LoRa (Long Range) radio uses little power and can communicate at up to three miles in urban areas and five miles or more in the open. Many drone operators now use a repeater, carried on another drone, to extend the reach

First-person view (FPV) drones are quickly becoming a key weapon in the Ukraine conflict. There is rapidly developing drone warfare involving thousands of drones every month. Both Russia and Ukraine have fielded jammers and drone guns firing radio waves to knock out drone communications.

Most recently 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. While the technology is not astounding, what is interesting is that the device uses cheap, off-the-shelf components.
