[wt4hq] GPRS

[Mikael Larsmark]

Hello!

I just tested with a small network of computers (just four of them) with 
GPRS and it seemed to work fine, so far.

If one would disable the SYNC option in the UPLOAD where you can 
configure the network interface on the GPRS station and the GPRS station 
loose connection for a while, won't the QSOs be uploaded to the other 
computers when it comes back online then?

And if as you said some computer breaks during the contest and it is 
replaced with a blank log, would that computer not get the QSOs from the 
GPRS station with SYNC upload disabled? Or would it get the qsos from 
one of the other computers, that are connected with broadband?
