Depending on where you live and where you travel, reception may be difficult or even impossible. The big advantage for Classical music listeners.Ĭlassical 89.7 has a relatively weak signal. Due to the digital nature of HD radio, the receiver corrects for multi-path so you can drive almost anywhere with no interruption of the sound. Multi-path is caused when your radio receives both a direct FM signal from the transmitter, and indirect signals that bounce off of tall buildings before they get to your radio. That's when you're driving down the street and as you pass certain locations next to tall buildings you hear a tick-tick, or picketing of the sound. More noticeable is the fact that HD radio virtually eliminates 'multi-path'. It has a wider frequency response (lower lows and higher highs) with no background noise (hiss). The quality of the HD signal is better than FM. Since Nevada Public Radio has two analog radio stations in Las Vegas (KNPR and KCNV), we have the capability to program 6 HD stations. There are additional HD stations (HD2 and HD3) on the same frequency. So News 88.9 is heard as an analog signal (FM) and as a digital signal (HD1). The first HD station (HD1) is exactly the same as the analog station. Using digital technology, one transmitter can send a digital signal for 3 stations. HD Radio technology allows radio stations to continue to broadcast the good old analog FM signal (for example, KNPR is 88.9), while using the same bandwidth on the assigned frequency to broadcast digital radio.Ī wider variety of programming is available with HD.
