That new-fangled service that some predicted would never take off but is now known as BBC National DAB covering more than 97% of the UK population was launched thirty years ago today. Long before that, in the mid-1970s, the BBC had conducted tests into a potential digital radio service when a NICAM signal was broadcast from Pontop Pike at 47 MHz. These signals gave excellent results to fixed antennas, but not for portable omnidirectional antennas close to ground level. Subsequent experiments using COFDM, and so more like the DAB we know today, took place in South London in 1990 using TV channel 28 (531 MHz) from Crystal Palace with an active deflector at Kenley. These proved the modulation system worked, but also indicated that UHF was not the most suitable band. The following year, DAB was demonstrated in Birmingham using a frequency in Band III, to acclaim from journalists, broadcasters and industrialists. [Were any Wohnort readers on that coach?]. The first broadcasts as a regular service used five transmitters in the London area. The current Ofcom Technical Parameters sheet lists over four hundred sites across the UK, the Isle of Man and the Channel Islands. The offer continues to evolve, with three new DAB+ services added earlier this month.

Wohnort now pauses briefly to recall two other modulation systems whose development and implementation were being mentioned in the technical press at around the same time as DAB - NICAM (to add digital stereo sound to an analogue TV signal) and HD MAC (multiplexing analogue components of a TV signal to provide high-definition analogue television for satellite broadcasting).
And now back to our regular programme.....

On the UK local ensemble Coventry, an unlabelled "ghost" service that has persisted for several years has ceased. Recorded by multiple correspondents in multiple locations on multiple occasions and with various monitoring receiver types, this was likely an "orphaned" entry in FIG 0/17. Ash Elford recorded an explainer about this particular thing in 2024, which is still available on YouTube. This was probably the UK's, if not the world's, longest-running suspected mis-configuration. Anyone nostalgic for this state of affairs should retune to the Hereford-Worcs local ensemble.

On the UK local ensemble Hereford-Worcs, the Audio Components formerly associated with the services Capital UK, Heart UK and Smooth UK have ceased. Unlabelled services with the SIds of those services appear to persist in the FIC and continue to be listed on some receivers. The unlabelled remnants appear to retain their PTys - Pop Music, Pop Music and Easy Listening respectively.
