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 =3D 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.

here I have a high noise level and am not hearing any thing
other  than local


signals.

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.
