HD Radio FAQ

Below are answers to some of the most frequently asked questions about high-definition (HD) radio.


What is the difference between HD and satellite radio?

HD radio is "terrestrial," meaning it is transmitted from a station to towers on the ground to radios within a localized broadcast radius. Satellite radio is transmitted from a station to a low-orbiting satellite to radios within a much-wider broadcast radius. Satellite radio currently offers little or no local broadcasting.

When will WRTI be broadcasting in HD?

It already is. WRTI has been broadcasting in HD in Philadelphia, Dover, and Harrisburg since the summer of 2005. Other areas are soon to follow.

Will I need to buy a new radio to hear it?

Yes. To hear WRTI's dual broadcasting with CD-quality sound, listeners must have a radio that can receive digital broadcast signals and has "multicast" capability.

When will WRTI play 24 hours of both classical music and jazz?

We are. WRTI listeners in listening on 90.1 in Philadelphia can hear classical music all day and jazz all night on WRTI-1 and jazz all day and classical all night on WRTI-2.

Why and when will traditional FM disappear?

Traditional FM isn't going anywhere, at least not in the near future. And, if you choose not to get an HD radio, you will still be able to listen to WRTI on your radio.

Is HD radio available where I live?

HD  is only available in Philadelphia, Harrisburg, and Dover, Delaware right now. Each transmitter is costly so it will take time for us offer HD in other regions.

Can I hear both streams on my computer?

Yes. We have increased our online streaming capacity, which means more people can listen to the music they want when they want it.

Can I hear stations that aren't broadcast in HD on an HD radio?

Yes. HD radios receive traditional analog broadcasts from stations that have yet to convert, and digital broadcasts from stations that have converted. Similarly, analog radios will continue to receive the analog portion of the HD broadcast, allowing for a smooth transition to a digital world.
