Here is my latest weekend project; a Raspberry Pi 5 with an RTL-SDR dongle running SDRTrunk software. It is configured to listen to the local LAPD channels and runs great! The chip gets a bit hot so I think I need to add a fan. Building a $600 P25 Police Scanner for $250!!! (...
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...
Depending on the hardware used, its radio frequency coverage could span between 50 MHz and 2.2 GHz. Turn your mobile phone or tablet into an affordable and portable software defined radio scanner. SDR Touch currently demodulates WFM, AM, NFM, USB, LSB, DSB, CWU and CLW signals. ...
Triangulation of a VHF Signal with RTLSDR-Scanner A few months back we posted about how the theRTLSDR-Scannersoftware had been updated to include signal triangulation capabilities. Now blogger Tobby haswritten a post about his attempt at triangulating the source of an encrypted police signalwith ...
I used two RTL-SDR dongles to build a P25 trunking scanner, used to listen to shortwave, etc. But I'm also a licensed amateur radio operator who has worked all 7 continents, all 50 states, 80+ countries... Used to run a APRS digipeter, got a bitx40 kit collecting dust somewhere....

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 ...
