I think that the accuracy will never be sufficient for this kind of

I think you must make the comparation, but not whith the Conrad Clock. You
musk take the pulse make from the RF signal in 77,5 KHz.
Marek and Manuel,
thanks for your comments. You are both right, of course, but my main
goal wasn't that of
using the 1pps signal to discipline an oscillator. For this I will use a
GPS as soon as I will
have installed the antenna on my roof. I tried here in the basement,
but, as sensitive as the
antenna + receiver may be, absolutely nothing :-)
It was more of a "divertissement", I just wanted to check the accuracy
of that timing.
Seeing that it varied slowly around a central point, I thought (wrongly)
that the cause could
be attributed to the ionosphere. Now I know better...
