To Trouthbridge: ohoy that was a good debate. Thanks all for this analyze and to WhipperSnapper who have been monitoring my project from another Forum as well + Troutbridge: I go for your advices; why should i become a radio amateur at my age (57)having no time for all that incl not only comptence but also formal certificate? and yes - i think also you are both correct and also very emphatic to my situation! Maybe not the money has so much infludence for me as the simplicity and knowing that the right Sat system ( either 2 sat phones on the low orbit system or 1 Iridium) - i think i start to understand this and also what you already pointed out:
Also WhipperSnapper: You use it all and have the experience obviously + gives clear and friendly info: Yes its sound to get the adequate for the NOW. Even if I some time even go around the world - upgrade for that IF IF and IF that ever happens, ( probably it will be the system covering almost the whole trip from Africa to Carribean)
