Yes there are many, it all depends on what software you want to use for both SDR and the decoding but there are many on youtube
Also if you just want to have a quick go at it you could technically just download an RTTY app on phone and hold it to the computer speaker. I do this all the time with DroidRTTY when I'm playing with the GlobalTuners remotes. Though if you're going to be receiving data modes regularly I would recommend the MultiPSK setup.
