[time-nuts] T-Bolt Companion

Hello all! I am a proud owner o several T-Bolts. The last one is currently showing a comparison with the European LORAN-C chain 6731 (Lessay) sometimes better than 1E-12. Without any external temperature control. I feel therefore very happy. However, I need a good frequency divider/distribution

[time-nuts] DCF77 question

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. 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?
