    Hi, I am attempting to do the test for the Ht12-D and ht12-E. I am not getting anything in the LED's. I am getting voItage from pin 18 to pin 9 on the encoder, but no voltage from 18 to 9 on the decoder. I have switched out all components to check for bad components. Is there somewhere I could send a photo of my circuits to be checked?

    in transmitter circuit there is some mistake written in Antenna circuit :
    DATA
    VCC
    GND
    ANT

    please correct as

    VCC
    DATA
    GND
    ANT

    kindly note and correct in your wiring diagram otherwise circuit will not be operative.
