RTL-SDR.com SDR Dongle Giveaway!

We are giving away 20 of our new units with the metal case!

Competition has now ended! Thanks to all who entered! Winners to be announced by Monday.

The RTL-SDR and SDR community spans multiple disciplines and there are many wildly different projects being worked on by SDR enthusiasts as regular readers of our blog may already know. We want to thank all our readers with a competition and at the same time get everyone to share what projects you are all working on.

There are four chances to enter the contest and you may enter in all four competitions. On each method we will give away 5 RTL-SDR blog dongle + antenna units. Competition ends in one week on the 22nd of January at 23:59 hrs (midnight) PST time. Winners will be notified in the following 1-2 days and we will do a post about it too.

Competition Entry 1) Like us on Facebook and make a comment on the the contest post mentioning what SDR related projects you are currently working on, or plan to work on in the future.

Competition Entry 2) Follow us on Twitter and tweet at us @rtlsdrblog mentioning the SDR related projects you are currently working on, or plan to work on in the future.

Competition Entry 3) Make a comment on this very blog post mentioning what SDR related projects you are currently working on, or plan to work on in the future. (Please include a contact email address in the email field – it will only be visible to us and we won’t use it for anything else, promise!)

Competition Entry 4) Sign up to our email mailing list here or on the right hand navigation menu. (we send out a once weekly digest of the weeks posts).


We want to hear about any and all projects, no matter how simple you might think they are! At the end of the competition we will randomly select five winners from each competition entry method and contact them. Please remember to check your Facebook/Twitter/email accounts if your name comes up when the winners are announced.

Rules: Only one entry per person per method! E.g. you can enter once on Facebook, once on Twitter, once by commenting here, and once by signing up to our mailing list. No duplicate accounts are allowed. You must be legally be allowed to receive and own an RTL-SDR dongle to enter.

Hoping to set up a dedicated dongle to stream/decode some DMR & NXDN frequencies in my area…


Currently monitoring Inmarsat using homebrew patch antenna. Would use extra dongle for trunk tracking.


Now i am building a QFH antenna for NOAA satellites.


Taking my first steps into the world of SDR. Getting FM radio was easy, next up is DAB.
Thanks to the rtl-sdr team for providing so many guides!


Will use RTL-SDR dongle for learning wide band signals and monitoring Ham radio bands.

DWANGO Unchained

I have a large satellite dish which I plan on replacing the feedhorn on – looking to use the dongle to interpret the signal I pick up.

Sean Greer

I would like to visually monitor frequencies along the spectrum so that I am only adding active frequencies to my mobile ham radio and scanner.


Using it to receive ADS-B & contribute to @flightradar24, my old sticks are buggy, the crash every day.

Kevin McCormick

Dongle looks great. Keep up the great work.

Nate Stiller

What COULDN’T I use this for? I’ve been wanting one for some time now but I didn’t realize there are so many different possibilities just from reading the comments here! I would love to get my feet wet with one and dive right in to it all!

Kathryn Rosie

I’d like to build an AIS receiver for MarineTraffic.com. My dad’s retirement has consisted of kitting out an old trawler and using it as a workhorse up a remote coast, where there aren’t any AIS receivers currently. So initially I’d try build a mobile AIS station with a “backpack-mounted” dongle system, to find the best signal spots along his route, and then work on getting more permanent stations set up on those, so I can keep an eye on the old man!


I will use a dongle to receive NOAA APT transmissions and also to monitor local P25 radio


I’m working on a battery powered mobile unit using a CHIP computer for discovery and trunking.

Heath Raftery

Successfully reverse engineered some 433MHz temperature sensors to sniff the data with a Ninja Block for charting on our home status display. Looking forward to doing similar with some RFID gear by adding a downconverter.

Guy Vachon

Will be using the dongle in pair with the local svxlink/Echolink node I’m managing here in Quebec city Canada (Node VE2RIG-R #39339 on the Pierre Laporte Bridge) to extend it’s receiving capabilities. Another dongle will be used with a Raspberry Pi to receive the sgnal from the local Club repeater and stream it to Radioreference/Broadcastify. THis will surely help to let people hear what’s going on locally, and posibly bring more people in in this wonderful hobby. 73s from Guy VE2VAG in Quebec city Canada


Currently working on FM radio recognition system (shazam like, but in real-time for more than 30 radio stations). Multi RTL-SDR solution with dozens of dongles, separate receivers and server-part to collect stats etc.


Using RTL-SDR to receive ADS-B & contribute to @flightradar24. Hoping to simulate wirless roomstat next http://goo.gl/m8ljHd

Other than NOAA pics i’ve been planning for this weekend (January 16) ISS SSTV and upcoming similar events… I’ll be downloading the SSTV this time with a RTL and the same setup for NOAA.. if this works i’ll use it for future events while I go outside and try to contact the astrinauts with an HT and yagi antenna… I want to make reception automatic…


I would like to stream shortware and NOAA weather radio using something compact, like a Raspberry Pi. Thanks for this contest.


I have an ads-b decoder running all the time and would like another dongle so I can experiment with a web-SDR server.

Prof. Sean Hum

I’m introducing SDR kits in my 4th year university course on microwave and wireless systems. Though not based on RTL-SDR, they use low-cost Softrocks so that students get a chance to build the radios from scratch. They get to learn about radio electronics, amateur radio, and browse the radio spectrum using an SDR with HDSDR, which should be a very fulfilling experience (introducing this as a new part of their lab experiments this year). http://tinyurl.com/z9c9b37


I’m trying to build a QFH antenna so I can try to recieve some NOAA signals. Will try with cubesats too.

Marty Wittrock

I’d be really interested to see the performance of the shielded assembly and how it works with my HF Upconverting and Direct Sampling HF SDRs that I make now and have had featured here on RTL-SDR.com

Matthew Lawson

Working on a ultra portable satellite antenna tracker with rig control and telemetry decoding.


Experiment airborne geolocalisation on a high-altitude baloon by triangulation of terrestrial signals in multiple bands (e.g. APRS digipeaters, FM RDS, ham beacons, GSM towers, etc).

Stan F

Working on portable ASD-B for car use.

Dan Renner

I’m aiming to make a cheap RasPi2-based radio scanner to listen to a Motorola SmartZone II statewide system!


Currently working on creating a portable station for use with RTL-SDR dongles as well as decoding MAVLink messages.


Streaming a private DMR and NXDN feed with DSD+


Portable rf spectrum analysis


Hey Jeff~
I was wondering what your setup was like. I was considering getting one of those MicroCenter Winbook TW700 because it runs windows and has a full size USB port and is pretty cheap. I tried SDR Touch on an old android tablet, but found it kind of limited.

Nuno Sousa

Next project receive airplane communications 🙂


This is pretty fascinating seeing all the different things people are doing with theirs. I (incorrectly) assumed everyone was doing typical police scanner type things. So many possibilities, and a great community too.


I’m doing P25 decoding and streaming, POCSAG pager decoding and various signal hunting things. Just got a raspberry pi 2, so who knows what’ll be next!

David Stark

I want to build a portable all-mode (or as near as possible) digital decoder and trunktracker around an SDR and a Raspberry Pi and/or Arduino.

Dale Robins de 2W0ODS

I aim to build a portable device that everyone can use, using off the shelf parts for a SDR2Go, a Display, Power controller/battery, for SDR Anywhere 🙂


I’m using RTL-SDR in a project for developing a proof-of-concept ISDB-T 1 seg (digital televison, low bandwidth) decoder.


Using RTL-SDR with gnuradio and gnss-sdr to decode GPS

Dave H

Developing efficient PSK and/or WSPR beacon transmitters for high altitude balloons, and I need an inexpensive spectrum analyzer to measure bandwidth and spurious outputs.


I’m working on building a WebSDR in Bucharest with full coverage from ~15mhz to ~1700mhz (R820T2 upper limit)
