RTL_ACARS Console Acars Decoder for RTL-SDR

On the Osmocom mailing list, Andreas has posted his work on a console based ACARS decoder for the RTL-SDR. Check out the mailing list thread here, and original post here. The second post on the thread shows how to compile it under Linux. Andreas writes

I have combined “rtl_fm” with Thierry Leconte’s (GPL’ed) acarsdec library code and created “rtl_acars” which can directly decode ACARS flight info messages to the console. Confirmed to compile on OSX 10.6 (not possible for me to check if it also compiles under Windows and *nix). Feel free to add it as another proof of concept to your distro unless you consider it too much of a quick&dirty hack.

Only the source code is available, and you will need to compile it yourself. The code can be found here.

Receiving a 10GHz Beacon with RTL-SDR and an Avenger LNBF

In this video YouTube user feri67000 shows reception of a 10 GHz amateur beacon over 26km using the RTL-SDR, and an ‘Avenger LNBF‘, which we believe is this one which only costs $11. The LNB within the Avenger antenna converts the 10 GHz signal into a frequency that is receivable by the R820T RTL-SDR.

Also, in this video by YouTube user EA5KGD reception of a voice signal is shown using the RTL-SDR and Avenger LNBF.

RTL-SDR SDRSharp Scanner Video Tutorial

If you’ve been having trouble figuring out the use of SDRSharp plugins, YouTube user radiosification has put up a useful video tutorial showing the installation steps required to get set up with the popular SDRSharp fast scanner plugin (old link), which was also recently updated.

In the second video he shows the fast scanner in action on the airband.

HackRF Decoding PICO High Altitude Balloons (HAB)

Blogger g0hww shows us how he used his HackRF to decode Pico high altitude balloon (HAB) transmissions using gqrx and dl-fldigi. Pico balloons are small party sized high altitude balloons, typically launched by hobbyists. They have enough lift to carry a small sized ~60g payload. Since they are so small, they are usually exempt from requiring permission from the authorities, unlike full sized weather balloons.

The cheaper RTL-SDR could also be used to track these balloons.

RTL-SDR as a Cheap Panadapter

For people already with expensive ham radios, the RTL-SDR can be used as a cheap panadapter. A panadapter is device that allows you to visually see the RF spectrum and waterfall being received by the ham radio. There are multiple (expensive) commercial panadapters available, but combined with a PC or laptop, the RTL-SDR will work just as well.

In this video YouTube user akdude47 shows a tutorial on setting up the RTL-SDR as a panadapter for a Yaesu FT-857. The setup involves connecting the IF output of the radio to the RTL-SDR, and putting in some settings into HDSDR.

How to setup a RTL SDR with HDSDR and a FT-857 for a panadapter and second receiver.
