    so it should be possible to send data only to a designated receiver module?
    Yes and no...
    When data is sent it is sent everywhere. It is up to the receiver to "decode" the signal. Even data that the receiver does not understand hits the receiver.

    Think back to serial comms with wires. You have a "wait" for something before the receiver acts on the data. Pretty much the same with RF. But with RF there is noise from everywhere hitting the receiver.

    Will do mackrackit, thanks for the info. My RF knowledge is less than my LED knowledge when I first came here right now......oh dear.

    The Modules arrived today (I only ordered them yesterday) they came over from Belgium too. They are quite small (I was expecting them to be larger, I don't know why). I'll have a closer look when I get a minute / tonight.

    RF is the 'Holy Grail' for me. If I can figure this one out then it's uses are nigh on endless.

    Problem?:

    I'm thinking I should have ordered the: "rfPIC software and complete documentation (on CD)"?

    There was no CD in either of the boxes. I'm thinking I'm up the creek without it? Or can I get by without the CD?

    Sorry I know, more questions.

    This might be a place to start

    I have not used the rfPIC modules but I think we can figure it out.

    A quick look at the data sheet.
    Header J3 in the PICKIT1 needs to be used after removing the chip from the evaluation socket. My PICKIT1 just has holes for J3, if yours is that way you will need to bring wire off it to a bread board. Looks like J3 pin#1 is on the edge of the board.

    Then after the module is programed it should be able to "stand alone" on the bread board.
