On and Off
Posted on July 29, 2010
I have a serious question for the engineering veterans who understand “remote controlled transmitters,” which refers to the method of turning a transmitter off and on from a distant location.

I have part 15 transmitters in several different locations within the same property, and would like to design a way of turning them off and on from a central location next to the computer. I prefer a home-brew system NOT integrated with computer control.
One objective is to avoid running 120VAC lines all over the place, like are used for switching lamps off/on. A low voltage system is sought, which will not draw current except when the button is pressed. If a plain relay is used, the relay coil draws current when it is in its “ON” mode.
Looking forward to your ideas.
