    Ruling Delayed at FCC Meeting today....though probably not for long

    DXing is still a valuable hobby. Plus, putting IBAC (I call it that because destroying adjacent channels doesn't count as "on-channel" to me) on AM stations at night can potentially cause inteference problems for local listeners. Remember what I said about the Canadian government formally...

    Ruling Delayed at FCC Meeting today....though probably not for long

    It depends where you are - in a high-rise apartment building you may certainly experience severe noise, but manmade noise at my rural location is very low. This also holds true for my aunt's house in a small town. It all varies. As for clear channels, many have been undermined by having...

    Ruling Delayed at FCC Meeting today....though probably not for long

    AM "HD" radio would be a disaster, plain and simple. It would almost destroy a legitimate, enjoyable, and worthy hobby, all so Ibiquity can collect royalties and stations can broadcast to a small audience with improved audio (really not that important). FM HD 24/7 has been enough of a problem...

    Once you hear HD)) AM Or FM You will never go back to normal AM/FM

    If you want to see an example of the ill effects of IBOC, look at this bandscan: http://pages.cthome.net/fmdx/fmscan.html And compare it to one archived from just five years ago: http://web.archive.org/web/20010616201433/http://pages.cthome.net/fmdx/fmscan.html Much of his dial has went from...

    I don't anticipate an analog shut-off until at least 2020. That's my guess. The big difference between TV and radio is that most TV's today are connected to some external source (cable or satellite), while radio tuners are virtually always not.

    Simply inventing a system does not entitle one to have it become the mandated national standard. That is unfortunate that they chose a closed standard. Although many TV stations also transmit MPEG audio streams. It's undeniable that we are moving into a digital future....but let's hope...

    Please read what I wrote about making an open-source decoder or encoder for an example. These are nearly impossible to license as they are distributed freely. A similar scenario has occurred in the last few years with the owner of the MP3 patents demanding royalties, hence the (accelerated?)...

    Once you hear HD)) AM Or FM You will never go back to normal AM/FM

    Whether the licensing fee is small or large is not the matter....it's simply the fact that a corporation owns the system. And DBX is optional (I don't think AC-3 is though; perhaps a bad part on the FCC's side for choosing that system). HD Radio is the entire system. What if somebody wants to...

    Once you hear HD)) AM Or FM You will never go back to normal AM/FM

    Exactly...that's part of why I think HD Radio is a bad idea. As we move more and more into a digital future, do we want to do so in a fashion that favors open systems and competition, with consumer systems that are able to perform their task with the greatest flexibility, or one that favors...

    It may be acceptable by the law, but what about to the normal consumer who wants to listen to his or her radio station? My hometown presents a good example - we have two station, one on 94.1, and the other at a somewhat longer distance of 93.9. With good tuning and a decent antenna or...

    200 kHz?! That would wipe out a huge percentage of the entire AM band. I think you meant 20 kHz. And FMs? It does interfere with adjacent-channel FMs. In my area, whatever pops up from time to time on 91.5 and 91.1 are wiped out by strong digital noise (a sort of artificial static...

    Once you hear HD)) AM Or FM You will never go back to normal AM/FM

    I'm very nervous about HD Radio. It may sound good at a demonstration, but once they do "multicasting" (the current trend) at the rate of 2 or 3 channels per frequency, the quality drops greatly. My main concern, however, is how badly it impinges on adjacent frequencies. FM DX'ers living...
