Hi guys, im using a Trasnmiter and reciver, FM i gues, but i dont know bought some where on internet. It has a procesor of PT2264 and other is with an ending of sc2272.This one http://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_92&products_id=344

So im having quite a problem in my head, and not only in it :)

I have a question how can i use it to communicate? Does it use voltage or digital signals?

Yes. Digital signal ARE voltage.

I don't believe I've ever seen a radio that said this before:

Warning: this kit is not suitable for data transfer but remote control. Safe for 2 commands/second.

That's pretty slow. I doubt that you are really going to be able to use these radios for anything useful.

What did you want to use them for?

I want to use it for, lets say number transfere, or 0 or 1.

Acctualy any information just want to see how it communicates
