Does it work with arduino ? What about receiver ?

    seems fantastic module, specially for price / range ! Does it work with arduino / is there any demo of similar device ?

    Also , does anyone have to suggest any receiver for that ? Is there any way to have many transmitters and one receiver ?

    Yes it should work with Arduino.

    Yes, it works with arduino (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1265577307), but DX should also provide the receiver (TDL 9921), otherwise it's not very useful...

    Well, the receiver is there now: TDL-9921

    However I don't know how to connect it.
    Also there are a few other receiver modules too: TDL-9915, TDL-9915RXF, TDL-9927, TDL9927A - no info on those either.

    Range is highly dependent on supply voltage. The higher voltage you supply the more transmit power you get.
    I have a very similar transmitter (f = 434 MHz) from another site and receiver (clone of SKU128977) as well.

    One could maybe like to see transmitter schematic. Transistors, that are actually soldered on the board then set the limit for maximum supply voltage.

    There is a great library for Arduino VirtualWire. For personal usage I have library, that uses Manchester encoding, which is not such efficient as 6 to 4 encoding in VirtualWire, but still performs well.
