 		 #137291 - rf transmitter /receiver
hai all

i am trying to interface rf transmitter and receiver module to 89c2051.the frequency is 433Mhz and is ASK
the problem i am facing is that the receiver receives some junl data .how can i solve this problem?
can anyone provide some sample code for the transmitter and receiver?
i connected the transmitter module to the Tx of the transmitter 89c2051 and receiver module to the Rx of the receiver 89c2051.
is there some thing wrong with this?


thanking you all
