The DRM Consortium has developed an online tool to quickly find DRM shortwave broadcasters, their transmission times and target areas. This tool is accessible for both DRM members and non-members and is illustrated in the following picture.

To use the map and the broadcast information, simply click on the circles which cover world regions where transmissions occur and where broadcasts are received.

After clicking those circles, the details of shortwave broadcasts to that region will appear in the table listing below the map.

There is no similar comprehensive list for mediumwave transmissions.

The nature of shortwave signals means that reception is often possible far outside the intended target areas.
