SDR-J Updated to Version 0.98

The RTL-SDR compatible DAB Radio receiving software SDR-J has recently been updated to version 0.98. DAB stands for digital audio broadcasting and is a type of digital radio signal used in some countries for transmitting broadcast radio stations in digital audio.

The new versions fixes some minor errors, brings back their ‘spectrum viewer’ software and also comes with a ‘DAB mini’ receiver which is simply a smaller windowed version of the regular DAB receiver. The new version also now supports the sdrplay and Airspy software defined radios.
