does anyone know or have a schematic of a circuit to turn IR pulses into RF signals and then back again. So you can hook up a tv remote to a trasmitter and then at the receiver change it back. This doesn't seem that hard but i would like something with good range (i would like 1 mile+ but i won't get my hopes up) or something i could hook an amp. and please don't send links to tv remote exdenders, i don't want to get those. thanks and help.
