WWVB is currently running at half-power (35KW ERP; 75.45dBm) so cut the
available power in half at the moment.
However, WWVB's signal _is_ 60kHz, and so any building of metal
construction, even sparse-spaced rebar in concrete, will effectively be
a very high attenuation 'waveguide-beyond-cutoff' attenuator, and so a
very effective shield, even with the very high power available to the
receiver.
GPS receiver module manufacturer u-Blox has an informative paper on GPS
receiver antenna design that might answer some other questions:

offline rsync
hello, I'm new to this list.
here is my question:
I would like to synchronize two computers (say the home one and the job

quite slow and expensive (in Italy).
I though I could produce the "signature" of files on home computer, store
