Today I received a lot of satisfaction with the time signal DCF77 from Mainflingen near Francoforte.Il signal is the frequency of 77.5kHz and its reception I used ferrite antenna (auto built) made up of several bars of iron, joined together to form one large bar dimensioni.Su this bar, I then wrapped a coil around 800uH connected to a capacitor 5.2nF.Così made, this antenna is tuned to resonant frequency of 77.5kHz.
To the output jack I wrapped a child that I connected directly to the receiver. Under
carry a screenshot of the program I used to decode the signal.
The program is called "Clock" and is an additional tool of Multipsk.
also shows the video that shows the program in action during the synchronization signal orario.Ho removed the audio from the video because correttamnete has not been acquired.
I recorded the audio separately and enclose it in video format below.
