      Found this on a site for radio enthusiasts. The OM what originally posted it criticised todays BBC for being lax about sound and signal quality. whilst he has a point, this is more to do with cost cutting and limitations with the DAB format wihch was obsolete by the time it was deployed.

      This monitoring station still exists today and the engineers there are just as meticulous, but it is now at Caversham Park in SE England (and has been for some time, probably since the 1970s) along with the better known one they use for monitoring foreign broadcasters.

      Today it works closely with Ofcom and listens out (or looks out) for interference sources to licensed broadcasters, as well as logging BBC content for compliance purposes – but Auntie don’t like to shout about it (its existence may well have been classified for a while).

      PDF below. Its aimed at a technical audience across Europe (probably the EBU/UER, as dimensions etc are shown in both Imperial and Metric units).

        Wow. 11 Kilowatts at 3 phase? Lotta juice used for signals intelligence in them days.

        Nowadays they got things like Awacs and satellites for better coverage. Ground stations more reliable but you get better reception the higher your aerials are.

          I think thats why they shifted to Caversham. Antennas are in a higher bit of South Oxfordshire.

          It is one of the highest bits of SE England.

          Incidentally although the cat I meowed with as a somewhat bizzare “cross species male bonding exercise” decided to delegate mouse catching duties to me as the “alpha male” (with the predictable result the mice all got away), he would signal like a covert sniffer dog whenever he heard my radio scanner go off on the police frequencies.

          I lived in the flight path to RAF Benson where TVP kept their heli XA97. it was and is also a main route to several civil and military aerodromes (another thing Auntie did was make sure anyones band II transmissions (BBC, IRN or even pirate) did not cut into the aviation band) Whenever this aircraft flew overhead, he would go and sit on the wheeled bin and look up at it. He never did this with any other aircraft and there were of course loads.

          I did not openly train or encourage the cat to do this, but he seemed to pick up on my reactions to hearing the police traffic or the helicopter and that it was something to be aware of. Given some of the things I was involved in at the time this was a welcome extra pair of ears :laugh_at:
