When I watch digital TV channels from terrestrial transmitters, I have to endure periodic disruptions during which the audio and images start stuttering. I recently realised that the disturbances occur every time motorbikes 鈥� and particularly scooters 鈥� pass my house. It doesn鈥檛 happen with cars. How do scooters disrupt my TV?
