![]() We’d venture a guess that a directional antenna would make the search much easier than the whip shown. We can’t say we’d recommend confronting anyone based on this information, but at least you’d know your car is at risk. In theory you could walk through a parking lot until you get the strongest signal and locate the bad guys. The SDR is set to listen to the band used by key fobs for the continuous, strong emissions you’d expect from a jammer, and the Pi generates a tone that varies relative to signal strength. His jammer locator consists of an SDR dongle and a Raspberry Pi. Inspired by a recent post featuring a simple jammer detector, decide to build something that would provide more directional information. If you want to be sure your car is safe, you might want to scan the lot with a Raspberry Pi and SDR jammer range finder. But there could be evildoers lurking in that parking lot, preventing you from locking up by using a powerful RF jammer. We all do it - park our cars, thumb the lock button on the key fob, and trust that our ride will be there when we get back.
