I am preparing an expedition to YO-la and am in doubt about which radio to carry with me. The three candidates are a Yaesu FT-897D, a Yaesu FT-857D and a Yaesu FT-817ND. Each one of them has its own advantages. The FT-897 is the most powerful, because it can give its full output of 100W with the YT-100 antenna tuner, and the FT-817ND is the lightest. The FT-857D is in between, being able to work at 60W with the SG-211 tuner. What do you think?
