Can't you use this to capture car-key signals and replicate them later? Sounds like the perfect tool for that.

I'm pretty sure car keys use a rolling code to avoid this type of attack.

Here is a spec sheet from '96:

Back then they used a 40 bit rolling code.

Are there any existing reliable alternatives?

BladeRF, USRP

BladeRF looks pretty awesome.

What cool projects could someone build with this besides scan radio waves?

Transmit and spoof things (i.e. pretend to be other devices)?

Your own GSM network for one. http://gnuradio.org/redmine/projects/gnuradio/wiki/Introduct...

Looks like it's essentially a Bus Pirate for RF... Which is awesome!

So, it's literally a piece of hardware allowing me to take any radio signal from 30MHz to 6GHz, transfer them into digital data and read them out with my Computer? (Or other device)

Man it'd be nice if this (or BladeRF) went down to DC like the USRP, so you could also use it as an oscilloscope. It's easier on the USRP because of its motherboard/daughterboard architecture, which adds some cost and complexity, but the cost adder should be pretty small relative to the several-hundred-dollars these things cost.

slow scan tv receiver for ARISS (Amateur Radio on the International Space Station). i implemented this as part of a class project using $20 tv tuners hacked into a crude sdr. http://inst.eecs.berkeley.edu/~ee123/fa12/project.html

If you want to try this stuff out cheap, then get a DVB-T dongle that works with RTL-SDR:

http://sdr.osmocom.org/trac/wiki/rtl-sdr http://www.nooelec.com/store/tv28tv2.html

bladeRf, USRP and now HackRF are def a step up but big difference in cost.

There is also http://www.RFSpace.com, http://www.Winradio.com and http://www.flex-radio.com for commercial offerings.
