rx-tx modules


I just bought a pack of two modules, one receiver and one transmitter.
Did someone already used some of these?

If yes, can you tell me if you can use them for voice transmitting and receiving? Or they can be used just for other type of data?

Thank you

More info needed on the modules to be able to answer this.


Here is a kink for the web site from wherr i ordered them.

If you need more info, i can do some research on it


Those generally have a limited data rate. Virtualwire library limits the data rate to 2000 bits/second, and 27 (37?) bytes of user data with Manchester encoding & other support around the data: http://www.airspayce.com/mikem/arduino/VirtualWire/

I don't see any links to data sheets for the modules, no part numbers to look one up.
