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:

https://hackaday.com/2024/03/27/automatic-position-reporting-over-hf-radio/
A tool called the Automatic Packet Reporting System (APRS) is fairly robust in the very high frequency (VHF) part of the amateur radio spectrum, but this solution still relies on a not-insignificant amount of infrastructure for the limited distances involved with VHF. [Lonney] adapted a few other tools to get APRS up and running in the HF range, letting his friends keep tabs on him even from the most remote locations.

Längstwellen-Empfang mit der Soundkarte bei geringem Aufwand
Mit einem minimalistischen Aufwand und der Hilfe der Soundkarte des PC lässt sich ein Empfänger für Längstwellen von etwa 9 bis 23 kHz aufbauen. Als Antenne reicht schon ein Draht, der möglichst lang sein sollte. Bereits 10 m Draht haben bei meinen Experimenten zu guten Ergebnissen geführt. Die Dekodierung übernehmen kostenlosse Programme, welche es im Internet gibt.

FOBOSSDR: A NEW SDR RECEIVER WITH 100 KHZ TO 6 GHZ TUNING RANGE AND 50 MHZ BANDWIDTH FOR $395
Recently we’ve seen that a new SDR from the Ukrainian company RigExpert has been released. The RX-only USB3.0 SDR is called ‘FobosSDR’ and it has a 100 kHz to 6 GHz tuning range, 50 MHz of bandwidth, and 14-bit resolution. Apart from a standard RF input, it also has two auxiliary input channels for coherent direct sampling and clock in and out ports.

Suomalaisen Bittiumin ohjelmistoradiotekniikkaa hyödynnetään tulevissa Naton Oulun testikeskuksissa. VTT:n ja Oulun yliopiston yhteyteen tulevissa Diana-keskuksissa Nato-maiden eri puolustusvoimien käytössä on alan uusin tietoliikennetekniikoiden tutkimusinfrastruktuuri.
Naton uusien Diana-testikeskusten tehtävänä on auttaa Nato-maiden yrityksiä vahvistamaan omaa teknologista osaamistaan ja kilpailukykyään. Ne tarjoavat työkaluja teknologiakehitykseen ja niiden teknologiateemat liittyvät seuraavan sukupolven kommunikaatiojärjestelmiin, 6G-teknologiaan, kyberturvallisuuteen sekä kvantti- ja avaruusteknologioihin.
Bittium kertoi tiedotteessaan toimittaneen jo tuleviin testikeskuksiin Tactical Wireless IP Network (TAC WIN) -ohjelmistoradiojärjestelmän ja Tough SDR -sotilas- ja ajoneuvoradioita.

Alex R2AUK] has been busy creating version two of a homebrew all-band ham radio transceiver. The unit has a number of features you don’t always see in homebrew radios. It covers the 80, 40, 30, 20, 17, 15, 12, and 10 meter bands. The receiver is a single-IF design with AGC. The transmitter provides up to 10W for CW and 5W for single sideband operations. There’s a built-in keyer, too. A lot of the documentation is in Russian (including the video below, which is part of a playlist). But translation tools are everywhere, so if you don’t speak Russian, you can still probably figure it out.

[Scott Manley] Explains GPS Jamming
https://hackaday.com/2024/05/19/scott-manley-explains-gps-jamming/
We always think of [Scott Manley] as someone who knows a lot about rockets. So, if you think about it, it isn’t surprising he’s talking about GPS — after all, the system uses satellites. GPS is used in everything these days, and other forms of navigation are starting to fall by the wayside. However, the problem is that the system is vulnerable to jamming and spoofing. This is especially important if you fear GPS allowing missiles or drones to strike precise targets. But there are also plenty of opportunities for malicious acts. For example, drone light shows may be subject to GPS attacks from rival companies, and you can easily imagine worse. [Scott] talks about the issues around GPS spoofing in the video,
Since GPS satellites are distant, blocking the signal is almost too easy, sometimes happening inadvertently. GPS has technology to operate in the face of noise and interference, but there’s no way to prevent it entirely. Spoofing — where you produce false GPS coordinates — is much more difficult.

The Pi Pico, An SDR Receiver Front End
https://hackaday.com/2024/06/05/the-pi-pico-an-sdr-receiver-front-end/
Making a software defined radio (SDR) receiver is a relatively straightforward process, given the right radio front end electronics and analogue-to-digital converters. Two separate data streams are generated using clocks at a 90 degree phase shift, and these are passed to the software signal processing for demodulation. But what happens if you lack a pair of radio front ends and a suitable clock generator? Along comes [Mordae] with an SDR using only the hardware on a Raspberry Pi Pico. The result is a fascinating piece of lateral thinking, extracting something from the hardware that it was never designed to do.
The onboard RP2040 ADC is of course far too slow for the task, so instead an input is used, with a negative feedback arrangement from another GPIO to form a crude 1-bit ADC. A PIO peripheral is then used to perform the quadrature mixing, resulting in the requisite pair of data streams. At this point these are sent over USB to GNU Radio for demodulating, mainly for convenience rather than necessarily because the microcontroller lacks the power.
