    Question Results for the hex files...

    Hi, Bruce. The PICs with these hex files are not working. So I put my setup on a breadboard and by using a piece of wire between GP.5 of both. I do see a voltage pulse on GP.5(Tx) of the Transmitter but no response from the receiver. I used 2400 Baud. I await your feedback.

    Can you post photos of what you have assembled & indicate which RF modules, power supply, etc you're using?

    Here is the photo of my bread-board setup. The LED to right of the 1uF Cap is for power indication.
    I don't have any technical details about these modules apart from that they are ASK based and are for short range RF applications. I have tested other simpler codes with them and PT enc/dec as well, everything works perfectly. They don't have any sort of marking on them as well so I can search the internet.

    My power supply if from 7805. Power supply is ok as I keep testing small projects every other day.

    Made a slight adjustment. These should work on pretty much any RF modules.
    Let me know if this version works for you.

    P.S. It's really hard to tell with that blurry yellow photo, but I would be a tad hesitant on lighting the LED on D3. It looks like the LED is wired direct to gnd on the cathode end?
