dunnd1,
My guess for the lack of response is that few people, if anyone, on this board have the skill set that you have in communications. I've seen a few posts about people using SAT phones, but they sound expensive. Some people have also claimed to get cell phone reception in a few spots. And finally, some people intentionally do not want to be able to communicate electronically with the outside.

So unfortunately for you, I guess aren't going to get a lot of help on this one. :-[
