 "Well conceived, well packaged receiver" 2009-10-17
By Mark E. Tomlonson
I am the Chief Engineer of a radio station that has just begun HD Multicasting. I purchased two of these units to use as studio monitors, one for each HD channel. The both fit on a rack shelf very nicely (There is no rack-mount provision). Set up of the units was simple, but not intuitive. They do run a bit warm, but not so much that it is a cause for concern. The price point was a selling point for me, and I would recommend them for anyone wishing to add HD capability to a home audio system.

 "Great FM tuner" 2009-10-17
By B. Wilson (Brooklyn, NY USA)
I found out about this device from a mention in a Ham radio publication, CQ-VHF, then I began to research it. I read reviews geared to Audiophiles, Ham radio operators, broadcast engineers and hackers. They all agreed it is a great tuner. They all say it is very sensitive has great sound and they are all in love with the HD performance. All saying it is better than a more expensive unit by Sangean. I agree with all the statements I've read about it's performance. Here is what I observe about the unit. Most people complain it runs hot, I disagree, it is a little warm but nothing out of the ordinary. They complain you cannot shut off the display when it is off, so what, I don't care, it doesn't bother me at all. It's said that the memory is lost very quickly when it is unplugged, I haven't tested that and I can mod the unit to fix that. The only other comment I've seen relates to its behavior with a weak signal and how it blends the channels to reduce noise. I haven't noticed anything in that regard.

Here is what I don't like about it. It doesn't come with batteries for the remote. I discovered this at 9PM and had to make a mad dash to the corner store for two AAA cells. I have a lot of AA cells but almost no one uses AAA cells. The remote will not change the volume, this is really annoying, no mute either. You cannot use the buttons on the remote for direct frequency entry. The photo of the unit is almost misleading, it is very small. It will almost hide behind a $100 bill.

HD is broadcast with a power level -20db from the main FM transmitter, that's 1% of the main carrier power. Understanding that you can see my concern about WQXR-FM in NYC going from a 6,000 Watt carrier on 96.3 MHz to a 600 Watt transmitter at 105.9 MHz. Thats a drop in HD power from 60 W down to 6 W. Imagine a 6 Watt light bulb on top of the Empire State Building! That is the power this tuner is dealing with. Yet, in North Brooklyn, using a roof TV antenna "temporarily" in my bedroom, HD reception is perfect. Forget the monthly fees of XM and Sirius, go HD. Buy this tuner.

 "How can something so cheap sound so good?" 2009-09-24
By Music Omnivore (Boston)
A superb, incredibly well priced tuner. Sensitivity and selectivity far better than even the best vintage units. The sound quality of the Sony will be bested (very slightly) by the very expensive vintage tuners on strong FM signals, but for most stations the Sony kicks butt sonically. I suggest the Brian Beezley modifications for even better sound.



Run, do not walk, and pick up one of these tuners. At this price, buy two. It's a no-brainer.

 "Sony HD radio turner" 2009-09-21
By John M. Allred
Unit worked as advertised. Was fairly easy to set up. There are lots of HD FM stations in the area, so lots to choose from. However, I really can not tell much (if any )difference between a good FM station and the same station in HD. Maybe it is my ears (but I don't think so). By the way, the unit is a good night light for the room that it is in. Thank goodness, it isn't in my bedroom.

 "Good HD radio tuner" 2009-09-12
By Eagle (South Florida)
My garage radio freaked out in one of our lightning storms and wouldn't tune to any radio stations anymore. Everything else worked fine, the external cd player, etc. I bought this and connected it to the auxillary input of my amplifier, and it worked great. The sound appears to add something that my original amp tuner didn't do. I get a more crisp sound. As an added bonus, I can receive a radio station, that is out of reach for the garage tuner as well as the tuner in my house that has an external antenea, that we always wanted to listen to. So I also bought one for the house. Overall, I think this was a good buy.
