Hi,

Please post your HW schematic with component numbers and values. It will be much easier for all of us if we can see what and how you connect to the PIC. Do you have the pic on 5V and the reciver also on 5V.. or are you running a 5V receiver on 3V ?

Step one must be to rule out HW and also make it possible for others to duplicate your setup for testing purposes.
