This is to support a previous suggestion on the reflector, to allow locking the 
P3 frequency range displayed despite tuning the K3.  The defacto mode of 
draging and skewing the waterfall makes it unrecognizable, losing track of and 
tune to a new "target" QSO up the band.   It would seem much easier if tuning 
the K3 just moved a marker across an unmoving P3 display.  My thoughts are 
towards operating next Field Day, where I might set the P3 to display, say, 
7.025 through 7.075 KHz.   

Of course there would need to be a provision for "re-centering" the P3, most 
likely to a round number, not the actual K3 frequency.  For example the P3 
could re-set its center to the nearest frequency marker at the top of the the 
P3.  As an example, assume a P3 set to a span of 50 KHz, where its 10 markers 
at the top would then be spaced 5 KHz apart.  Assume a K3 is tuned to 7.048 
KHz, and the "re-center" button is pressed.  Consistent with the suggestion, 
then, the center frequency of the P3 would snap to 7.050 KHz, and display a 
span from 7.025 to 7.075 MHz.   

Besides the pile-up value another post suggests for this mode, I see it equally 
valuable for contests and for looking for an ongoing QSO.
