If you'd like to purchase a radio in a store, or test it out before you buy, we have partnered with The Sound Room in Chesterfield. They regularly stock tabletop HD radios and they will give a portion of the proceeds of their sale to the station when you mention that you heard about them through us. We have found that the large chain electronics stores in St. Louis do not regularly stock tabletop HD radios. Many St. Louis-area vendors do carry HD radios for automobiles.
No matter where you get your HD Radio, please give this exciting new technology a listen. You’ll never listen to radio the same way again!
HD radios sound better
Regular FM radio has the ability to produce high-fidelity sound under the right reception conditions. FM frequencies require a line-of-site path between the FM transmitter and the receiver. Hisses, pops, static, and fading occur because FM signals are reflected from obstructions such as buildings—or from you when you move around the room where your radio is located.
HD radio differs by using digital technology. This technology minimizes reception problems and offers freedom from the interferences described above. Also, digital technology allows stations like St. Louis Public Radio to squeeze in additional services, thanks to cutting-edge compression technology.
HD radios receive more stations than FM radios
Several years ago, St. Louis Public Radio installed the equipment necessary to broadcast digital signals, in addition to our regular analog signal. Essentially, this allows us to have two signals in the "space" it takes for one. On your HD radio, these three channels are still found at 90.7 on the dial.
Installing a new radio seems daunting to some; others like their current factory-installed radios. Professional installers at stores like Hi-Fi Fo Fum or Best Buy can complete a professional installation of an "after-market" radio, such as an HD radio from Pioneer, in a couple of hours. Templates are available for most car models so the finished installation makes the new HD radio look like it was factory-installed.
