Radio Transceiver Effects on Car Electronics

This article discusses the potential effects of radio frequency (RF) energy from transceivers on vehicle electronics. It begins by describing personal experiences with VHF/UHF radio signals activating motion lights, home alarms, and smoke alarms. The author then considers the interaction of transceivers with car electronics, referencing military Radio Frequency Vehicle Stopper (RFVS) devices designed to paralyze vehicles with RF blasts. The article notes the challenge for RFVS manufacturers due to vehicle variations, leading to the development of multi-frequency RFVS (MFRFVS) to increase effectiveness. It then addresses whether amateur radio installations can impact a vehicle's electronics, concluding that it can, but the extent varies. The article suggests that car manufacturers test products against external RF energy, with luxury car makers likely conducting more extensive research than others who may only meet minimal certification requirements. The author raises the question of how amateur radio operators can assess the impact of their installations.
