97.1 FM The Drive-WDRV-FM Chicago-is one of the first stations in the world broadcasting
in (HD) digital radio technology with near CD quality sound-twice the fidelity of satellite
radio-and still free. All you need is an HD compatible receiver to start enjoying the
increased fidelity and reception. Plus, HD allows radio stations the ability to offer a second
digital program through multicasting. The Drive's Deep Tracks is now available on our HD2 signal
on both 97.1 and 96.9 FM.
How does it work?
The Drive bundles our traditional analog and new digital audio signal together on the same
frequency 97.1 FM & 96.9 to serve both traditional analog radios and new HD receivers, whichever
tuner you have will automatically discern which signal to use.
Increased Fidelity equals near CD-quality sound . . .
Digital technology allows a radio station to transmit more data in the same amount of bandwidth.
Primarily, this means higher quality sound, but there are other benefits too, such as our multicast
signal offering Deep Tracks Internet programming in rich, full hi-fidelity sound.
Digital also means improved reception . . .
The digital signal is less vulnerable to reception problems. The radio tuner's digital processors
eliminate the static, pops, hisses, and fades sometimes present in analog signals caused by
interference. Multipath distortion, caused by the radio signal being reflected off of buildings
and other surrounding obstructions, is completely removed. With HD digital radio you hear only
clear, clean, rich sound.
Should you lose the digital signal for some reason (obstructing terrain, nearing the edge of the
broadcast area, etc.), HD Radio technology defaults back to analog mode, similar to the way current
radios switch from stereo to mono mode when receiving a weak signal.
How Much do HD compatible Receivers cost and where can I buyone?
Prices vary depending on features and between manufacturers and will come down as more manufacturers bring HD
products to market. To get the latest information on tuners and costs visit
