Reviving TEMPEST Attacks With An Injected Signal

TEMPEST attacks are often the most effective way to break air-gapped security: rather than directly accessing a computer, the attacker records the system’s unintended radio emissions and uses them …

I ordered a bunch of antenna books from #ARRL and was hoping for more information and advice above 1ghz. I'm looking at RF cables for making #meshtastic #antennas, but I also want to use them with my decade-old #SDR that goes up to 6Ghz. And I have interest in higher frequencies. To set expectations, I remember 900mhz radios were sold by radio shack when it existed. 2.4 ghz was commonplace 20 years ago. Cellphones and wrist watches now use 5ghz wifi, and cruise control for cars uses 77ghz. But the highest freq in the books are the UHF to Microwave chapter. It spends a lot of time on UHF and VHF, and the diagrams mostly go from 1-100Mhz. A few tables show losses at 1 ghz, and a single graph shows 10ghz. I'd love to see separate chapters (or books) dedicated to microwave and mmwave, maybe with some hints about thz. Especially if it has the practical wisdom the HF bands get. E.g. What's the best way to connect to a 5ghz yagi? I'm not the person to write them, unfortunately, but I'd love to read them.

Hackaday Europe 2026: High Performance SDR On The Cheap

Radios were once big complicated appliances, full of warm valves and paper-wrapped capacitors, all humming and glowing to capture signals from the aether and spit them out of a speaker. Every compo…

I suppose this is true, strictly speaking, but only in the same way that using a computer or a mobile phone could end up with you introduced to the same set of friends. "Most excitingly, you can download apps for [Software Defined Radios] that do everything, most especially the kind of thing that will introduce you with surprisingly rapidity to a wide range of new friends with no sense of humor and love letters that look suspiciously like arrest warrants."
