Hi all! Finally I get my antennas mounted - had to instep the mast, which triggered a major rig service…
Now for the Atlantic crossing in late November I am looking for the right option/ data plan from Iridium. I have the Sailor 4300 setup. I plan on daily downloads of weather data/grob files, a few text only emails and the occasional short phone call. I have not the faintest idea what bandwidth and plan to aim for.

Also, shipboard electronics run on LINUX. So winlink does not seem to be s viable option. Has anyone tried (succeeded perhaps?) in setting up an automated position reporting script?
Thanks for any help and input/ recommendations

Hi Dick,
Good point, if one is getting a GRIB file for a large area just to understand the big picture of the weather systems, it doesn't need to be very large, if it is limited to simply wind & pressure with a long interval (ie 12 or 24 hours) between forecasts.
