One last college try for RF modules

I am looking to add something similar to a project I am working on. Any luck since your last post? Have you done something more complex like this:

Also - (for MY reference) if you simple set the tranmist line to +5 does the the receive line go to +5? In my particular application all I am interested in is if the line is high or low. That's it - I am using it like a remote switch.... (I have not gotten my tx433/rx433 in yet).
