Holla master PICxperts: This is my first time in this PICLIST. I'm making a mini pager system. This system have one TX and 10 RX, in max d istance of 70 m. I'm using a serial RS 232 protocol (from Parallax) to make the comunication. My problem is the RF link. If you have a circuit or a hibrid module, send m e informations. The frequency is not important, but if possible, 433 MHz. Tankx for all.
