QUOTE: "DCF77 marks seconds by reducing carrier power for an interval beginning on the second". UNQUOTE This is not a good (Heaviside step) time marker.
The amplitude is carefully crafted to signal and transmit antenna.
Is it possible to decode that signal by any very simple "on-my-shelf gear", as for instance a PC sound card,to recover a good seconds time mark? Do you know some software to perform the above task?
You need a wide-band sound-card like EMU0202 and SpectrumLab. This software contains the needed tracking software. A simple JFET or low-noise OpAmp as preamplifier for a 1 metres wire-antenna.
