Greetings, I have absolutely no idea what system is being used in the files, DropBox link for which is below, all I can tell you it in the UK A.M stereo has never taken off, I am unaware what, if any serious experiments have been carried out over here.
The archive file, link for which is below, contains two .mp3s, one is a report given on the date indicated by the file name, the other, is a recording made of the A.M. stereo service named, in the location indicated,at the time and date specified in the file name. Please be aware the recordings, at a rather low sampling rate, are somewhat over-modulated but ought to give some idea. I know only what is in the recordings therefore cannot make any further comments. I will only leave this file on Dropbox until Thursday next, 2014/04/10 at mid day UK time, as I do not have much disk space left with which to work. File Name: A.
