WHAT IS SOFTWARE DEFINED RADIO (SDR)?
In traditional hardware radios, the mathematical operations required to decode and process radio signals are performed using analogue circuitry. Recently, computers have become powerful enough to perform the required mathematical calculations in software, hence the term software defined radio. This has led to advanced radios that previously required complicated analogue hardware now being able to be implemented easily in software. This has reduced the cost of advanced radio capabilities such as wideband tuning and waterfall displays.
WHAT IS THE RTL-SDR?
The RTL-SDR is an extremely cheap software defined radio which is based on DVB-T TV (Digital HD TV) USB receiver dongles that have the RTL2832U chip in them. It was discovered by hardware hacker Eric Fry, Linux driver developer Antti Palosaari and the Osmocom team who were developing their own SDR that the RTL2832U chip had a mode which enabled SDR. Today, by using custom software drivers, a commonly used cheap RTL2832U can then be turned into a sophisticated SDR with features that would have until recently cost in the hundreds to thousands of dollars. Of course, the performance of these dongles will not match a dedicated SDR, but they perform extremely well for the price, and almost all hobbyist projects that can be done with expensive radios or SDRs can also be done with the rtl-sdr. A wideband SDR opens up many interesting possible projects and avenues to explore. Some applications of the RTL-SDR include the following, some of which will be discussed in more depth in the project tutorials chapter.
Listening to unencrypted Police/Ambulance/Fire/EMS conversations.
Listening to aircraft traffic control conversations.
Tracking aircraft positions like a radar with ADS-B decoding.
Decoding aircraft ACARS short messages.
Scanning trunking radio conversations.
Decoding unencrypted digital voice transmissions.
Tracking maritime boat positions like a radar with AIS decoding.
Decoding POCSAG/FLEX pager traffic.
Scanning for cordless phones and baby monitors.
Tracking and receiving meteorological agency launched weather balloon data.
Tracking your own self launched high altitude balloon for payload recovery.
Receiving wireless temperature sensors and wireless power meter sensors.
Listening to VHF amateur radio.
Decoding ham radio APRS packets.

Listening to satellites and the ISS.
Listening to unencrypted military communications.
Monitoring meteor scatter.
Listening to FM radio, and decoding RDS information.
Listening to DAB broadcast radio.
Use rtl-sdr as a panadapter for your traditional hardware radio.
Decoding taxi mobile data terminal signals.
Use rtl-sdr as a true random number generator.
Listening to amateur radio hams on SSB with LSB/USB modulation.
Decoding digital amateur radio ham communications such as CW/PSK/RTTY/SSTV.
Receiving HF weatherfax.
Receiving digital radio monodiale shortwave radio (DRM).
Listening to international shortwave radio.
Looking for RADAR signals like over the horizon (OTH) radar, and HAARP signals.
In the software options, please use the program of SDR # with RTL configured to direct sampling of the signal Q, as shown in the following picture, so that the radio can work in Ham Bands
