I would point out that even for a sighted operator, a touch screen would =
introduce some efficiency issues as well. I know ops who will log with =
one hand while making adjustments to the rig with another. I believe it =
would be possible to combine touch screen technology with some knobs and =
buttons. I cannot imagine anyone wanting a radio that has only a touch =
screen. This might satisfy some, but I think that segment would be much =
smaller than the overall population.
