FM???
Doesn't AM work better.......with skywave....especially at night??!
Well.....if we humans don't want to work with AM....maybe the ALIENS can do something with it:
"Covering the Galaxy......and parts of.......FRANCE......This is Conehead Radio....
Music that'll grab your snarklies.....!!!"

FM band frequencies do not bounce of the atmosphere. So it has the ability to travel in straight lines across space. Note that satellites and spacecraft do not use the AM band, either.
Hopefully they got music and not news/talk.

Jupiter gives off tons of RF naturally. The article said "FM", not because it's playing music, but because the strength of the magnetic fields "modulates" the frequency somewhat.
There used to be a "Project Jove" that was operated by NASA with schools around the country. Kids got instructions and even kits to build antennas and receivers, to receive the lower frequency bands, and track Jupiter as it rose above the horizon. You can Google it, and build your own.
Here's a link to a tutorial (the DIY stuff is elsewhere):

Here is a pretty well respected paper/opinion on the chances of either receiving radio signals from another civilization, or them hearing ours:
It's particularly interesting to contemplate the statement, "So, it is quite probable that, at some point in every civilization’s development, all its radio emissions will completely stop."
So radio communications, in the greater perspective, is as ephemeral as Citizens Band was to Baby Boomers.

I had to look up "conehead" in Wikipedia to understand that one.FYI, all.....
My comment about AM was an attempt at "tongue-in-cheek"..
Ergo the "Conehead" reference.......

Suppose there's an advanced civilization 10,000 light years away from us looking for radio signals from Earth? They might hear our broadcast signals of today, 10,000 years from now.
We are not talking just about broadcast radio... we are talking about any kind of radio frequency signal carrying data or information and that includes not just radio but everything that is on the part of the spectrum that can carry information.
Oh, and broadcast radio, which is used by nearly 90% of all people each week, has not stopped... it still has the broadest reach of any audio information and entertainment medium.
I should have clarified my statement, the FCC has killed radio

Oh! The FCC Media Bureau Chief told me more people would listen to radio if broadcasters would put something good on.
If you mean by licensing too many stations for a market to support, too many bad daytime or highly directional AMs and too many translators, I agree.
And that shows why we don't depend on the government for things best "regulated" by market demands.
Except for the last 10 months, radio stations and groups spend considerable monies on research to find what people want to hear, both at the format level and the content-within-the-format level. Radio programming is based on what large enough groups of listeners want to hear and which groups, at the same time, are of interest to advertisers.
In Marketing 101, we learned that the best way to get a bad product off the market was to advertise it. Consumers showed, by their rejection, that the product was disliked. Were the government to be in charge, we'd all be driving Yugos.

Of course, the market may demand it, and it may even become legal, but the government can still mess with things.
You can buy CBD almost anywhere now, but if, ten days later, you still have even a trace in your system, it's a DUI.

I've allocated many FM channels and started many radio stations. None ever went broke or dark.
However since I've been playing on here I see my Facebook stock has gone way down and Signal stock is way up. Looks like I missed the boat.
