FPV drones are a signature weapon of the Ukraine conflict, and jammers to stop them are a matter of life and death. Both sides have fielded jammers and drone guns firing a beam of radio waves to knock out drone communications, said to take out thousands of drones a month. Now a Russian group claims to have developed a ‘magic radio’ for FPVs which is highly resistant to jamming. A physicist with the handle DanielR evaluated the device minutely in a detailed Twitter thread.
“From a technological perspective there is nothing surprising here,” DanielR told me. But the device does make efficient use of cheap, off-the-shelf components.
Racing quadcopters converted into cheap kamikaze drones are used by both sides. They are capable of diving into foxholes and bunkers, chasing down trucks, and even destroying main battle tanks from five or more miles away. Often jamming is the only protection, but this device claims to nullify it.
