Hardware
- rtl-sdr[1] - DVB Tunerkarte kostet 5-20e und hat sehr gut RTL2832U Empfängerchip. Beste Karte arbeitet mit 60-2200MHz, schlechte nur 100-1500MHz.
- Vergleich die besser Amateurradiolösungen auf Netz[2].

Software
- GNURadio[10] - gute Paket mit Python bibliothek. Kann mann zusammenbauen die Digitale Soundkompontente, and GNURadio-Companion[11] produziert ein Python Script.
- Octave[12] - mathematische Programmierungsprache.
