This was as I thought, Terry. In fact I informed someone with a Blaupunkt Radio that the ARI system was (a) Never used in the UK, abd (b) is obsolete, As to the BBC 'Carfax' system, I remember that being trialled, althiough, IIRC, they used 557kHz for at least some of the test transmissions. This is of course within the MW (AM) Broadcast band, unlike 500kHz, so the decoders could have been incorporated in normal MW Radios, although Carfax was never put into regular use.
