Daisy Chaining the equipment does not work, remove what you have and start 
over.

I use a 3 foot piece of copper pipe attached to the bottom of the radio 
bench.  Each piece of gear is tied to the copper pipe with welding cable 1/0, 
I made up special connectors and soldered them on to the wire and connected 
to the wing nuts on the back of the equipment. The Wire is connected to the 
copper pipe with stainless steal hose clamps with Penetrox (electrical 
compound) in between.  I then have two welding cables (side by side) tied to 
an 8 foot ground rod that was driven into the concrete floor (drilled hole 
with concrete bit first).  I have about 2 1/2 feet from the ground rod to the 
copper pipe.  I also tied a ground to the tower and to the cold water pipe to 
keep earth ground exactly the same everywhere, this allows  the receiver to 
hear better.

I operate full legal limit and I have inspected the neighbors next door while 
I was at full legal limit into the log periodic with only slight interference 
into the phone that was cleared up with plug in phone filters from Radio 
Shack.

Spend a lot of time on your RF grounds and do them right, it pays off with 
better sensitivity and better neighbor relations.
