Members, my self included, are reluctant to download code. It is a PITA. Read the forum guidelines to see how to properly post code and some hints on how to get the most from this forum.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.
Post both the transmitter and receiver code.
Please include a schematic showing all components, their values and/or part numbers and all power supplies.
