Incroyable! You've nailed the second sound as Eurosignal paging, and you were bang on. After more than a decade, I finally know what it is. It's eery to hear almost the exact same sound emanating from speakers after all these years... Was my explanation that accurate or do you just have ninja Google abilities? I bought 10,000Hz Legend when it first came out, never even heard (or knew they released) an album called Premiers Symptomes. Crikey. Having just reached the end of Les Professionels, I've just realised everyone who ever uses the track only uses the portion which loops the ending guitar riff. Sadly I don't think the first sound is NAVTEX, I played the file back through decoding software (admittedly a poor recording) but it just decoded nonsense characters even without Strict FEC enabled (see screengrab: http://chriswoods.co.uk/files/2011_07_21-frisnit_navtex_wrongsignal.png ) Also the spectral information wasn't focused in the correct band. I may try and tune in tonight though with the old Sanyo boombox radio I have, see if I can pick something up at midnight... Thanks for IDing the mystery FM audio though! - Sent via the backstage.bbc.co.uk discussion group. To unsubscribe, please visit http://backstage.bbc.co.uk/archives/2005/01/mailing_list.html.
