Hello,

i tried 2 transceivers Aurel XTR-434 MHz.

On one side, i used transceiver as a transmitter taking data from PIC16F876A.

On the other, i used the second transceiver as a receiver connected to PIC12F675 that displays numbers on LCD.

i used for both PICs crystals 4 MHz. but what happened?

data being sent from the first side is taking too much time to arrive to second part and be displayed on LCD.

Sometimes, it does not arrive at all whatever the distance is close..

I was told that it's because they do not have the same internal oscillator. i checked this on datashseets and found that they really have different internal clocks.

So is this the real reason for not receiving data? or might be something else?
