There is a good list of time signals on the web site of the BIPM:
http://www.bipm.org/jsp/en/TimeFtp.jsp?TypePub=scale#nohref
in the "Time Signals" in the Scales division of the FTP server of the Time,
Frequency and Gravimetry section. The most recent is dated 2008.

Marco, have you considered that HBG on 75.0kHz might be stronger with you
from Switzerland??. In a lab or other complex quite often with off-air
standards the problem is local noise. I have a friend in Porto who used
to
be able to lock to MSF when it was at Rugby a few years ago.......I
havent
asked since it moved north to Anthorn but I suspect he uses GPS now. If
the
noise is not a problem these receiver will often work well on a resonable
wire antenna which is fairly easy to rig. Or see the PA0RDT MiniWhip
design
for a very simple active low frequency antenna. This is used all round
the
world for receiving weak amateur signals on 136kHz ....it is broadband up
to about 500kHz, and down to 40kHz Japanese frequency standard
transmissions. It is so small you can experiment to find the best quiet
position. At LF the secret is the higher the better.
I may very well be mistaken (and do hope so indeed), but isn't HBG about
to be
shut down quite soon? Maybe that i'm mixing that one up with another one
though.
BTW, is there such a thing as a comprehensive page on frequency standard
transmissions on the web? That Japanese 40kHz sounds quite interesting...
And as far as i recall, reception of those LF signals is supposed to be
better
at night as there probably is less man-made noise and better propagation.
HTH,
Florian
