P3 - waterfall suggestion
Locked
 
|
The P3 waterfall works just like all others I have seen and used: when you
tune to radio, the "old" pixels continue to move down the screen vertically, but do not move horizontally with the tuning. As a result, the waterfall is useless until it catches up a couple of seconds later. If those pixels all moved horizontally with the tuning, then the waterfall would still be relevant and helpful in tuning to a signal of interest. It's "only" software. By the way, what a totally enjoyable addition to a great radio. Way to go, guys.

This is the normal behavior of all waterfall displays I've seen, and
is a very familiar screen behavior. The cursor is the means of zeroing a signal of interest which then telegraphs the new frequency back to the K3. Part of the issue of tuning is that the saved information does not include frequencies outside the display, so tuning as you suggest would require filling in zeros all the way down AND further, performing a second graduated shift of ALL information. Given the very fine degree of detail stored, this may be a significant CPU intensive task using up processor cycles. Devil will be in the details, not in the simplicity of concept. 73, Guy.

The Fldigi program follows the behavior Glen requests and is what I'd also expect to see when tuning. 73, de Nate >> -- "The optimist proclaims that we live in the best of all possible worlds.

And uses the resources of a PC to present it?

I would not expect any new information outside of the starting display
... Black on the edge would ok until filled in from the top. I just think that would be a much more useful dislay when tuning from the K3 as an alternative to marker QSY.

This has been talked about during field testing and has been
considered. There were no promises but once things calm down they may have time to get to something like this. ~Brett (N7MG) On Fri, Aug 20, 2010 at 2:12 PM, GLEN BROWN <[hidden email]> wrote: > I would not expect any new information outside of the starting display > ...
