433Mhz RF with Manchester lib won't work

Hello,
I’m trying to send data from an ATtiny84 [1mhz] to Arduino Uno using a 433Mhz rf module and Manchester lib.
Now I came across a weird problem, no matter what value I transmit, When I receive it on the arduino and to the Serial monitor, it always shows value of 806,No matter what I have really transmitted.

ATtiny side

void setup()
{
  man.workAround1MhzTinyCore(); //add this in order for transmitter to work with 1Mhz Attiny85/84
  man.setupTransmit(transmit_pin, MAN_1200);
}

// And how I transmit
// RGBread is int, I also tried man.transmit((uint16_t)RGBread[i]); same result.
  for(int i=0; i<3; i++)
  {
    man.transmit(RGBread[i]);
  }

Arduino Uno

void setup()
{
  man.setupReceive(reciever_pin, MAN_1200);
  man.beginReceive();
}

  if (man.receiveComplete()) {
    Serial.println(man.getMessage());
    man.beginReceive(); //start listening for next message right after you retrieve the message
  }

Any help would be very appreciated!
