    I just made a trial with the software and tested it. Look what happens!
    I think you made some typing errors.

    Hi,
    if someone tried this code with dcf77.5 receiver buyed in Pollin.de store. The display show only message WAIT FOR STARTBIT and in the second row counter counts from 1 to 120 in the interval of one second.
    I use PIC16f876A and 4MHz quartz.

    Today I build a little buffer with CD4011 chip and now i got a readings of DCF77.5 signal but there is a one problem.Some times i have a correct decoded values of clock,day,year but mostly the values are incorrect,because of bad signal or lose of synchronization.Is it possible to make a routine in this code that checked whether all data is received in proper form and that there was no loss of synchronization.
