Frank, My feeling is that for a mobile, we should strive for a balance between a totally new way of doing things and what the end user may be familiar with. Most, if not all, current mobile radios can be tuned from the microphone as well as from the dial on the front, so this should be where we focus the coding for the input; direct frequency input from a touch screen is a good thing to add in a "firmware" update. Developing the mobile version first also has the benefit that what we add to it can reduce the work needed on the software side of developing the handheld version.

I would like to caution against going for a touch screen user interface. I have worked on such writing touch GUI framework code for years, and the complexity of making a good touch UI should not be underestimated. The work involved will also detract significantly from the development effort needed for just a working SDR radio. My advice would be to aim lower in the UI look and feel, but still a little higher than the current mass marked radio. Ex colour screen 320x240, fixed bitmap fonts. Directional navigation key, numeric keypad. Menu driven UI, with some nice widgets (waterfall etc) Most importantly, there needs to be a very very clean separation between UI code and the radio layer, (event driven), such that a touch UI can be added later without having to do major changes to the radio layer.
