[Helge Fyske (LA6NCA)] may not be an actual spy — then again, he may be; if he’s good at it, we wouldn’t know — but he has built a couple …read more Continue reading Spy Radio Setup Gets a Tiny Power Supply for Field Operations
Here at Hackaday, we love following along with projects as they progress. That’s especially true when a project makes a considerable leap in terms of functionality from one version to …read more Continue reading Spy Transceiver Makes Two Tubes Do the Work of Five
In our surface-mount age, it’s easy to be jaded about miniaturization. We pretty much expect every circuit to be dimensionally optimized, something that’s easy to do when SMDs that rival …read more Continue reading Tiny Three-Tube Receiver Completes Spy Radio Suite
It’s been a long time since vacuum tubes were cutting-edge technology, but that doesn’t mean they don’t show up around here once in a while. And when they do, we …read more Continue reading Two-Tube Spy Transmitter Fits in the Palm of Your Hand
Global supply chain issues are beginning to hit closer to home for the hacker community, as Raspberry Pi has announced their first-ever price increase on their flagship Pi 4. The …read more Continue reading Hackaday Links: October 31, 2021
Talk about buried treasure: archeologists in Germany have – literally – unearthed a pristine Soviet spy radio, buried for decades outside of Cologne. While searching for artifacts from a Roman empire settlement, the archeologists found a pit containing the Soviet R-394KM transceiver, built in 1987 and apparently buried shortly thereafter …read more
World War II can be thought of as the first electronic war. Radio technology was firmly established commercially by the late 1930s and poised to make huge contributions to the prosecution of the war on all sides. Radio was rapidly adopted into the battlefield, which led to advancements in miniaturization and ruggedization of previously bulky and fragile vacuum tube gear. Radios were soon being used for everything from coordinating battlefield units to detonating anti-aircraft artillery shells.
But it was not just the battlefields of WWII that benefitted from radio technology. From apartments in Berlin to farmhouses in France, covert agents …read more
