KHz Power Line Carrier is hardly anything like BPL which,
I assume, is a lot broader banded than that. Power companies use Power
Line Carrier equipment to control sub-stations from a central location.
They don't generally use it between the sub-station and residences so it
is usually not a problem for hams. But I have heard of power companies
using Power Line Carrier systems to read their meters under computer
control. Do you have any other specific questions? I'll try to dust off
my failing memory and answer them.
