Aberdeen ...... 1449 kHz
Bromley ........ 720 kHz
Carlisle ...... 1495 kHz
Derry .......... 720 kHz
Enniskillen .... 774 kHz
Glasgow ........ 720 kHz
Plymouth ....... 774 kHz
Redruth ........ 756 kHz
Tyneside ....... 603 kHz

Radio 4 UK, not just on LF, but MF too.

Are your sure about this? I don't see any mention of Aberdeen being
1449 kHz.

The Aberdeen transmitter is called "Redmoss"

Surely they will receive the long wave signal from Burghead?

No, Aberdeen is in the 'mush area' between Burghead and Westerglen

Likewise are you sure about Bromley?

There is a London transmitter - it used to be at Lotts Road, Chelsea, but
it's now at Crystal Palace

I don't see any mention of it.
Carlisle is 1485 not 1495. I am sure there is no local 720 kHz
transmitter in Glasgow as the signal is very weak.

Correct: Glasgow is served from Westerglen


( I assume it comes from Northern Ireland.)

the 720kHz that can be heard is Lisnagarvey - not mentioned in the list.

No, Aberdeen is in the 'mush area' between Burghead and Westerglen

That explains it.

I didn't associate Crystal Palace with Bromley.

On long wave (with very poor signal quality where I live!!!)

( I assume it comes from Northern Ireland.)

I see it is far more powerful than Londonderry/Derry.

Bit of a mix and mash up there. Redmoss was the first transmitter and also
carried BBC TV on 405 for a while. That got moved to Meldrum which also
did FM radio. ITV 405 added Durris which became the choice for UHF TV.
You'd not have thought they'd still need so many sites. Apart from the
small ones covering the many dead spots.

Redmoss also carried BBC 1 and ITV UHF services for a few days in January
1984, after the UHF Tx aerials at Durris were destroyed in a fire, as a result
of a severe blizzard.

Redmoss also had a temporary uhf station when Duris' transmitting aerial
failed.

When Redmoss first opened (1938) it was described as being 3 miles south
of Aberdeen. It's now well within the city limits. The vhf tv service was
a temporary measure which gave Aberdeen a service for 10 months before
Meldrum opened.

Durris, mentioned above, also has a BBC VHF/FM service from it.

And Redmoss is used by one of Aberdeen's commercial radio stations (Original
106.8) for a relay station, as a local fill in for the station's main Tx site
at Durris.

I suppose it depends where you measure from. It's far less than 3 miles
from the house I was born in - and that was built in '36.

Has Meldrum closed, then?

I remember that blizzard well as I was on holiday up there then. And
travelling by car in it. The road just disappeared. I was on the dual
carriageway leaving Aberdeen going on a visit to my brother who lived
south of it. I carried on at walking pace until the next exit from the
road and went back to Aberdeen. It was so cold that the heater in the car
stopped working at that slow pace and the screen started to freeze up.

No, Durris as far as BBC R1-4 FM are concerned is a highish power relay, a bit
like Crystal Palace's relationship with Wrotham for national FM services.

If you use the M1, you might have seen the Luton mf site well outside teh
town. It's now surrounded by houses.

no. Durris is a relay for those parts of the city & Deeside that Meldrum
doesn't rreach.
