So I was watching a program last night about Jupiter and appearantly one can pick up radio signals on the AM band created in the planet's magnetosphere! I did some further research on site that says the signals come in best on shortwave radio between 15 and 40 MHz, "broadcasting" at two trillion watts. Has anyone ever tried this?

Radio emissions from other planets?

Hi Dustin. I've heard their broadcasts in the past. I have had a bit more trouble picking them up though lately since they recently moved their transmitter somewhere beyond Uranus.

What you are talking about is scientifically conceivable but I have forgotten the details of how it works. Between 15mHz and 40mHz is a broad range on the dial so you would need to get more info. I don't know what it would sound like because there are no voices or people.
Call Dr. Bill Wattenburg about this on KGO news/talk 810 San Francisco, Saturday and Sunday nights, or Bryan Styble on KIRO news/talk 710 Seattle, Sunday night.
If the sounds are voices, what should we do?
NASA has audio samples of the different sounds coming from Jupiter here:

NASA recently also has collected audio from radio emissions from Saturn picked up by the satellite Cassini currently orbiting the planet. That audio is here:

LOL!

Good buddy of mine, he in all earnestness, wound up privy to a telescope and a spectrum analyzer and the devil-knows what else equipment at a far East End Long Island Observatory in the mid-Eighties. No one knows what drove him to meet this agenda. Yet he persisted in linking astronomy and DX.
He and his wife would be at the controls and knobs and dials and coffee cups while I was in another room and trying to learn the courtesy piano which the Southold observatory kept as some sort of traditional courtesy.
And one night, my buddy nailed his quest. Jupiter. It showed up starkly as a decided bunch-up of blips on the oscilloscope. The visual inkblots said something was apparent.
Of course, they didn't ID, or have jingles, or have processing, or a QSL. But there, in some physical form on the meter, was Jupiter. On the screen. My buddy wouldn't lie. Why else would he drag his wife and anyone else who wanted to come along to an observatory at midnight?

All joking aside (and it's been pretty amusing ), there is something to this.
Apparently, Jupiter's magnetic field is so massive that it has been known to interfere with radio communications with a specific type of static blast that can be heard on LW/AM/SW frequencies. We actually pass through the "tail" of Jupiters magnetic field at times...it's that big. However, this sort of thing only happens at very sporadic times and at varying levels of strength. In other words, it's very hard to catch.
Also, hearing the trademark static of Jovian magnetism while listening to AM at night used to be easier before the days of things like computers, wireless routers, big TV screens everywhere, compact fluorescent bulbs, and any of 10,000 other interference emitting devices. So, even when it happens, it's pretty much drowned out by all of the other stuff.

I listened and it sounds just like dead time on the network
coming down an old 3.5 kHz un-EQed Telco line that was
typically found in small-market radio (before satellites).
I think NASA cut off the sound sample just before:
Bong!...(sounder)...CBS News, Allen Jackson reporting
on the CBS Radio Network...
