Demonstration of the Blue Raider that jamms a K band speed sign.
Allthough this test worked, the jammer doesn’t work in real life situations! Simple radars like this K band Speed sign and Bushnell K band radargun are jammable, but only if you are close enough to the (simple) radar. When driving by a Police radar there will be at least 1 real speed reading. Do not buy the Blue raider jammer, it’s a SCAM!
