Script de instalare SDRPlay

Script pentru instalarea tuturor pachetelor necesare pentru utilizarea SDRPlay pe Raspberry Pi. Acest script se găsește și pe github la adresa https://github.com/yo3iti/Dual-SDR-install.git

Este foarte important să se instaleze înainte driverele oficiale pentru SDRPlay.
