Hi Rik and LF
Thanks for pushing me into doing some thing about my 500kc/s noise.
You would think a bloke my age would have got to grips with this
earlier. You were dead right The noise was coming from a DVD player
that was on the face of it switched off. Using a small MW radio
proved otherwise. I have to pull the plug out of the wall to shut it
up. Surgery with a hammer is planned next!!!
Oh yes I am now hearing things again hope to hear you and have that QSO.

Hello Pete,
I found out that 90% of the noise on 500kHz came from inside my own
house.
A lot of electronics is running of switched PSU's and you need just
one of
these oscillating near 500 kHz to get a lot of noise.
I took a small portable AM radio (tuned to the lowest end of the
medium wave
band = abt. 520kHz) to locate the noise sources. Use the ferrite
antenna to take
null bearings.
After replacing a couple of 12V switched PSU's by good old linear
ones
noise was down by 10's of dB.
Another source of noise are energy saving lamps. You can locate them
the same
way.

Hi Mal and LF
I would like to be on for two way QSO's however its the old
story
here I have a high noise level and am not hearing any thing
other than local
signals.
I was on the Suffolk coast for this years holiday. I only had
a Kenwood
TS50 and a 40 metre dipole up. I was hearing just about every
thing on
500kc/s. Its not as though I live in a high density area apart
from a neighbour
either side the nearest other is about 1/4mile away but I do
have 11kV at the
bottom of the garden which to date has not been a problem. So I
suspect an
insulator but the noise is not general it is not affecting HF
at the moment.
I have an 8 foot Octagon tuneable and rotatable loop that I
am playing
with at the moment but so far no real improvement.
Sorry for the tale of woe but we are working on the problem.
Chris XIZ has suggested X band so I may try that shortly.
