wi-fi, bluetooth, etc.) could do this, as long as one of the chips also has an SDR mode like the Realtek. It doesn’t matter that it’s a TV device, in theory any RF device (e.g. The key was actually the Realtek demodulator chip having a special SDR mode. A lot of people seem to be assuming anything that can receive TV can be converted into an SDR, as if TV reception was the magic key enabling this. PS: Reported rapid tuning issue may still exist (only happens for me if sample rates are not set correctly in a flowgraph), so take the tuning easy until a good fix is found :) Updates to the Windows plugin will arrive very soon! To make sure this device actually works properly, I successfully tested it with OP25 by having it capture an encrypted P25 signal, which was then decrypted/decoded and sent to the soundcard.Ĭheck it out (along with notes about new code): The Source block now makes use of new C++ ‘librtl2832++’ OO API, which can be pulled out and used separately for easy device control! Custom devices can easily be added in GRC block using ‘Custom USB’ parameters.
HOW DO TV TUNER FOR PC WORK CODE
I have just released completely re-written GNU Radio code with new GRC Source block, addition of FC0012 and support for all devices in compatibility table (those with E4000/FC0012/FC0013). Thank you to all of you who have tested the code so far and provided feedback! Posted in Radio Hacks Tagged ham, radio, sdr, software-defined radio Post navigation You can watch testing out his $20 GNU Radio rig after the break. The sample depth is 8 bits and the sample rate can be anything up to 3.2 MHz. With his source block, can listen to anything on the radio between 64-1700 MHz. The cheapest (so far, and subject to change) is the Unikoo UK001T available for $11 on eBay.

There’s an awesome compatibility chart listing compatible USB dongles.
HOW DO TV TUNER FOR PC WORK SOFTWARE
If you’ve ever thought about trying out software-defined radio, now might be the time.Įlsewhere on the Internet, a surprisingly active RTL-SDR subreddit popped up dedicated to using the Realtek RTL2832U tuner for software defined radio. With ’s work, anyone can use a cheap tv tuner dongle with HDSDR, Winrad, or GNU Radio. At the time, these capture cards could only write data directly to a file.

’s code comes just a week after hackaday and other outlets posted stories about using a $20 USB TV capture dongle for software defined radio. Now with a cheap USB TV tuner card, you can jump right into the world of software-defined radio. Just sent in a small yet timely project he’s been working on: a software radio source block for the Realtek RTL2832U.
