Pocket Radio -tyvm- for the Crack-Pipe Answer. Heard my 1st AM/MW "HD" Radio Broadcast - Today 6 OCT 2007 http://groups.google.com/group/hd-ra...206109df86f5a0 http://groups.google.com/group/hd-ra...ae20cc0e4e0fb7 Actually the distance was about 55~60 Miles and it was the 1st AM/MW "HD" Radio that I have been able to Hear up here in Twain Harte, CA. Again the Stereo {Bumper} Music sounded OK -but- the Talk Radio Hosts and the Fox News Readers voices all sounded thin and tinny with an echo. I assume that this was due to the KFIV 1360 kHz Radio Station's Audio Processing or may be the Fringe Area reception characteristics of IBOC -idk- In general the few FM "HD" Radio Station's Music Sound and Voice Quality that I have heard has been 'as good' or 'better' than the Analog FM Radio in Stereo up here in the Foothills; that I can get from the California Central Valley Cities around 60~90 Miles away. Currently using a Vertical Rectangle Loop Antenna that is about 6-Feet High by 24-Feet Long (60-Feet Around) with a Coax Cable feed-in-line. Pointed at Modesto, CA. Plus a Radi-Osophy HD-100 Radio. hy dee ray dee oh ~ RHF Hello and Welcome to the "HD Radio" NewsGroup HD RADIO =http://groups.google.com/group/hd-radio/ . - Stereo ? David, { Yes I Did Say "Stereo" } Yes it is my understanding that the iBiquity IBOC's Hybrid AM/MW "HD" Radio's Digital Side Bands do provide Stereo Sound to AM/MW "HD" Radio Listeners. http://en.wikipedia.org/wiki/HD_Radio About iBiquity HD Radio = http://meduci.com/ . Each AM Radio Station is allowed to transmit one Stereo Digital Channel, and cannot stream multiple channels, as in the case of FM HD Radio. About IBOC = http://en.wikipedia.org/wiki/In-band_on-channel . It is based on the Principle of AM Stereo where it puts a Digital Signal where the C-QUAM System would put the Analog Stereo Decoding Information. Foti on AM HD Radio: 'No Static at All' {and Stereo} Radio World OnLine -by- Frank Foti http://www.rwonline.com/reference-ro...d_foti_1.shtml * With the rollout of AM HD Radio, the senior band not only offers no static at all, but Wide Frequency Response that is equal to FM, and - ready for this? - Stereo! * It's still a bit surreal to realize that the Audio Signal emanating from an AM "HD" Radio contains 15 kHz Audio response, Stereophonic Sound, low noise floor .... and ... no static at all! HD Radio Ready for Prime Time Radio World OnLine -by- Glen Clark . http://www.radioworld.com/reference-...d_glen_2.shtml * AM HD is stereo (in "enhanced" mode). * I found that the AM "HD" Radio System usually stayed in Stereo Mode when the daytime signal strength was more than 5 mV/m, AM/MW "HD" Radio is 'by-design' Engineered to provide a Pair of {Left and Right} Primary Digital Side-Bands and that these Two Side-Band can be used to produce "Stereo" sound from a "HD" Radio that has a Two-Channel Audio Amplifier and a Pair of Speakers. http://electronicdesign.com/Files/29.../Figure_02.gif yes i did say 'stereo' - please corrrect me 'if' i am wrong ~ RHF |
