This is a bit frightening..

We found 4 different ways (including the Kuhn attack) to fully or partially recover keystrokes from wired keyboards at a distance up to 20 meters, even through walls. We tested 12 different wired and wireless keyboard models bought between 2001 and 2008 (PS/2, USB and laptop). They are all vulnerable to at least one of our 4 attacks.

We conclude that wired and wireless computer keyboards sold in the stores generate compromising emanations (mainly because of the cost pressures in the design). Hence they are not safe to transmit sensitive information. No doubt that our attacks can be significantly improved, since we used relatively inexpensive equipments.

There are videos on the site showing how this is done. Read the FAQ otherwise you may wonder if it is fake.

I am sure many here know all too well how computer interference can be received so easily over radio. In fact it is very annoying when trying to listen to a station and the damn keyboard or mouse goes right over the audio making the computer sound like the ones in movies with beeps and techy sounds.
On that note I should mention how stupidly annoying it is when they do that in movies and TV shows when no ones computer does that in real life. Of course it is equally stupid how their computer graphics look on TV shows like CSI but I digress..

I always figured it would eventually be possible to decode keyboards via that method but never seen it actually done until now.
I like how in the second video they use a wideband biconical antenna which makes perfect sense since keyboards generate wideband RFI.
Either way it is creepy and if this is just the beginning of their progress I can only imagine the eavesdropping that will take place in the future.
So how long until they can monitor the RF noise hard drives make and decode files being saved to them in real-time?
