In reference to my earlier posting regarding a severe noise problem
on frequency 11955 kHz - The high noise level is still there with and
without the outdoor antenna connected. I've returned my Kenwood
R-5000 receiver to the local Kenwood service facilities (Cerritos,
CA) and am temporary using a Grundig eTraveller World Receiver until
my R-5000 is repaired and returned. However, even with the Grundig
have found that I have the same noise problem on 11955kHz. I'm using
three different antennae - one amplified vertical and two long wire.
Could the noise problem being thru the mains (117 vac house wiring)?
This doesn't seem logical as I am running the Grundig off of
batteries with no connection to the mains. Could the problem be
related to nearby Pt. Mugu Naval Air Station who does experimental
work for the Navy? Would all fellow SWLs who live in the central and
southern California check and see if they have any noise problem on
11955kHz? Thank you.

I'm in Ventura not far from you and I don't have any noise on 11,955
kHz.

To test your receiver disconnect the antenna and see if the noise goes
away. If it does then it is coming from your lead-in or antenna.

If the noise does not go away with the antenna disconnected the radio
has a problem or it could be coming from the AC power. If possible
operate the radio on batteries.

Use the portable to try to locate the noise source.

Try turning off the house breakers to see whether the noise is coming
from some appliance in your house.
