All, I forgot to say that when I wrote about not having satellites displayed, I meant that if I type "observ 1" I get plenty of observations displayed every second, but if I type "satellite 1", then I get usually no satellite mentioned, sometimes 1 or 2, and very seldom what rtknavi displays at the same time from the same str2str server (and when that happens I do get a solution, but very seldom).
