...site, however, 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: https://www.u-blox.com/sites/default/f...

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 one) using zip drives or similar (cdroms, etc), since modem lines are quite slow and expensive (in Italy). I though I could produce the "signature" of files on home computer, store it on a zip, go to job, run rsync to copy the missing or altered files on
