After some correspondence with Charles Counselman, W1HIS, I have been
made aware of serious short comings in my testing procedure. Charles
pointed out that I could not make accurate enough to insure that what I
was
measuring was in fact TI and not common mode effect due to micro
imbalances
in my equipment.

Upon further thought and reflection, the fact that placing a number of
ferrite beads
along coax stops the "ingress" suggests that Charles is correct and
that it is
common mode effects I am measuring.

From some simple tests to check the balance of my BALUNs, I am
convinced that
I have errors of at least 15%. Even my trusty R390's balanced input is
far from a
"perfect" balance over the 5000KHz to 30MHz frequency range.

Charles Counselman's research into common mode effects and how to
reduce
it are a God send to my receiving pursuits.

I am grateful for his help in understanding where I went wrong. And I
am sorry
for any confussion I may have caused.

For a very inexpensive aid in RFI/EMI reduction, check out

scroll down to filters and take a look at the CURTIS, Mfg.# -
F1600CA03, 3A filters.
These have been a great help in stomping RFI before it gets started

Thanks, good info. The good news is the solution works for either
reason.... although Devoldere's/Bryants chokes remain a terrific tool
as well as the distributed beads.
