They are just normal Rx/Tx with stated range upto 150 Meters. They actually work very well upto 100 Meters when I use it for toggling pins high or low (my other kind of switch- Tx button pressed once, receiver switches on somthing, Tx switch pressed again - receiver switches it off) at the receiver. But dont know why the receiver PIC latches up in this kind I am making where it should only stay on untill TX is pressed.
