AVR-Chat

Hi everybody, i'm having trouble.....

I am trying to transmit data over Rf using 2 atmega8l(via USARt) and 433Mhz
transmitter and reciver module. One will work as transmiter and the other as
reciever. The transmiter will send a code composed of:
	-----------------------------
       | SYNC |Package|CHECKSUM|end|
       -----------------------------
all of this coded as manchester. Afer sending the package, the mega8 will
shut down the transmitter until next transmition.
The reciever would listen to the reciver module only when it is desired,
selecting this with a pushbutton.When i dont want to listen, i shut down the
433 reciver module
Here is the problem:
	i dont seem to sincronice the transmitter and the reciver usart, because
when the transmitter is off and the reciever is on i keep getting and
Framming error.
     i've tried listening to the RXd pin, with the RXEN=0, till i get a
long enought "1" and then set the RXEN=1, but this seem to have no
effect.........
Any ideas of how to sincronice them????????????

Thanks
Javier
