hi friends,
i have connected the output of the micro-controller (atmega32l)to the data line of the TX 433 mhz , and i have provided 1 and 0 alternating bits pattern to each pin with a delay of 500 ms .
the problem is only 1 pin is responding correctly to the data transmitted by the TX . all other data pins of the RX are high , except 11 pin . So where i am going wrong . I have made the ground same of the TX and the micro-controller unit .

Here are some references to help you along:

If these don't help, provide a schematic and code for your controllers...
