Unfortunately, the signal is two noises causing the value to fluctuate wildly. The instability also means that the LEDs are on for a very short period so its difficult to see the lights change their state.

Disco Bike - Radio test
This is a test of a cheap 433Mhz transmitter and reciever from SparkFun electronics. Together they cost only $7 for the pair. I did a test with two arduinos one transmitting data and the other recieving, both outputing over serial to debug. The fidelity seemed pretty good (Although it was only short range ~1m) without an antenna. This video shows a test using the musical output of the computer which is sent to an anolog pin on the arduino. The Arduino reads the voltage and sends a byte to the transmitter. The receiver on the other end then pulls that value in and is SUPPOSED to adjust the brightness of the LEDs accordingly.
