SDR videos

Software-defined radio (SDR) technology can be used for many interesting technical experiments. With listening only SDR you can do many interesting things, but having a SDR that can also transmit opens many new doors. Here are some interesting videos related to SDR and cyber security:

    Get Your Weather Images Straight From The Satellite

    Josh] has a series called Ham Radio Crash Course and a recent installment covers how you can grab satellite images directly from weather satellites. This used to be more of a production than it is now thanks to software defined radio (SDR). Josh also has another project using a 3D printer to make an antenna suitable for the job.

    The software is the venerable WXtoImg program. This is abandonware, but the community has kept the software available. The program works on Linux, Windows, and Mac. The satellites in question operate around 137 MHz, but that’s easily in the range of even the cheap SDR dongles. [Josh] shows how to use a virtual audio cable on Windows to connect the output of the radio to the input of the WXtoImg program. Under Linux, you can do this with Pulse or Jack very easily without any extra hardware.

    Software Defined Everything With Mike Ossmann And Kate Temkin

    Software defined radio has become a staple of the RF tinkerer, but it’s likely that very few of us have ever taken their software defined toolchain outside the bounds of radio. It’s an area explored by Mike Ossmann and Kate Temkin in their newly published Supercon talk as they use GNU Radio to do some things that you might find unexpected.

    3.2 GHz Vector Signal Generator Tear Down

    [The Signal Path] snagged a fancy Rohde & Schwarz vector signal generator that can go up to 3.2 GHz, but sadly it wasn’t in working order. It powered up and even put out a 1 GHz signal, but the amplitude output was very wrong. Interestingly relative changes to the output were correct, it was just that the absolute output amplitude was off by quite a bit and changed with frequency. That started a detective job which you can follow along in the video below.

    Flipper Zero is a portable multi-tool for pentesters and geeks in Tamagotchi body. It loves to hack digital stuff around such as radio protocols, access control systems, hardware and more. It’s fully opensource and customizable so you can extend it in whatever way you like.

    BAE Systems delivers first radiation-hardened RAD5545 radios

    RAD5545 software defined radios are on their way to Lockheed Martin to support future space missions.

    BAE Systems’ software defined radio is anchored by the RAD5545 single board computer (SBC), providing the most advanced radiation-hardened quad core general purpose processing solution available today to address future threats on a variety of missions. The system leverages modular and standard building blocks including a SpaceVPX chassis and backplane electrical connectors, Serial RapidIO and Spacewire interfaces, and a fully supported expansion port for a custom interface card.

    Hurricane Watch Net for ISAIAS on NA5B WebSDR

    Hello all. For those who do not have their HF up and running, there is an alternative way to listen to the Hurricane Watch Net for hurricane ISAIAS which is going to hit Florida and the East coast states in the coming days.

    Here is a link for the WebSDR server that I have been running for some years, a 24/7 basis in Washington DC Area.

    Best regards

    A fully-contained software-defined radio solution in tablet form opens new doors for field testing.

    RadioSlate: A Software-Defined Radio Tablet

    A fully-contained software-defined radio solution in tablet form opens new doors for field testing.

    Tools like signal and spectrum analyzers are extremely important in the RF world, however they can be extremely expensive pieces of equipment to purchase and not the most portable or space friendly. To fill the gap, software-defined radio (SDR) hardware and software has become extremely popular as much of a radio structure can be digitized to make use of less expensive RF circuitry and fit into a compact package.

    The market for SDRs has grown over the past few years as makers and hobbyists have sought out better understanding of the wireless capabilities of their hardware. Engineers in industry have also started taking advantage of SDRs for mobile testing setups in the field or just to take advantage of a tight lab bench.

    The RadioSlate serves as a sturdy aluminum tablet powered by an Intel M3 8100Y dual-core SoC for a CPU, an Arduino Leonardo for an MCU, Intel UHD Graphics 615 GPU, 8 GB LPDDR3 RAM, and 1024 x 600 pixel touchscreen. RadioSlate is a fully-contained computer loaded with Ubuntu LTE (but also supports Windows 10 if a user desired to re-image it).

    Alongside the standard dual-band 802.11ac Wi-Fi and Bluetooth 4.2, RadioSlate contains a slot for either a LimeSDR Mini or HackRF One to connect to the CPU.

    We learned from the web that the Electronic Barking Dog Alarm has an electronic radar-wave sense management.

    the Electronic Barking Dog Alarm because solely motions from the rear and from the sides are detected.

    GNU Radio Decodes Voyager Data

    With the 44th anniversary of the launch of Voyager I, [Daniel] decided to use GNU Radio to decode Voyager data. The data isn’t live, but a recording from the Green Bank Telescope. The 16 GB file is in GUPPI format which stores raw IQ samples.

    The file contains 64 frequency channels of just under 3MHz each. The signal of interest is in one channel, so it is easy to just throw away the rest of the data.

    A Python block manipulates the file and provides a data source. Once you have that, the rest is pretty standard processing although, as you might expect, the signal is weak even with a 100 meter antenna. Large Fourier transforms do the trick.

  14. Tomi Engdahl says:

    We got a tip this week on a video about how 1/4-wave tuning stubs work. It’s a simple demonstration using a length of coax, a signal generator, and an oscilloscope to show how an unterminated feedline can reflect RF back to the transmitter, and how that can be used to build super-simple notch filters and impedance transformers.

    .We love demos that make the mysteries of RF a little simpler — W2AEW’s videos come to mind, like this one on standing waves.

    The Coolest Radio You’ve Probably Never Heard Of

    Software Defined Radio (or SDR) is one of those things that I never knew existed as I was getting into the radio hobby. After learning about it, it’s one of the coolest radios in my humble communications arsenal.

    In this video I want to introduce you to SDR, and share just the slightest glimpse of what it has to offer in the hope that it inspires others to get into it and learn more.

    Raspberry Pi Tablet Gets Radio Surgical Enhancement

    We always get excited when we buy a new tablet. But after a few months, it usually winds up at the bottom of a pile of papers on the credenza, a victim of not being as powerful as our desktop computers and not being as convenient as our phones. However, if you don’t mind a thick tablet, you can get the RasPad enclosure to fit around your own Raspberry Pi so it can be used as a tablet. Honestly, we weren’t that impressed until we saw [RTL-SDR] add an SDR dongle inside the case, making it a very portable Raspberry Pi SDR platform.
