Radio Listening Tips:

Location of your radio - if you're experiencing interference or static, try moving your radio or radio's antenna. Depending on your location, our signal could be obstructed by other buildings or the landscape. If you're further away from our radio signal, these obstructions (and environmental changes) can have a bigger impact. Moving your radio or antenna may help clarify our signal.
Time of day - if you're listening to one of our AM signals and it suddenly turns to static, it could be due to our operating requirements with the FCC. At sundown we reduce the power output from our AM signals in order to prevent interfering with other AM signals across the U.S. As the seasons change and days get longer/shorter, the time we reduce power can be earlier or later.
Quality of your radio can make a big difference - if you experience interference or static, try listening on a higher quality radio. If that resolves the interference/static issue, you may want to consider purchasing one or two to replace your current radios.

HD Listening:

In addition to analog radio, we broadcast programming on HD signals across the state. In general, HD offers a high-quality signal that may be distinct of the content on the primary signal. As an example, you could listen to News/Studio One on WOI 90.1 FM HD-1 and Classical on WOI 90.1 HD-2. You will need an HD radio receiver to listen to these signals. Here are two HD radio options:
