ARLA/CLUSTER: O porque dos vieculos eléctrico já não receberem emissões em AM na Onda Média

[João Costa > CT1FBF]

Electric cars shun AM radio

As an unintended consequence, two popular energy efficient cars from
BMW and Tesla are dumping AM radio, due to the vehicles interfering
with passenger reception on that band.

It seems that the rechargeable battery vehicles have an electric motor
with a frequency converter that disrupts AM broadcasts, which can be
prone to that kind of interference.

However all is not lost, with AM stations that are streamed on the
Internet able to be heard via the net in cars.

Meantime a team of engineers, on the side of loyal listeners, is trying to
find a technical solution that may include cable shielding and insulating
the motor.
