HD Radio multicast tuning (HD2 & HD3 channels)

[Sundancer213]

Now I Have internet Radio.

[xmaddict]

Is this your station? KYTI? Love the country music

[bratina501]

I might have to listen for those HD stations next time I get an E-skip opening to Wyoming. The system is actually quite robust which impresses me given some digital standards don't hold up well. Many AM and FM DXers such as myself all over the country have reported reception of HD through E-skip and other means. I have even heard HD Radio DX on the same frequencies as local FM stations, one of which being less than 20 miles away and running 100,000 watts!

[Sundancer213]

I brought this HD Radio on E bay the plug was loose. did anyone eles have this problem!

[sheridanmedia]

If you are referring to the type-F FM antenna input then I have the same problem. The FM antenna input on this model is not very secure and can be pulled loose. That happened to this one when it fell off of a shelf.

[jackwolf131]

AM sounds like FM. and FM sounds like i'm listening to my CD player

[sheridanmedia]

Yes, it is definitely the best sounding of all the digital radio broadcast systems. The compression artifacts on satellite radio are very noticeable to me even on the music channels. As long as the source material is good, FM HD Radio can sound almost as good as a CD. Unfortunately, many radio stations use audio files that have been converted to MP3, thereby reducing the sound quality before the audio even gets to the HD Radio encoder.

hey are they going too have built in hd radio on HDTV LCD's ???????

[fmbroadcast]

YES, HD Radio is the best digital broadcast because of it's caracteristic and powerful.

[Krellan]

Interesting how your classic country radio station isn't the HD2 of the mainstream country station. Instead, classic country is the HD2 of another, different, station.

That's different from the stations here in the SF Bay Area. Here, stations that have HD2 channels tend to be offshoots of their main HD1 formats. For example, classic country is HD2 of a modern country station, and 80's hit music is HD2 of a pop station. Unfortunately, I haven't noticed HD3 yet, on any of the stations here.

[sheridanmedia]

We did originally have the classic country on the HD2 of the country FM, but the formats were flipped when we started rebroadcasting one of the HD channels on an analog translator. The formats have been moved around again and I have just posted a new video with the current channel lineup

[jasonhdvideoman]

how am sound

[sheridanmedia]

HD Radio is commonly described as making AM sound like FM and making FM sound like CD. I think this is an accurate way to describe it. It definitely has less audible compression than satellite radio, and is much cleaner and clearer than analog radio.

[newbigvideofan]

This is an excellent system and I wish it was used here in the UK. Far more better than DRM IMO which is used on SW and some AM stations

[Lachlant1984]

Could you please describe what DRM IMO is and what it does?

[sheridanmedia]

Digital Radio Mondiale is basically the European counterpart to AM HD Radio in the US. While not identical, the two systems are very similar and have most of the same pros and cons.

[AIVMS]

There is a system called HD RadioPC that interfaces a relatively cheap HD Radio reciever to a PC.

You can actually set it to auto record the individual songs to mp3. Leave it going for a day and you have quite a collection.

They have a usb version of the interface.

[blackandblue10]

I heard the ending of "Du Hast" by Rammstein on 94.9 HD 2 :D

[achavez78]

Is there REALLY a difference between HD and regular radio? I mean REALLY?

[jamesbooty]

From a technology standpoint the difference is night/day. Because it is digital it isn't limited to just transmitting sound. Images could be transmitted as well as more text than is possible with analog RDS, and 5.1 surround is also possible. Sound is a subjective thing (some still prefer vinyl to CDs), but I think HD sounds better than analog FM & considerably better than XM. Plus with HD you get up to 3x as many stations as you do with analog so I'd say there is a considerable difference

[DStroyerPA]

Congratulations on using the technology the way it was meant to be used, with the HD-2's and HD-3's. There are way too many stations that just throw on the one channel, and then stop there.

[MississaugaKid]

Oh god! I cant stand country music.

[intoodeep0606]

The same way you hate country music I hate the urban r&b and reggaeton formats that I have to live with where I live. I would like to hear a station that has alternative 80s, Italo/Hi-NRG or bands from Australia (Models, anyone?). Maybe with HD or something better than that I would have a chance. Right now, my only option is Internet radio. I hope I don't have to pay a subscription to listen to good radio.

Oh, and portability is a plus.

[jkeelsnc]

I should have said 9 channels where there were only 3 before. In larger markets that have 20-30 radio stations will easily have 40-90 channels depending on how many subchannels they use.

[jkeelsnc]

This stuff is cool. I want an HD radio and there are several stations I should be able to get in HD (most of the stations received where I live are from the Charlotte market). The thing holding me back from an HD radio at the moment is the cost. Maybe at a later point I will get one. 9 channels of variety where there were none before! That is amazing and cool stuff like Air America and ESPN Radio. This could really help the commercial radio stations compete with satellite radio!

[vwestlife]

Sound like your analog and digital audio is not in sync. That is the most annoying thing to me when listening to FM HD Radio!

[sheridanmedia]

The timing issues have been resolved and in the new video I uploaded today you will not hear the audio jump when the radio switches from analog to digital.

[coondogtheman1234]

would it be possible to connect an HD radio receiver to a pc and record the digital bitstream from the transmission and save it as individual mp3 files like 1 file per song. i mean like a digital link between the hd radio to the PC like via usb or something is this possible?

[ge0rge22]

i just searched in wiki. Peace

[ge0rge22]

the name "HD Radio" is simply iBiquity's brand for its digital radio technology, and does not stand for "Hybrid Digital" or "High Definition" such as HDTV does

[trosvig85]

Great video. I am just wondering, does HD Radio, does it stand for High Definition Radio?

[sheridanmedia]

It stands for Hybrid Digital Radio.

[jamesbooty]

"Hybrid Digital" is a commonly used definition and is an accurate description of our current implementation of the technology (with analog and digital carriers on the same channel, and even originating from the same transmitter in some cases). Officially though, "HD Radio" is just a brand name and isn't actually short for anything. -- Steve

[skinnyblinddude]

I know this is really off topic, but I'm sure I heard a second or two of Tom Lehrer's Masochism Tango! LOL! No station in this goober-pickin' town of Jacksonville Florida would play that classic. But seriously, the Boston Acoustic Receptor is one fine sounding radio!

[sheridanmedia]

You have a good ear! The Masochism Tango was on the JokeJoke channel when I tuned it in. I agree that for its size, the Recepter is a fine sounding unit. I was actually surprised that the sound was picked up so well on the camera because our T.O.C. is a pretty noisy room. -- Steve

[sheridanmedia]

IMO the quality of the HD-2 and HD-3 channels is equivalent to satellite radio. The HD-1 is technically not CD quality because it is still compressed, but it can be streamed at bit rates up to 96kbps, which with the HDC/SBR codec makes it very difficult to distinguish from a CD. Good source material is the key to achieving near CD quality on an HD-1 channel. Most stations use some form of MPEG compression in their music delivery systems and the HD can amplify those artifacts. - Steve

[djscanman]

Nice demonstration. But, I have to take exception to the statement that HD Radio is "CD quality". I am a fan of HD and own two receivers (The Boston unit used in the video, and the SONY XDR-S3HD), and can say first hand it is NOT CD-quality (especially on the HD-2 and beyond channels).

[djscanman]

Sorry Steve, I'm a fan of HD Radio and own two receivers, and can tell you first hand it is NOT CD quality (especially on HD-2 and beyond channels.

It looks like 93.7 HD-2 (Real Oldies) is the channel I'd be spending most of my time with. 8)

The Boston Recepter is a nice radio (I have one), but the SONY XDR-S3HD (I have one of those as well), is better feature-wise and reception-wise, although the Boston has slightly better audio reproduction quality.
