Oh, sounds like you are on the cleanup trail. Chasing out the noise is
often the major eye-opening event for state of the station. Trust
nothing, investigate everything. Measure, measure, measure. Signal to
noise. Take notes and save them. Good luck! 73, Guy.

Thanks to everyone who replied (many off list)! I will be working
through personal replies and follow-ups but have spent most of the
last 24 hours frantically investigating my station setup. I do have
some SEVERE new noise issues, and that vertical still needs to be
detuned. However...

Hi Paul:
I have a small rotating terminated loop receiving antenna which is located only
20 feet from a Inverted L - FCP (folded counter poise) transmit antenna.
The amount of noise re-radiated from the inverted L to the terminating loop is
very high, over S9. ( receiver sensitivity -128dB
I have made numerous attempts to "detune" my vertical over the past
6 years. I admit at this point I have no idea what I did wrong or
what to try next. I have what I believe to be evidence the vertical
is interacting significantly with the several Beverages, which of
necessity are close to it.
