    I am relatively new to electronics, so ...
    I want to transmit a signal 20 to 30 yards, can someone spare the time to help me with this?
    I have a supply voltage on the transmitter of a 3volt battery (I could double that) and 1.5volt for the receiver.
    I was visiting Digikey and I need to match up the smallest transmitter and receiver combination to go that distance.
    What frequency range??? 300MHz to 400MHz??? I'm not sure what to use, so I can transmit just for circut on/off, not data or anything.
    Thanks, (email if you want) <snip>

    What is the nature of the signal? Voice, data, something else?
