Hi Don,
The KB2UYT articles from 2002 mentions a perimeter ring, but gives no
real details as to the construction and installation of the ring. An
article by KD7PEI in the 8/2008 QST gives more details, but still
fails to answer some questions such as:

Folks,
It is best not to rely on water pipes for any type of grounding.
Many homes have various combinations of steel, copper, plastic, etc. piping.
These are electrically discontinuous, often with purposefully inserted
"galvanic isolators".
The best ground is a proven, direct ground.

This isn't a difficult task. Just use a small file and scrape the paint off
around the holes. It took me all of 45 minutes from opening the packing box to

Here's an interesting piece on K3 transmit audio processing:

Hello Jim,
I use a very coarse sand paper to remove the paint. In K2, Elecraft did mask
