Thanks, David. I'll have to try HF in one of my Leafs. It's on the list. 73, Art -- Arthur I.

The author obviously is a little mixed up about at least one aspect: disregarding simulcasts, AM stations that broadcast in HD are still on their AM frequency (not some FM frequency). A pretty good summary of digital AM & FM radio in the U.S. is at this link: https://en.wikipedia.org/wiki/HD_Radio.
Another reason some auto radios no longer have the AM band is because AM band broadcasting has ceased in some countries (much to the happiness of some 160 meter ham operators). Denmark, for example, ended AM broadcasting at least a decade ago; and FM broadcasting is due to be shuttered within a few years as it is increasingly being abandoned for digital broadcasts (which have their own separate band unlike here in the U.S.). I believe that Norway shuttered analog FM years ago.
BTW, in addition to being superior in sound to AM & FM broadcasting, digital broadcasting uses much less electricity and therefore can be provided more economically --- especially by smaller broadcasters.

My Nissan Leaf has AM radio. I found this an interesting article. Does it relate to having an HF radio in an EV?
