You don't say what you've tried already or what sort of age your stock
is, but clean wheels and tracks are the first step. Then make sure the
interference suppression components are still fitted to the motors.
That should get rid of most, if not all interference, but there are
other steps to take if necessary.
OK, clearly I am a non-techie model railwayer!
I haven't tried anything, as I don't know what - that's why I posted.
I have Hornby/Bachman OO guage engines from 2 to 45 years old. We get
horizontal dotted lines on all TV's when the trains are running - I
don't think it is engine specific. The trains are in a shed in the garden.
Does this help?
There was quite a lot of comments about this on mremag not so long back,
worth reading those. But basically its a case of sort out your tv arial and
cabling - they are most likely the problem.
Yes I agree with Simon ....... how old is your aerial installation
( and for that matter your TV ) ?
Poor shielding can cause problems.
PECO do a set of "Shows You How Booklets - Series 2" which includes
'10 Curing TV Interference' http://www.peco-uk.com/Publications/Otherpubns.htm
You could also consider an aerial fitted with a balun
Contrary to what that article states, a balun reduces neither noise nor
interference. It removes *standing waves* which is critical for good digital
reception but not so important for analogue. One aerial brand in particular
(Televes) has a _combined balun and masthead amplifier_ which is possibly
where the confusion originated.
These were the other solutions I was referring to, but I feel it's
better to try to eliminate or reduce the problem at source first of all.
Besides, it may not be Dave H's TV that's picking up the interference!
Actually, John Turner replied with what was my first instinctive
Or equally, today it could be the OP's TV, tomorrow the neighhbour's
TV, next week half the neighbourhood when he starts double
heading ;-). I just think ( with 20 odd years experience in RF
design / EMC issues) that trying to cure the problem at source is a
better first step than improving the immunity of the Freeview(?
assuming it is Freeview) box & downlead. I do, however, agree that
some Freeview boxes seem particularly sensitive to impulsive
interference, and in some situations a decent quality double screened
downlead will help / cure matters. I just don't think it should be the
first step in this particular case, particularly as the OP states "
all our TVs" rather than just one, and thsi might good old analogue TV
Oh yes, I do like Bill Wright's site, spent many a happy our browsing
the dodgy aerial installations part :-)
I absolutely agree with this, cable quality is absolutely paramount,
particularly with regards to Digital Television. You should also run
your wiring in CT100 grade cable.
I have no affiliation to this guy but I trust him implicitly.
Depends on one's location, aerial and performance of the freeview
box, I get 100% rock solid Freeview via a nine quid Screwfix aerial
and yards of 30 year old brown co-ax, I'm not on top of the
transmitter either: CT100 isn't absolutely paramount in all
circumstances. Fixing the problem at source is likely to be a LOT
cheaper and quicker than replacing the co-ax with CT100 or similar
double screened cable.
Possibly yes I agreee, but for that to work you must be in a pretty god
field strength region. I am in the middle of Wales (the Kerry tramway?)
and I get freeview service from Winter Hill near Huddersfield. I had
to go to a lot of effort for my telly. I learnt a lot about TV
reception as well. And I don't like heights either!
Gosh yes, having looked at the most comprehensive reception predictor
I know of for Freeview:-
and using random postcodes for Newtown, Powys I get no reception
predicted whatsoever! Must've been 'fun' getting reception round
there, I home the programmes were worth the effort ;-). I'm on the
edge of the New Forest, a few trees to contend with, but mostly water
between me and Rowridge IOW, hence I can get a good signal with old
Oi! Get it right! Winter Hill is near BOLTON!
Just trying to get my TV reception sorted. I think I'm a little too close to
Winter Hill - 6 miles so I can get strong signals with a bit of bent wire, but
getting good digital is proving troublesome
Winter Hill is the site of the original ITV North-West TV transmitter
completed in 1956; the current tubular steel mast was built in 1965. Emley
Moor transmitter is located close the M1 near Huddersfield. It's a 1,084
ft concrete and steel structure built to replace a mast, similar to that
at Winter Hill, which collapsed in 1969 under the weight of ice. Moorside
Edge and Holme Moss radio transmitters are a few miles away.
Not where I live. The aerial is on top of a nearby 14-storey tower block but
the cable is of 405-line VHF vintage. By the time the signal reaches me,
theres hardly any digital channel to speak-of.
