At this point in time you are much better off buying one of the ones made by wise lite, tearing it down, removing all the rough edges, refinishing it and fine tuning it to make it work reliably. trying to cobble together a receiver from all the stuff that is available is a waste of time & money. trust me I have built a few of these and they are not easy to get working reliably and to keep working.
I am not trying to dampen anyone's enthusiasm , just trying to save you a lot of frustration!!
