Sangean HDR-1 Tabletop Radio

The Sangean HDR-1 tabletop radio gives you everything you’d expect in an HD radio – AM sound as clear as today’s FM and FM as clear and clean as if you were listening to a CD. Thanks to my special price, it’s just about the most affordable, top-quality HD tabletop radio available and represents a great price value.

As you would expect, the Sangean HDR-1 tabletop radio lets you hear all those “invisible” HD2 channels between the regular frequencies – where broadcasters have put different and, in some cases, very non-conventional programming.

Plus, the Sangean HDR-1 tabletop radio displays text information, such as station IDs, artist names, and song titles on its large, easy-to-read LCD screen.

In addition, the Sangean HDR-1. has two 2-1/2″ speakers set in the acoustically tuned cabinet that deliver rich, detailed highs and mids, with nice, round bass. You’ll also like the sort of hip, retro look of its nicely finished wood cabinet.Letting the HDR-1 wake you up almost makes the morning fun with its built-in digital clock that displays both time and date, and includes dual alarms with snooze, as well as a sleep timer. Adjust the sound with the bass and treble control, or just use one of the EQ presets. And you can operate the radio from across the room with its provided remote.

Sangean’s suggested retail price of this tabletop radio is $249.95.
