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.
