I wonder if you worked out what Tom was actually doing? Not all the snippets in the recording are actually HD. Take the first two, Tom first tuned to 1050KHZ. As people in Southern California will know, KNX is on 1070KHZ so Tom tuned to 1050KHZ to force the radio into Analogue AM mode. Then he tunes to 1070KHZ where the HD encoder locks in. Later he tunes to KFI and we’re not sure if KFI broadcasts in HD or not. I’ve been reading a lot about HD Radio and - if the articles I’m reading are anything to believed - there may come a day in the USA when Analogue broadcasting is dropped completely and a new form of HD takes over? This scenario makes sense in many ways and of course - by that time - HD radio sets will be common place. They’re becoming increasingly common now though the public is blissfuly unaware of this and there’s probably no need to make a big issue of it. For example, the chip manufacturer Silicon Labs make a chip which is capable of receiving just about every radio mode one can think of, AM, FM, DAB+ and HD are listed in the specs. This chip has been available to automative manufacturers for quite some time and I’ve often suspected that Sangean might very well be using something similar in their radio sets.
