As far as I can see, the Radio Ulster medium wave service on 1341 kHz
has closed but Radio 4 continues on 720 kHz. This seems illogical as
I assumed Radio Ulster would be the pre-eminent service. Surely R4
DAB coverage (on the main BBC multiplex) will be at least as good as
Radio Ulster so what is the logic of retaining one and not the other?
It cannot be Test Match Special as this is available on Five Live
Sports Extra.

All of the R4 MW fillers continue to broadcast. The Beeb have said that
the Radio 4 LW 'opt out' programming (which is also carried on the MW
fillers) will cease at the end of March next year. From that point there
will be no need for the MW fillers to continue, and some are expecting
all of them to be switched off in April.

As for 198 LW itself, who knows, the energy companies still have
hundreds of thousands of teleswitches in use, so fortunes are
intertwined with that mess.

If the LW transmitters are only to be used for radio teleswitching, can the
carrier be funded in power or turned off when switching commands are not
being issued?

It's 25 BIT per second data carousel, that has to address various
batches of devices with different tariffs. I think it has to be more or
less continuously transmitted ?

Anyway, switching Droitwich (etc) on and off is going to shorten the
life of the valves etc even faster !

Reducing the power might work. I've rigged up a means in recent weeks to
record the exact switch off and on times for my mothers' antique
Teleswitch. They are On 23:00, Off 07:00, On 13:00, Off 15:30.

Only vary by a few seconds either side of 'bang on', so clearly the
device is being kept on track as far as clock accuracy is concerned, but
there doesn't seem to be any adjustment of the on/off times (that would
be helpful to National Grid Ltd) so I actually wonder if the system is
still being used dynamically.

No 1hr change of time on Oct 29th, those times seems to be GMT all year
round.

So no better than the clockwork switch on my supply (except no lunchtime
top-up)!

I occasionally check with a test probe whether the storage heater is on
or off (the little neons in the switches died years ago) and never far out.

I think they’ve given up on the dynamic load balancing for E7. My smart
meter is configured for E7 and switches to the low rate at 0030 GMT all
year round.

So in conclusion, if/when 198 is switched off, nothing catastrophic is
going to happen. I'd expect the internal clock to use 50 Hz as a timing
reference, so the big question is can it keep counting in a power cut !

OVO are certainly in no rush to replace the kit with (in my mother's
case) a dual phase/dual tariff super-dooper smart meter/switch solution,
(because they tell me, they still don't have one yet !)

Also, as an aside, where did 720 kHz (417 metres) come from? I cannot
find it as one of the old BBC wavelengths. As far as I can see, it was
first used by LBC. Is it one of these 'international' frequencies
that can be used at low power by anyone?

Well, it's an interesting question. The IBA had never intended to use
the frequency (719 pre 1978) but owing to planning delays for Saffron
Green they had to find two temporary allocations, at the bottom end of
the MF band for a temporary lash up at Lots Road power station.

They obtained 719 and 557. 719 didn't seem to be an issue, but 557 was
being used by by Radio Veronica, an offshore pirate station. The IBA dug
their heals in, and there was a bit of a kurfffle, but Capital launched
on 557 (539m).

Anyway, LBC moved to 1151kHz at Saffron Green in May 1975, but the Beeb
resurrected the Lots Road site and used 720 kHz from 1979, after a
year's worth of complaints from London R4 listeners that they couldn't
receive LW properly (as of course R4 moved to LW in Nov 78)

720 has been used in N.Ireland for R4 since Nov 78. I can't find any
record of it being used anywhere else in the UK other than for R4 in
London and NI ?

Thanks for that. It looks like the use of the frequency was
negotiated with another authorised user, presumably elsewhere in
Europe. I assume Northern Ireland would be less of an issue in that
regard.

Was it Lots Road where they had the very advance sophisticated system
for the transmitters. They let the phone ring n times and the
transmitter reset.

Someone from ITA, IBA (or whatever they were called that week) told me
about it many years ago.

Belfast Telegraph - Thursday 11 March 1976


BBC RADIO IN NORTHERN IRELAND

Radio 4 417 m 719 khz





The Stage - Thursday 13 September 1979

New frequency
"The long wave reception problems remain in some areas," said Miss Sims,
"but in central London a new medium wave frequency should provide an
alternative for listeners who live in steel framed buildings or suffer
electrical interference." We understand that the new frequency is to be
720kHz (417m) which should improve the Radio 4 signal considerably in
the daytime.
However, some interference may be found at night because the same
frequency has been allocated to a German station.
Ian Mclntyre's desire for flexibility, something he plans for Radio 3 of
which he is now controller, is, however, one of Monica Sims's principal
aims. But she is quick to point out that this does not mean doing away
with long established and popular series which are. as she says, "part
of the daily lives of Radio 4 listeners."

The German station was Langenberg WDR2 (Ruhrgebiet, Nordrhein Westfalen).
I think it was 200 kW.

Yes it did, and was apparently not welcome. 720 (and 558 kHz which
Spectrum/Panjab Radio uses) are carriers easily visible as patterning in
analogue TV video. Used to get into everything there.

Would this not have caused similar issues at Lots Road, or was it
because it was a shared mast? Surely this problem must have been known

My security package (Bitdefender) says the link is suspicious then
comes a message 'Not found'.

I know there was no TV transmitter at Lots Road but I thought the 720
kHz signal might be interfering with the TV receivers (like 5G, though
I have never heard of this happening). If this was a known problem,
why would they put a MW transmitter on a TV mast rather than adding it
to Brookmans Park or Saffron Green (as NI did at Lisnagarvey returning
to topic) or any other suitable high building?

why would they put a MW transmitter on a TV mast rather than adding it
to Brookmans Park or Saffron Green (as NI did at Lisnagarvey returning
to topic) or any other suitable high building?
I wasn't talking about TV receivers being interfered with. The problem
was the AM signal getting into the baseband video and audio circuits of
the TV transmitters at the site, and so affecting the transmitted signals.

I understand it was relocated to Crystal Palace when Lots Road power
station was scheduled for demolition.
Yes it did, and was apparently not welcome. 720 (and 558 kHz which
Spectrum/Panjab Radio uses) are carriers easily visible as patterning in
analogue TV video. Used to get into everything there.
Not so much or a problem now TV is digital !
Would this not have caused similar issues at Lots Road, or was it
because it was a shared mast? Surely this problem must have been known
about.
There was no TV transmitter at Lots Road
Not a unique problem though

I may have told this story before, but even so, you're going to get it
again :-)

When I first started with the BBC, the shift AS Tel E [1] had started
at AP before the war. Apparently, it was the devil's own job to keep
the transmitters there out of the vision signal system, to the extent
that all the vision apparatus was housed within double copper boxes,
with the seams continuously soldered.

Even quite low power VHF transmitters could be a problem with RF because
often the antenna might be not far above roof level.

We once had OB unit used our teambase for an OB of a climb on Ben Nevis,
they had a scanner and comms vehicle in our car park. They tried a
camera outside for a general view of the Ben but were suffering from RF
interference. They said they test equipment at Brookmans Park and
Crystal Palace, we explained that we had a lot lower power but the
antenna were less than 90ft agl.

Our workshop was RF screened because of that.

The site is hosted at Dreamhost in the US.

Maybe your DNS is resolving it to a different IP address from most other

For me, using OpenDNS in the UK, txfeatures.mb21.co.uk resolves to

Also, as an aside, where did 720 kHz (417 metres) come from? I cannot
find it as one of the old BBC wavelengths. As far as I can see, it was
first used by LBC. Is it one of these 'international' frequencies
that can be used at low power by anyone?
Well, it's an interesting question. The IBA had never intended to use
the frequency (719 pre 1978) but owing to planning delays for Saffron
Green they had to find two temporary allocations, at the bottom end of
the MF band for a temporary lash up at Lots Road power station.
They obtained 719 and 557. 719 didn't seem to be an issue, but 557 was
being used by by Radio Veronica, an offshore pirate station. The IBA dug
their heals in, and there was a bit of a kurfffle, but Capital launched
on 557 (539m).
Anyway, LBC moved to 1151kHz at Saffron Green in May 1975, but the Beeb
resurrected the Lots Road site and used 720 kHz from 1979, after a
year's worth of complaints from London R4 listeners that they couldn't
receive LW properly (as of course R4 moved to LW in Nov 78)
I understand it was relocated to Crystal Palace when Lots Road power
station was scheduled for demolition.
Post by Mark Carver
720 has been used in N.Ireland for R4 since Nov 78. I can't find any

Thanks for that. It looks like the use of the frequency was
negotiated with another authorised user, presumably elsewhere in
Europe. I assume Northern Ireland would be less of an issue in that
regard.
720 was in the 1975 plan with 4 transmitter for UK.

Belfast 0,5 kW
Londonderry 0,3 kW (synchronised with Belfast)
Coventry 0,5 kW
London 0,5 kW

As far as I can see, the Radio Ulster medium wave service on 1341 kHz
has closed but Radio 4 continues on 720 kHz. This seems illogical as
I assumed Radio Ulster would be the pre-eminent service. Surely R4
DAB coverage (on the main BBC multiplex) will be at least as good as
Radio Ulster so what is the logic of retaining one and not the other?
It cannot be Test Match Special as this is available on Five Live
Sports Extra.
All of the R4 MW fillers continue to broadcast. The Beeb have said that
the Radio 4 LW 'opt out' programming (which is also carried on the MW
fillers) will cease at the end of March next year. From that point there
will be no need for the MW fillers to continue, and some are expecting
all of them to be switched off in April.
As for 198 LW itself, who knows, the energy companies still have
hundreds of thousands of teleswitches in use, so fortunes are
intertwined with that mess.
If the LW transmitters are only to be used for radio teleswitching, can the
carrier be funded in power or turned off when switching commands are not
being issued?
It's 25 BIT per second data carousel, that has to address various
batches of devices with different tariffs. I think it has to be more or
less continuously transmitted ?
Anyway, switching Droitwich (etc) on and off is going to shorten the
life of the valves etc even faster !
What do the Danes do at Kalundborg? I understood they broadcast
shipping forcasts and news summaries only with long periods of
silence.
About 2,5 hours per day 50 kW,
the rest of the day 100mW.

Thanks. I thought it was something along these lines. I was wondering
more how the transmitter operates part time. Can a transmitter easily
be turned on and off or does it continue to operate in silence? I
remember from Tony Currie's book about Radio Clyde (recommended by
Mark) that the MW transmitter stayed on all night with station idents
mandated by the IBA every 15 minutes.

He tells of one listener they thought was listening all the time, so
at 45 minutes before the start-up TC opened the line to the
transmitter and broadcast a good morning message to this lady, who
then phoned the studio two minutes later.

Usually things are more reliable if not switched off and on - isn't
there a light bulb somewhere that has been working for over a hundred years?

I think there was an improvement in reliability when the BBC UHF TV
services went 24 hours.

Famously when Tommy Flowers proposed using valves in Colossus at
Bletchley Park, many were sceptical but he had worked with valves at
Dollis Hill and knew they could be reliable if treated carefully.






By the way posted in this elsewhere in a discussion about the snow today.

In the 1970s or 1980s, we had a fault at work at a fairly new site which
coincidentally was accessed by a SnoTrac.

There was an antenna fault that dragged on for weeks because of the
limited access - daylight hours only which are short in the Highlands in
mid-Winter.

The riggers had equipment etc to get up to the site (1600ft asl) so
bought a small sledge which meant that for a short time, the BBC had an
official sledge.

It was outside a fire station in America when someone first noticed its
great age; it may still be, though now has its own special power supply
to protect it. (Thinking about it, probably DC. And I'd expect slightly
under-run.)

Transmitters, certainly valved ones, would I think benefit from not
being switched off and on a lot. On the other hand, when we're talking
of any significant power, the electricity bill has to be weighed against
the replacement cost (including labour costs). I imagine there's a
compromise where they're kept powered in terms of HT supplies (and
filament supplies for valves) but not actually outputting kilowatts or
more.

be turned on and off or does it continue to operate in silence?
Usually things are more reliable if not switched off and on - isn't
there a light bulb somewhere that has been working for over a hundred years?
It was outside a fire station in America when someone first noticed its
great age; it may still be, though now has its own special power supply
to protect it. (Thinking about it, probably DC. And I'd expect slightly
under-run.)
Transmitters, certainly valved ones, would I think benefit from not
being switched off and on a lot. On the other hand, when we're talking
of any significant power, the electricity bill has to be weighed against
the replacement cost (including labour costs). I imagine there's a
compromise where they're kept powered in terms of HT supplies (and
filament supplies for valves) but not actually outputting kilowatts or
more.
They are now replacing valved transmitters for modern solid state ones
much cheaper to run and as power is expensive...
I think i this is what they actually did with the 198 kHz transmitter at
Droitwich ....
Was the story about there only being eight (?) valves in the whole
world fake news then? How did they justify the capital cost of
replacing the transmitter if a decision had been taken to close the
service? There again, are second hand AM transmitters very cheap to
buy?

Dot believe the story re the valves, several valve re-builders in China
and Russia.

They have to keep the 198 kHz on the go for time switching services so
they it seems have worked out that a new Nautel solid state TX is
cheaper to run and maintain thus Arqiva are spending a lot less on
power!..

Don't know re that but it does seems that its the price of mains power

I believe the railways have mothballed some Electric locos and are still
using Diesel them being much cheaper run!...

The train operating companies are blaming the cost of electricity.

For freight, it is easier to swap locos than for passenger trains, as
the vast majority of passenger trains are now self powered multiple
units, bought to match the lines they are for.

No, as i understand it its simply the price of electricity they pay
verses the cost of Diesel!.

Mind you Diesels can go most anywhere whereas electric loco's can only
go where the power lines or rails go..

I thought some routes had limited supply capacity and that

Diesel under wires is common practice. Steam, on the other hand is not

The environment thing is fairly recent, but until they got rid of coal,
diesels made much less pollution per horsepower hour than electric. If
you look behind the sales talk, the National Grid is a horribly
inefficient way to go from fuel to wheel, whereas a well designed diesel
can be as efficient as any land based power station with none of the
transmission losses. The Powers That Be now use the CO2 emissions of
renewable sources as a marketing point to make it easier to sell the
wires. Electric (Be it trains, buses, vans or cars) also moves the
pollution from the point of use to somewhere else. Cities are cleaner,
while the countryside gets the pollution.

By the way,I count the way that renewables take up *lots* of land to be
a form of pollution, especially if you consider the pollution caused by
making and siting wind turbines and solar panels. Even tidal power can
wreck the environment in the estuary.

The chap who got an award for his work on wind power stations was on the
radio this morning, claimed he thought they were beautiful but of course
he could not see any from his home!

They typical bribe areas having them - I bet the same people used to
criticise the nuclear industry when they similarly gave grants to areas
near a nuclear power station (perhaps we should follow the wind power
people and call them farms as it sounds better!).

They make promises to reinstate the sites but I have read reports of
turbine towers replaced by bigger one but never read of the hundreds of
tons of concrete in the ground being removed!

Then there are the whole networks of roads to the sites. In this
newsgroup it is amusing to think of the moans when a 50ft tower for a
transmitting station was put on a hilltop!

Executive summary from their own documents:-

"Ending rail’s contribution to emissions by removing diesel trains.
Further minimizing carbon emissions through optimised cascade of the
cleanest compliant diesel trains."

The main document waffles on about hydrogen and battery powered trains,
among other things.

They also have a "We must make a profit" strategy.

Network Rail are not directly responsible for sourcing motive power, all
they can do is put pressure on the train operating companies, some of
which are now, once again, state owned.

Maybe LW will just go on till something major fails.

I do detect that the BBC are completely illogical with the mw shut downs.
Its as if there are several committees only responsible for a channel who
do not take to each other. Its about time the BBC became a broadcaster of
better quality stuff that has no way of being funded on commercial outlets.
It would be cheaper, and not so dumbed down. You get more technically
accurate stuff made in bedrooms on You Tube than the BBC seem to make now be
it radio or TV.

As far as I can see, the Radio Ulster medium wave service on 1341 kHz
has closed but Radio 4 continues on 720 kHz. This seems illogical as
I assumed Radio Ulster would be the pre-eminent service. Surely R4
DAB coverage (on the main BBC multiplex) will be at least as good as
Radio Ulster so what is the logic of retaining one and not the other?
It cannot be Test Match Special as this is available on Five Live
Sports Extra.
All of the R4 MW fillers continue to broadcast. The Beeb have said that
the Radio 4 LW 'opt out' programming (which is also carried on the MW
fillers) will cease at the end of March next year. From that point there
will be no need for the MW fillers to continue, and some are expecting all
of them to be switched off in April.
As for 198 LW itself, who knows, the energy companies still have hundreds
of thousands of teleswitches in use, so fortunes are intertwined with that
mess.

It's always been a balancing act: if they _only_ did certain stuff, the
calls for the abolition of their public funding would avalanche (they're
getting pretty strong as it is, sadly IMO).

Where it _is_ a bidding matter, I tend to agree - with legislation to
protect where possible. But that's really only possible where there is a
geographical anchor, like Wimbledon: for international events like world
(football) cup, and Formula 1, if such legislation gets too restrictive,
the organising bodies (such as FIFA) will just take their business to
other countries. (You may say, what if a lot of that organisation's
audience is in the UK? Well, they're businesses - they're not interested
in that audience if it isn't willing to pay. That'd only be relevant if
a lot of their audience is in the UK _and_ would only pay if the events
were in the UK.)

Where it_is_ a bidding matter, I tend to agree - with legislation to
protect where possible. But that's really only possible where there is a
geographical anchor, like Wimbledon: for international events like world
(football) cup, and Formula 1, if such legislation gets too restrictive,
the organising bodies (such as FIFA) will just take their business to
other countries.
Some events, perhaps like Wimbledon want the coverage on Free To Air to
attract more participation in the sport.

Obviously others, like football, have an audience don't play the game
and will pay large amount to watch their own team.

My view is they should surrender high cost events such as the World
Cup to ITV and concentrate on the public service obligation.
Even though the majority choose to watch those events on BBC?

Given a choice yes, given no choice ITV get all of the audience, what's
the problem ?

So why don't ITV leave them for CH5 to cover, what's the problem?

None, the point is when an event is on the BBC and another channel, most
viewers will select the BBC to avoid the ads.

If the BBC are not covering the event, then all the viewers will select
who ever is showing it instead. They don't care who's showing it.

To be honest, there are very few sports events that are duplicated on
BBC and ITV (or where ever) these days.

If there _is_ duplication, at least if the BBC are covering it at all,
it's likely to be between multiple BBC channels. Applies to a lot more
than sport, of course.

There should be a place on the ballot paper for 'None of the above', and if
enough people filled that in, the system might start to change. - Jeremy

I don't tend to watch sport but I think it is just the final that will
be on both (or more).
