["Description:\nWHAT IS SOFTWARE DEFINED RADIO (SDR)?\nIn 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.\n\nWHAT IS THE ?\nThe is an extremely cheap software defined radio which is based on DVB-T TV (Digital for HD TV) USB receiver dongles that have the RTL2832U chip in them. It was discovered by hardware 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. A wideband SDR opens up many interesting possible projects and avenues to explore. Some applications of the include the following, some of which will be discussed in more depth in the project tutorials chapter.\n\nFunctions:\nListening to unencrypted for Police/Ambulance/Fire/EMS conversations.\nListening to aircraft traffic control conversations.\nTracking aircraft positions like a for radar with ADS-B decoding.\nDecoding aircraft ACARS short messages.\nScanning trunking radio conversations.\nDecoding unencrypted digital voice transmissions.\nTracking maritime boat positions like a for radar with AIS decoding.\nDecoding POCSAG/FLEX pager traffic.\nScanning for cordless phones and baby monitors.\nTracking and receiving meteorological agency launched weather balloon data.\nTracking your own self launched high altitude balloon for payload recovery.\nReceiving wireless temperature sensors and wireless power meter sensors.\nListening to VHF amateur radio.\nDecoding ham radio APRS packets.\nWatching analogue broadcast TV.\nSniffing GSM signals.\nUsing on your Android device as a portable radio scanner.\nReceiving GPS signals and decoding them.\nUsing as a spectrum analyzer.\nReceiving NOAA weather satellite images.\nListening to satellites and the ISS.\nListening to unencrypted military communications.\nRadio astronomy.\nMonitoring meteor scatter.\nListening to FM radio, and decoding RDS information.\nListening to DAB broadcast radio.\nUse as a panadapter for your traditional hardware radio.\nDecoding taxi mobile data terminal signals.\nUse as a true random number generator.\nListening to amateur radio hams on SSB with LSB/USB modulation.\nDecoding digital amateur radio ham communications such as CW/PSK/RTTY/SSTV.\nReceiving HF weatherfax.\nReceiving digital radio monodiale shortwave radio (DRM).\nListening to international shortwave radio.\nLooking for RADAR signals like over the horizon (OTH) for radar, and HAARP signals.\n\nSpecifications:\nSize: 8.5x5cm/3.35x1.97\"\nQuantity: 1 Set\nNote:\nPlease allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid\nDue to the difference between different monitors, the picture may not reflect the actual color of the item.
