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.

other than local

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.
