Lets start by just listening to every-day FM radio. Open up SDRsharp.exe (you can close Zadig)
Begin by selecting the RTL-USB dongle instead of audio card
Select WFM (wide-band FM radio) under the Radio signal type
Click on Configure
And set the gain about half-way up
You can set your favorite frequency (FM station) by clicking on the large numbers up top
Click Play/Start and set the volume starting from low to high so you don't hurt your ears!
You can 'seek' for radio stations by looking for peaks. Click on them to tune in
With the latest versions of SDR-Sharp it will automatically detect and decode RBDS/RDS data that is sent along with FM radio
Chances are your radio station is also playing Donna Summer!
