I'm picking up the thread a few days late. Asidefrom the contesting and
rare-DXing, there is a whole world of plain old morning or evening QSOs with
friends that, because of seasonal changes or propogation fluctuation, when
the linear makes for comfortable QSOs. In the phone patching days the
linear was also a great help. These are sort of routine cicumstances where
an amp makes life enjoyable.
