[Elecraft] K3 filter presets I/II: present and future functionality

[wayne burdick]

Do you find the DSP/XFIL filter presets, I/II, useful? If you haven't 
tried them yet, please do. Here's the short version:

In each mode, there are two presets (you can also think of them as 
"configurations"). Each preset is just a combination of DSP settings 
and the corresponding automatic crystal filter selection. They're 
intended to be set to match the present operating situation. First, set 
up preset I the way you like it, then switch to preset II and do the 
same. From then on, you can go back and forth between them. For 
example, you might want narrow and wide settings in CW mode. Or in SSB 
mode you might want one setting that's normalized to the 2.7 or 2.8 kHz 
crystal filter, and another that's shifted down and narrowed somewhat.

Our firmware field testers have suggested a different way of using 
these. Rather than have the presets "float" (change every time you move 
the DSP controls), they'd like to see them "fixed" (so that they don't 
change unless you specifically modify them via a menu entry, etc.).

This change is more significant than it sounds. Instead of having two 
freely-changing presets (configurations) that you go between, you'd now 
have just one working configuration. When you hold I/II, you would be 
loading either of the *saved* preset values into it. It would be 
similar to recalling a saved frequency memory which gets loaded into a 
VFO. Both the working configuration and the two saved presets would 
still be independent for each mode.

Before we make any changes, I'd like to know:

   - if you use presets at all
   - if you like the new proposal better (making them fixed)

This is the beauty of firmware: it's malleable. No need to keep 
functionality if it gets zero positive feedback.
