TECKEEN Case Antenna 100KHz 1.7GHz UV HF RTL SDR USB Tuner Receiver R820T2 8232 AM FM CW
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.
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.
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.
