  Great price.

  Nothing in the data sheet about distance.
  Good luck with the data sheet by the way.

  Well it's .25 to 2 mw output so I guess it would depend on your antenna.

  From the description on the SparkFun site, it sounds like this chip is designed for transmitting stereo audio, not data.

  Can a received audio signal be used to carry data ? like a fax machine, or could two digital data streams be sent/received ?

  If you look in their wireless section under general, you will see they have some economical transmitter/receiver pairs that are made for data transmission. I have no idea how well they work, but its probably better (and easier) than adapting a FM stereo transmitter to do the job.

  Your comment made me remember a wireless test in the Sparkfun tutorials.
  Speaks to your question.
