I'm cross-posting to these groups as I believe them to be relevant.

Going Northbound on the M1, between Junctions 18 and 19 keep your eyes to
the left hand side of the road (well, obviously not if you're driving...)

You'll see, over the spread of about a mile, loads and loads of masts - They
are arranged in groups of about 8 or so (travelling too fast to count
properly). The masts go straight up and have no equipment hanging from them.

There were, what looked like, hundreds of masts. Varying heights.

Any ideas what these might be? Just curious!

I always thought it was Rugby or was it Droitwich? - Radio Four LongWave plus
60Khz time signal etc etc etc I think??

Also think BT owns the site/service, but not for much longer. Heard that most
will be pulled down in the next year or so, might have been dreaming it though.

Basically they transmit the "PIPs" you hear on the hour on BBC Radio and TV. The
PIPs are broadcast on radio freq 60khz and controlled by an atomic clock. Used
by all maner of people to set their clocks - BBC, Computers, Dare I say British
Rail. My Living room wall clock is set to standard time from the 60Khz
transmitter at Rugby (it has a little in built receiver which captures the
"PIP"s)

However, more recently GPS satellites and Internet timesources have become
alternates, so it's days may be numbered.

Next time you pass, put your foot down. You may start to feel your body heating
up if you linger too long under the antennas ;-)

198Khz long wave comes from Droitwich which is down
Worcestershire way. The masts are visible from the M5
somewhere around junctions 6 or 7.

If you want to see a *real* antenna, have a look at:-

MSF, amongst other things. 198 kHz long wave comes from Droitwich.

Isn't there anything remaining of the BBC antenna farm at Daventry? This
would be around J17(M1).

Spoke to a bloke who works there recently on 2 metres. They have sold the
big collinears to some African nation and they have now gone.

Most of the other towers are open to offers. If you fancy one in your garden

No - you're not dreaming.

The 16kHz service, GBR, that BT ran from Rugby has closed. The Royal
Navy, who were the main customer, have decided they no longer need the
service. It used to be used for morse and, more recently, RTTY (radio
teletype) transmissions, primarily to submarines (that frequency is so
low that it'll penetrate a great deal of water).


According to the GB2RS (RSGB News) broadcast of 30 March 2003, a
consortium are modernising a VLF transmitter site at Anthorn in Cumbria
under the Private Finance Initiative. It sounds as if that site has
taken over from GBR.

On Rugby, the same broadcast said, "It's understood that most of BT's HF
services from Rugby have now ceased, and that the site is likely to
close next year."


The same broadcast on 20 April 2003 reported that GBR closed on 31
March:

As many listeners will now be aware, GBR, the Rugby VLF station
on 16kHz, closed down on the 31st of March. Bob Harrison, G4LMF,
sent us the text of the final transmission. The following
message was sent at 2400UTC on the 31st of March: "VVV DE GBR
VVV DE GBR. After 77 years, three months of almost continuous
operation, the GBR 16kHz service from BT Radio Station Rugby
ceases today. A thank you to our customers, mainly the Royal
Navy, without whom the service would not have been required and
whose co-operation has enabled the service to run so smoothly. A
big thank you must go to all of those who over the years have
been involved in the design, construction, maintenance and
operation of GBR. They can feel very proud of providing a
consistent high level of reliable service and a job well done.
This is the final transmission and GBR will now be shut down for
the last time. DE GBR GBR QRT."

(for those that don't understand the prosigns, VVV is a general call to
all stations - though CQ is used in the Amateur Service, DE is from, GBR
is the callsign of the station, and QRT means closing down).


The closure of GBR leaves a lot of antenna kit that will likely be
removed. Much as some people lament their passing, these installations
require a lot of maintenance to be left standing safely. I believe this
was partly the reason that the "Elephant Cage" (HF direction finding)
array at RAF Chicksands in Bedfordshire was removed; my understanding is
that not only was it obsolete for military purposes, but it was, despite
appearances, largely made of wood and needed significant upkeep.


Quite apart from the likely removal of the GBR antenna, it sounds like a
whole load more is coming down at Rugby as well. The consensus from the
web is that BT is likely to completely vacate the site, probably in
about 18 months' time. Though BT still have the contract for MSF (the
60kHz standard frequency / time signal transmission) until 2007, there's
talk that they're going to move that operation to a new site.

Marine HF (another job of BT Rugby - in fact, I believe the sole BT run
marine HF station now that BT Portishead Radio has closed) is probably
of limited lifespan now with the introduction of GMDSS. I wouldn't be
surprised if Rugby's marine services soon become obsolete. The marine
distress watch on 500kHz using Morse has ceased - though I don't know
the current situation with 2182kHz HF phone.

As others have said, the 198kHz standard frequency and BBC Radio 4 AM
transmission is from Droitwich, Worcestershire. I don't know who the
transmission contractor is for that - but it's almost certainly Crown
Castle International who have all the main BBC transmission contracts.

Had me going for a bit then, I was trying to imagine what a LF 4 x 5/8 wave

The HF station is closed, the VLF is now off the D list, it has been taken

How many horns a day did you have then? ;-)

Mind you, I'm not surprised they were impressed with a good horn. I'm told
