S Savashi New Member Feb 12, 2009 #1 I'm interested in building an RF transmitter / receiver pair. The application is to send a signal to light up an LED when a switch is closed. I'd like to build this out of simple discrete components rather than using a an IC. The range needs to be around 100 yards. Any idea where I can find sample circuits? Thanks
