However, they still have their uses and a place in the radio listeners hobby room. I have often been asked why most of the software for small SDR receivers does not include scanning receiver functions. I have always pointed to the difference in vision: Namely the panadapter display. A ...
Hardware radios with discriminator taps connected to a PC may also work. Examples of DSD Decoding Digital Voice with RTL-SDR as a Radio Scanner YouTube user Geoff Wolf shows a video where he uses RTL-SDR as a police scanner to listen to public safety P25 digital radio using DSD, SDR...
Recently, I came across an interesting article on using software-defined radio (SDR) to create a Police, Fire, EMS, and Public Safety systems scanner. Viewing a few of these Trunk tracking scanners on Amazon, I quickly discovered that they are not cheap at all. You can spend several hund...
Thank you to Mike for writing in and sharing with us his video detailing how he makes use of a Raspberry Pi 5, touch LCD Screen and RTL-SDR to create a portable and low cost P25 police scanner. Mike notes that the cost of his system is $250, which is a lot cheaper than a compar...
Just like the police scanner project from April this makes use of RTL-SDR in the form of a TV tuner dongle. He uses the SDRSharp software along with a Yagi-UDA. The captured data is then decoded and plotted on a map using ShipPlotter. Posted in Radio HacksTagged ais, boat, RTL-SDR,...

There are several amateur radio pseudo-doppler devices that use a standard scanner radio, for example the RDF42 and the DDF2020T. An open source implementation of Pseudo-Doppler is Opera Cake for the HackRF. TDoA:Time Difference of Arrival (TDoA) methods require multiple time synchronized radio...
Since the RTL-SDR dongles are meant to receive high power wide bandwidth TV signals, they are not as as sensitive or frequency stable as a ham radio or scanner. Receiver performance will be a little less than an equivalent radio performing the same task but depends on the usual variables: ...
Economic and intellectual obscurity. The knowledge to build a “real” radio has been out there for years. What’s out there and how it works too. The tale of RTL-SDR is as much about free and easy to use software as it has been cheap hardware. ...
