Gqrx receiving broadcast FM using RTL-SDR and Funcube Dongle

Gqrx receiving broadcast FM using RTL-SDR and Funcube DongleA short demo video showing reception of wide band broadcast FM using Gqrx SDR and comparing the Funcube Dongle (96 ksps) with an RTL2832U-based DVB-T dongle (running at 900+ ksps). The video also demonstrates switching between two input sources at run time. Gqrx is an open source software defined radio receiver powered by GNU Radio and Qt, read more at: Source
