Hello,
Looks like you have done some homework here. The
kenwoods have 5, 10, and 50 watt ranges.  The problems
folks will probably have is to make the choice between
mid and high power when on the road.  I use the 10
watt setting where I am.  It is enough as there are
two digis in my area of travel that get most of my
packets.  I wish there were two more but that is a
story for next spring when I may have another digi on
line.  

Merry Christmas,
Chris
