[Elecraft] Lock P3 frequency range independent of K3

[Doug Turnbull]

Hi All,
    This is an aspect of the Orion II which beats the present K3.  When one
tunes the VFO the display remains steady for a period of time and the cursor
moves across a frozen display in sync with the VFO.   Once one stops tuning
the VFO the display is no longer frozen.   It does help in manually tuning
the VFO rather than using the cursor to move to a different point in the
displayed spectrum.   I would like to see this change introduced.  Boy oh
boy a company which improves previously sold product!

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.

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.
