433 Mhz Data Receiver

[Pesticida]

Hi,
yes I have a receiver and a transmitter.
The receiver is connected trough a RJ11 cable to a PIC controller,now when I push the transmitter button the first time the PIC save the data from the transmitter to the pic memory,and now I can use the button with this receiver and PIC.
Do you understand what I mean.
I looked on the receiver,I receive all the time data from all buttons what I have but the PIC can just switch the output when I push the button what I have saved .
The PIC Schematic look like this,I draw just what I need.
My question is how can I do the same cicuit on my PIC 16F870 and what command I need to do this.I connect the receiver to my PIC but I receive all the time strange data and when I push the button I receive data to, but is all Mixed.

Thanks Pesti.
