Re: Sangean HDT-20 AM/FM/HD Tuner

Dane and others,

I purchased one of these tuners a year or so ago and have been generally
happy with it. The reviewer mentions experimenting with antennas, and I
created a larger loop for AM reception and it added a good deal to the
sensitivity of the AM section of this tuner. However, I would agree with
the reviewer that the supplied loop does a better than average job for that
type of loop which is likely due to the tuner's sensitivity.

One of the reasons there is a lot of comment about audio quality is that one
cannot make any assumptions about how tuners work because of the
complexities of the circuits inside. For example, I also have a Teac HD
radio and have connected it to my stereo using the headphone jack. It has
great audio when the signal is strong and on HD signals. However, if an FM
analog signal is even of medium strength, that radio reduces the high
frequency response and does not have a stereo signal. It also seems to
reduce the low frequency response some. The Sangean does a pretty nice job
of maintaining frequency response, something I appreciate. I would rather
choose to lower the high frequencies if I found the noise to bother me.
However, the Sangean uses a very narrow FM bandwidth when stations are not
real strong. While selectivity is super and signal to noise is very good,
the analog audio is annoyingly distorted on signals that I believe would
still be very listenable with a wider bandwidth. This tuner seems to be
very resistant to the effects of overload from strong signals.

Since we have lost all of our AM HD stations in my area, I also don't
understand why the Sangean tuner doesn't allow a wider bandwidth to be used
on AM analog only signals. The Sangean tuner has a very nice extended low
end on AM, though. I appreciate that.

So my bit of frustration is that there are some artificial limits being
imposed by the engineers designing some of these tuners that I just don't
really understand. Still, I find the Sangean tuner to be very enjoyable on
HD signals and to be a good overall tuner.

Best regards,

Steve Jacobson

I know those in the USA are interested in HD radio as I would be myself if
we had those radio standards in Australia.

We don't so I can only be as envious as hell and wish I could move to the
States tomorrow <smile>

The following link is to a review of the Santean Hdt-20 AM/FM HD radio
component tuner.

I've read the review and the tuner is one of those things I'd very
definitely like to own and put to use in my lounge or on my Hi-Fi system in
the Den.

I would be most interested in comments from others.

I know there are people on list who own HD Radio sets, does anyone own the
Sony set which is mentioned in this review which seems to be held in very
high regard.

Anyway here's the link;data=02%7C01%7C%7C5b640d0a283
