Hi,
I've got a friend who lives on a farm and is wanting me to make 3 wireless relay switches that can work up to 500 meters. Can anyone tell me how to go about it so that their frequencies don't get muddled up? I also need them able to change around the transmitter they receive from (or vice-vesa).
Also, can someone please tell me what is legal and what isn't with wireless devices?
Any circuit diagrams would be appreciated.
Thanks
