    Sounds like a weak battery or the transmitter was stuck on transmit.
    I'm hoping the former.The battery I used was unopened but had been my draw for a long, long time.

    Can you check the amps when "not in use" ?
    Tricky and I guess I'll need a new battery which I don't have right now. I guess try a new battery.

    I read in the TX pdf that the TX output power can be set and adjusted via different resistor values set on a pin. This might be a way of increasing the transmit range (at the cost of battery power/life I guess).

    Here's (another) project I'd like to do next Spring (gives me time to learn how to do this). Most Years we have birds use a nesting box in our apple tree. When the young hatch, the parents are really busy bringing in food. I'd like to:

    1/ Have a beam set across the entrance whole to the nest box.

    2/ When the beam is broken (parent bring in food) a counter is incremented and stored.

    3/ Set a Light_Dependant_Resistor up so that when night falls the days DATA is rfpic'ed back to the RX module and displayed on the Serial Communicator.

    LEDave, so many projects, too little knowledge.

    Cool project!!!
    Two beams so you only count one way? Or just divide by two?

    Mmm, I hadn't thought of that. I guess divide by two would be easiest, all depends on space I guess.

    Looking at the TX / RX demo code in.ASM it looks really difficult and Bruce's code not much easier, although I can understand some of that, would be good to try and figure and learn over the Winter.

    To my mind, sending data through the air has something mystical / magical even about it. I'd like to crack rf.

    Right, I'm off to me bed.

    Night, night mackrackit.

    You will get it.. Plenty of resources here.
    But you may want to start a new thread specific to the project. This one has gotten all over the place...

    Would be go if I could. Like I said when I first joined the Forum: I may not be that brightest but I am a trier

    Fair comment mackrackit. I'll do my background research into rf and try and pick up as much as I can then later in the year I'll start a 'Project Specific' thread.

    In the meantime what next here?

    Same here, I just add more voltage though...

    While you are getting the RF modules figured out you could start on the project using wires.
    Then all you will have to do is add the RF stuff later on.

    Good shout, I like it and I'm on it Boss

    I'm thinking two 16F684's SEROUT from one into SERIN on the other to LCD / or Communicator. With a push_button on SEROUT PIC to simulate the beam at this stage with an LDR / potential divider to trigger the 'SEND DATA' at night fall.

    How does that sound?
