HD Radio
Commercial radio beat us again...they are the first to come out with a
significant release of digital radio. Amateur radio's contribution is insignificant. I know, there are a few expensive rice boxes out there that use it but the Ibiquity commercial format is already present and in fact pervasive. Must be that darn old CW requirement that held us back again. I will say that the FM sure sounds fantastic on my Boston Acoustics Receptor HD Radio receiver. The multicasting feature of HD2 is a big step forward. I have one station in my area that does HD2 now but I understand the FCC license for this is still considered "experimental". No AM stations in my area use HD it and I understand AM commercial cannot use it at night because AM "HD" in this format takes up about 10 KHz so interference becomes a problem. Amateurs could probably come up with something at half that bandwidth using SSB, with a sound that is as good as existing mono FM. |

The ARRL did it... By the way, you've been a bit out of touch with digital radio broadcasting. Digital radio has been going on in HF bands for about 4 years now...doing what many olde-tymers said was "impossible." Then you've forgotten about the satellite downlinks for digital radio. LA |

Yeah, I'm aware of that, but it is rice box technology. I know of no hams that have made homebrew digital transmitters; you have to buy them from kenwood etc, thus the credit for the technology must be given to the commerical manufacturers with no contribution from amateur radio licensees other than for field testing it. Of course I never thought about satellite downlinks because so few of us use them. I know that what we do use is ancient technology compared to commercial compressed digital; we only transmit staellite in analog format and it is rather a waste of time/money. |

I don't enage in ethinc slurs as you hav e here i don't enage in inflamitory libel either A "rice box" is not characteristic of an ethnic slur. I am merely celebrating ethnic diversity, acknolwledging the superiority of their contributions to the amateur service when compared to those of, say, kb9rqz. |
