If I was going to carry anything, I'd carry a sat phone or maybe a PLB. Once you are out in the wilderness, radio reception will be sketchy at best. My feeling is that unless you have a base camp team that can relay weather reports to you by radio or phone, you aren't going to get a signal.

When I was in NZ, many of the mountain huts on the South Island had radios in them linked to one of the ranger stations. You called in every night to let them know how many people were in the hut and get the latest weather updates.
