Ham radio Interference

Morse Code? Does anyone still use that? I thought it had died a death a
few years back.

I have a Ham Radio enthusiast living some 200 yards away with a big set
of aerianalia. When he turns this in my direction and talks to his
contact, my picture on Sky jumps all over the place to the extent it is
unwatchable. Just like having the vertical hold set wrong. The sound on
my amplifier also cuts out when he is talking. Sky box is connected to a
video recorder by scart and then to the TV, in the next room, by RF
output (they don't make scart leads long enough).

(Turned on the electric keyboard the other day and there he was in
glorious SSB blasting out from the speakers)

I am also getting some mild noise-type interference on other occasions
but cannot be sure it is the same source.

Have been round to see him, nice chap, but he doesn't think he is doing
anything wrong and is not obliged to solve my problem. He has mentioned
some bit of equipment I could put in the 'line',even had a root around
his garage to see if he had one.

Does anyone know the legal position on this type of interference?

If I can't resolve it with him, to what body do I complain? Radio
Society of Great Britain? Ofcom?

Any advice would be welcome on the above or how I can minimise the
interference with a gadget.

I have the same issue with a guy living next door to me. When he's on
his HAM radio he comes through the speakers on my stereo, makes the TV
unwatchable and cuts off my broadband connection. I contacted the
RSGB (Kath Wilson) and was basically told that I was the one who had
all this faulty equipment and would need to purchase filters to try
and correct the issue.

The advice could be technically correct, but I think it's highly
unlikely that the RSGB would have given it to you in quite that way.

The guy causing the interference told me I
should have my house rewired!

If he did, he's probably wrong!

For some reason, I was suddenly the one
who was at fault ??

No. You're not 'at fault' - and I doubt if the guy next door is either.
It's probably just that your entertainment equipment doesn't work
correctly in the presence of strong radio signals, and may need a bit of
a 'helping hand' in the way of filtering, screening etc in order to
increase its immunity from such signals.

An innocent guy can't watch his own television or
go on the internet and it's my fault - I ain't causing the
interefence!

Of course it's not 'your fault'.

It was obvious that the RSGB look after 'their own'

No. While the RSGB obviously represent the interests of radio amateurs,
those interests do include living in harmony with their neighbours -
which the vast majority do.

and feel free to
go about the country interfereing with everybody's equipment and
couldn't care less - if you ask me their should be more policing of
this kind of selfish behaviour.

The 'policing' is done by Ofcom, with whom the RSGB have a reasonably
good working relationship.

As it turned out, there are certain 'products' you can buy on ebay
which will Jam the transmissions from a ham radio which I am finding
very effective to this date ;-)

If you are indeed operating such equipment with the intention of
interfering with radio reception, you may find that Ofcom will be far
from sympathetic to any 'official' complaint you may submit concerning
the interference to you.

If you retrieve the rest of this thread, you will see that it has been
explained how various procedures exist for dealing with problems like
yours, the most important of which is to co-operate with the radio
amateur concerned - and to encourage him to co-operate with you. If the
two of you can't work together to solve your problem, it's only going to
delay the finding and implementation of a satisfactory cure.

Only for a ship's wireless operator licence. Morse code is a low tech
low bandwidth signalling method that can allow DX operation on milliwat
power (hundred kilometer path lengths for 100mW transmissions when using
12wpm or slower and reciever filter bandwidths of a 100Hz or less).

Morse code (CW) still has an enthusiastic following amongst a(n
admittedly) small group of the radio amateur fraternity.

You obviously haven't listened much 'down on the CW end' of many of the
amateur bands. A minority? Undoubtedly. But a "small group"? Hardly.

That's just a paraphrasing of my last paragraph. ;-)

You are at liberty to watch your TV, go on the internet or listen to your
stereo.

However, if your broadband modem does not comply with the terms of the CE
approval with which it was issued, or if your stereo performs in a manner
outwith its specifications (as a radio receiver), or if your TV doesn't meet
the minimum regulatory EMC standards, then the responsibility lies with you,
and you alone.

Why should your neighbour spend his time and money fixing your faulty
equipment?

If your car ran out of petrol outside his house, would you expect him to pay
for the next tankful?

I'm just suggesting that there is actually a surprising amount of morse
going on on the amateur bands. Admittedly, those who regularly (or can)
use morse are a minority of radio amateurs, but I wouldn't say that they
were a 'small group'. But, anyway, it's irrelevant to the subject of the
thread.

Yes.

Clearly thinking isn't your strong point.

Possibly true. But how would I know without asking? It seems a bit of a
minority sport.
