Intro to RTL-SDR Dallas Clements K7DCC

Agenda What is RTL-SDR? What can RTL-SDR do? How much does it cost? Software More information

What is RTL-SDR? Realtek Labs Software Defined Radio Term is a catchall for multiple designs built on the R820T and RTL2832U 4-5 years ago European TV tuners based on the RTL2832U chipset were found capable of accessing wide portions of the RF spectrum Most common RTL-SDRs receive 25MHz- 1750MHz Add on hardware available for MF and HF Very inexpensive

What can RTL-SDR do? Receive and decode radio signals cheaply using a personal computing device

What can RTL-SDR do? To learn more about these applications, visit Scan police, fire, ambulance, air traffic control, cordless phones, baby monitors, and FM radio Monitor and record amateur VHF and UHF frequencies Be an affordable spectrum analyzer Decode images from the ISS, APRS, PSK 31, and other digital modes Track aircraft and maritime vessels Direction finding

How much does it cost?

Software Windows: SDR# (aka SDR Sharp), HDSDR, SDR- Radio v2 OSX: GQRX Linux: GNU Radio Android: SDR Touch, OpenHPSDR
