A note on DeLorme wx: as I understand it, you have to pay an additional fee to get the weather reports. But the data is just NWS point forecasts. This ability will not be provided by the DeLorme trackers as provided by the RC. If you have a satphone, you do not need to pay for DeLorme/OCENS weather, as it is redundant. I don't think there is a way to get GRIBs or any graphic wx data using only the DeLorme.
This is why I plan to buy my own and pair it with a SSB receiver I am excited for the comm plans to come out.
