One of the REALLY handy features for rovers is that it doesn't require
precision clock settings, there is no standard time cycle. That means if
I'm in an area with no cell service I can still jump on even if I have
clock skew.
Also, the version being released soon has a kill switch for right before
the June VHF contest. They don't feel it will be ready to go for this
contest season so it'll cease to function at the beginning of June.
