[Elecraft] P3 suggestions

[Andy Faber]

Hi Al,
  I finally built my own P3 yesterday (#152) and it seems to work great. 
I'd like to revive three suggestions that I think I made earlier after using 
a prototype at P49Y in WPX CW.  These are all based on features of the Icom 
756 Pro 2 bandscope, that I think are desirable:
1)  Can a FN key be set to go to a preset span?  It would be very nice to be 
able to do so, instead of having to fiddle with the span knob each time you 
want to look wide or narrow.  How about allowing a cycling among several 
preset spans?
2) When one changes bands, it would be nice if the P3 automatically set its 
reference level, so it didn't need manual adjustment.
3) The Pro has a "hold" feature that freezes the display to allow you to 
move the marker to a signal that may have disappeared.  I realize to some 
extent the waterfall display allows that also, but it would be nice to be 
able to do so with the spectrum display also.
  As before, congratulations to you and Elecraft on a fine piece of gear!
