[TenTec] Ground Loops in the Station

[Rick - DJ0IP / NJ0IP]

Jim,

Since I have been a ham, I have heard about, read about and been warned
about ground loops.
You say the entire concept is plain wrong. 
I don't challenge that statement but I would like to understand why.

I have read lots of stuff on grounds and it appears to me that there is
nothing than anyone says or writes that isn't contradicted by someone else,
elsewhere.

I assume most people are in the same boat I am; I have no clue what to
believe on this topic and in the meantime when someone asks me how to ground
their station, I respond with "I haven't a clue; read the ARRL Handbook."

I understand that this topic is beyond the scope of this group or emails,
but perhaps you could point us to a good source for reading about this.
Like everything else on the web, you never know if you can trust the source
or not.

Any tips?
Tnx.

73
Rick, DJ0IP

The entire concept of a "ground loop" is plain wrong, and leads to false
design concepts like what you have outlined. A discussion of all of this is
outside the scope of conversation on an email reflector. .

Yes.
