  1. Hi,
    I'm a relatively inexperienced electronics hobbyist and have am
    looking for a rf circuit to fit a certain need.

    What I'd like to have, is simply one circuit(a) which will emit an rf
    frequency, and another seperate circuit(b) a few feet away, to detect
    circuit (a)'s transmission.

    Basically a very simple remote control, press a button on one circuit,
    and have it effectively turn something on in another remote circuit.
    Also, the smaller, and simpler the better.

    Any help will be much appreciated, thanks a lot.
  2. Try the "Digital Wireless for the Bench Top" link here:

    Another way you can go is to buy a matching pair of RF
    transmitter/receiver boards, like these: Link Wireless/TLPRLP434A.pdf

    You can get them at The transmitter and receiver will
    cost about $14.
