One watt wouldn't be a problem at that distance, but any frequency this can operate on requires line-of-sight or close to it. "Several miles away" might be realistic in the middle of a desert, but in areas with hills or lots of large buildings? Not likely.

Generally speaking, line-of-sight is almost always what limits point-to-point comm range for handhelds, rather than raw power. On higher frequencies, even vegetation can be a big deal.
