DCF77 sketch

Good day to all of you in this forum,
I am asking what is the most recent and performing sketch to decode the DCF 77 time standard ?
Where to download it ?

The main problem is the DCF77 antenna. There are good ones and bad ones.
Search at hackaday.com for "dcf77". For example this project : DCF77 Signal Filtering And Decoding | Hackaday
