    Hi,

    Im doing my project, trying to send a signal from the "HT12E encoder" to a
    "HT12D decoder" ........... The problem is that i've been told that the
    oscillator frequency on the transmitter and the receiver needs to be the
    same is this true!? i have had a look at the data sheets and it dosen't
    seem possible am i missing something??

    Any advice on this subject would be a good help thanks, this is my first
    time constructing something practical from the theory that i have learnt and
    it is proving challenging in a good way though....

    According to the Holtek datasheets and faq, the frequencies are different. The transmitter (HT12E encoder) should have a frequency
    50 times that of the receiver (HT12D decoder).
