Deleted as irrelevant and potentially inaccurate:

"It should be noted that in the southern-central part of England, the Five Live MW signal is not strong, due to few transmitters, as Droitwich or Brookmans Park are the nearest."

Actually in the south east at least there's a very strong signal on 909 kHz, although I couldn't name the tx site. Lee M 17:45, 18 January 2007 (UTC)[reply]

I think he means central southern England where the distances to Droitwich and Brookmans Park are large. Cities like Brighton and Portsmouth have low-power MW transmitters to fill in the coverage.

Single frequency network

[edit]

AIUI the term Single Frequency Network came relates to COFDM-type stuff. When overlapping AM transmitters operate on a single frequency, I believe the customary term is "synchronised group". --Harumphy (talk) 19:30, 17 May 2009 (UTC)[reply]

WW2 service

[edit]

The article states During World War II secret messages were sent to the French Resistance using the transmitter. The messages were read during normal programme broadcasts and references a story on the BBC Hereford and Worcester website to substantiate this. I am almost certain both are incorrect. I'm not an expert on this, but I believe the BBC National Programme from Droitwich was shut down at the start of WW2 to prevent enemy aircraft from using it as a navigation beacon, and transmissions only restarted after the war. The 'Civilian Receiver' domestic radios manufactured during the war did not have LW coverage for this reason.

There were high powered transmissions to Europe from somewhere in East Anglia during the war, but these were nothing to do with Droitwich which is a poor location for transmission to continental Europe. Hopefully an editor with suitable expertise can update the article. --Ef80 (talk) 18:50, 19 October 2009 (UTC)[reply]

This BBC Engineering document confirms that the LW transmissions ceased at the start of the war, but states that a new high powered MW service to Europe based at Droitwich started in 1941 using new transmitters. I suppose it all depends on what you define as 'the transmitter'. --Ef80 (talk) 19:22, 19 October 2009 (UTC)[reply]

Reduced power?

[edit]

Listening to TMS in June 2013 I have the impression that the 198 kHz transmission power might have been reduced by about 6 dB to perhaps 100 kW. This would save energy costs and would also eke out the 'rare' amplifier valves. Or maybe background noise is just much stronger than it used to be.

Incorrect information in 1st paragraph

[edit]

"The masts can be seen to the east from the M5 motorway, between Droitwich and Bromsgrove, as well as to the west from the Herefordshire/Worcestershire border" This is impossible as Herefordshire is west of Worcestershire. This should probably read "as well as to the west from the Warwickshire/Worcestershire border" though I can't confirm this is true. The masts can be seen from the Herefordshire/Worcestershire border 22 miles to the south west from the top of Malvern Hills but does require exceptionally clear weather.
