"....many AM stations are still obtainable in new vehicles via DAB..." may be the correct assumption if driving around a metrpolitan area.
Such an assumption does not hold when driving in rural areas where DAB+ reception is non-existent where the only radio is AM or line-of-sight VHF FM.
The response by manufacturers to ditch AM because its reception is supposedly is interfered by an EV's motor is unadulterated bulls*@%t!
Ford is ditching AM on its fossil-fueled engines.
I have said many times that I have not experienced interference to AM reception when the electric motors in my hybrid are operating.
Demodulation of broadcast signals can be implemented by SDR which is more economical than using discrete components.
In summary, don't believe the reasons by the manufacturer for ditching AM.
Thank you,
Anthony, don't believe repeadted lies that becomes the truth because it ain't the truth, Belfield, in the land of the Wangal and Darug Peoples of the Eora Nation
Why such surveys are irrelevant outside of the USA.
The USA has no Government owned broadcasting for internal consumption. I understand that AM radio is mainly religious and shock jock broadcasters.
Their HDradio is not popular because a station's digital signal is transmitted in the channel of other broadcasters. This means that the power of the digital signal has a much smaller coverage area than the analog signal. They don't have any digital only HD radio broadcasts in the FM band. In AM band they have 3 low powered transmitters.
Whereas elsewhere DAB+ has a coverage area which is only slightly smaller than FM. We don't use Digital Radio Mondiale can cover the same area as FM but at one 1/10th of the transmitter power. It can also cover the whole of Australia from a single high powered transmitter.
The telcos particularly in the USA have been trying to convince broadcasters to use their mobile phone and land based internet services for their own profits. For example they stopped the enabling of the FM receiver which is within every mobile phone.
The BBC has found that the cheapest method of broadcasting programs to a large audience is using DAB radio. DAB+ is even cheaper per program. Now that DRM can also transmit 6 x 3 sound programs from a single transmitter it is also very cheap. Broadband and FM cost more and AM is the greatest. Lastly the last Telstra CEO is on record saying that Telstra is one of Australia's largest electricity consumer, thus produces lots of greenhouse gases. We also have two other telcos!
