    Is there anything in particular that I am doing wrong in order to get the rf link to work?

    OSCCON =$60 'sets internal osc to 4MHz
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    I might not know what's wrong...but I know what's probably not helping matters any...

    yes, sorry my mistake.

    I have taken that bit of code out but it still doesnt work.

    Well, it does work occasionally when disconnecting and then connecting the power to the transmitting circuit, but it seems very unreliable that it may as well not work, but at least i no it is receiving data sent across the rf link. Is there something to make it more reliable. I have tried several different baud rates and pre ambles but nothing seems to make it more reliable.

    thanks

    I agree with Mr.mask. Lucky the internal osc works with wires, RF is even more touchy.

    If changing the osc does not help, test the RF.

    The 010101... is for setting up the receiver for serial input. Test the RF by sending a HIGH and then a LOW. Have maybe a half second pause between the signals.
