difax mailing list is no longer active. The list archives are made available for historical reasons.
Just my 2 cents worth about difax -- similar to what Larry is doing, we ftp the difax charts in tiff format from the nws site. We do this from a vax system, but using cron would give the same results. I have a separate file for each time, retrieving only the charts that should be ready at that time. These are then stuck on a shared directory on an nt machine and we use an image viewer to look at them. We archive them on the vax in case we want to go back. The viewer allows printing if needed, and magnification -- the images are pretty sharp. So as long as NWS makes them, we will continue to grab them. And this is free. Frank Colby UMass Lowell
