- Tesla are removing AM radio…maybe because of the antenna? AM/FM chipsets are available in single silicon packages
E W says
Dave was wrong that AM reception requires a ferrite rod. They are highly directional and would be shielded inside a metal body car. AM car radios use a short whip antenna, usually the same as serves the VHF FM front end. Apart from declining usage of AM I wonder if another reason for Tesla to drop AM is because of the high level of interference from their drive train switching and resulting harmonics – remember AM broadcasts are 520-1700 kHz – right where folk now run switchers!
