Re: AM Radio in EV's
Actually, now that I think about it, the only time we had a real Emergency Broadcast Alert here in the Bay Area was during the big quake of 1989.  All radio stations went off the air except the two authorized to broadcast during an EBA.  We have had a few alerts for storms, fires, etc, but those were warnings, not emergencies.   I wonder if the rules have changed for EBA?

Some things only on AM
In some markets (areas), some radio programming might be available only on AM.

Boston, MA is SOMEWHAT an example.  WBZ (AM) is known for its comprehensive traffic reports updated every 10 minutes.  I think WBZ might simulcast on an "HD" channel on FM, but I have not driven a car that can receive that.  So *my* only option in a car is to hear them on an AM radio.  Would FM stations pick up the void if AM radios disappeared?  Doubtful.

Re: AM Radio in EV's
I'm pretty sure Emergency Alert Notifications go out on all broadcast stations, not just AM.  I don't think any are exempt.

The cell phone situation is changing.  But some cell phones do not receive alerts.  No attempt has been made to reach all cellphones.

What's radio, anyway?
I've reached a point where I can't listen to any form of commercial radio. The ads are too annoying. As for noncommerical or public radio, why bother? I stream using my phone.

AM Radio in EV's
Hi Bill,

Good article - I have to say I am surprised that the auto manufacturers didn't bother squish their emissions enough to put AM in their cars.   Where are the analog guys when you need them?

One issue I see is the Emergency Broadcast Alert, which is sent out on AM radio, not FM, and not on cell phones either.

I see some legislation in our future here....

How can you accurately measure this impedance to give reliable lead-off detection in ECGs?
Fast switching transitions can yield some disadvantages. Interference in the frequency range of the switching transitions between approximately 20 MHz and 200 MHz increases dramatically.
The U-channel format consists of an open frame PSU mounted into a U-shaped aluminum chassis.
The primary difference between the speakers I designed and the micro- and mini-speakers that Eminence makes is that the diaphragm is connected directly to the voice coil as opposed to an Aluminum or cardboard 'former' to which the voice coil was connected
