Could you post a link for a transmitter and receiver like that. I am interested in something similar and couldnt find them for under $10 when searching for 433 mhz. Where did a google search for Q kits but nothing came up.

thanks

For The Receiver it says its range is 200m in open air what if it gous throue walls and its about 75m. will is still work??

Depends on what the wall is made of. Wood or concrete should not reduce the range unless there is a lot of wire or reinforcing rod in it. A steel building or stucco on wire mesh will block the signal.

Does anyone have datasheets for those things?
The receiver has one "linear" pin while transmitter
has code input. If the linear output is analog, what
is the resolution? What is the code format used by
transmitter?

The transmitter does not have a code format, it accepts whatever modulation is input. I have not tested it, but believe that a sinewave input to the transmitter will be a sinewave out of the linear output of the receiver.
