To me, span and scale are different. Span is the number of units between two 
points, scale is the physical size those end points cover.

Consider a map of the U.S. The span is 4000 miles. It's printed on a piece of 
paper the size of a postage stamp. You don't see much detail. Now consider that 
the same map is printed on a piece of paper 8.5 by 11. The span is still 4000 
miles but the scale has changed dramatically, and now you can see some detail.

I'm rarely if ever interested in what's happening on both sides of a given 
frequency, just usually up the band, less often down. If the paradigm was edge 
to edge rather than center to edge..

Thanks for the discussion, Alan. I've deduced that the answer is no.

On the P3, span is the number of units (Hz) on the X axis and 
scale is the number of units (dBm) on the Y axis.

The rig is at 3.524. I double-tap the Split button to equalize the
VFOs, then hold Split. The P3 is set to a span of 10, i.e. -5 appears
to the left, +5 appears to the right. I set the P3 to tracking mode
and move the green cursor to the left edge of the screen.


I assume you mean you use the CENTER control to move the center 
frequency up 5 kHz so that the VFO A (green) cursor is at the left edge 
of the screen.  At this point the left edge of the screen is at 3.524 
MHz and the right edge is at 3.534 assuming the span is still 10 kHz.



What I'm looking for is that when I tune either the B VFO or the B
marker up band, it reaches the far right edge of the screen when I
get to 3.529, instead of reaching 3.529 when it gets just to the
right of the screen center.


To do that the span has to be 5 kHz.  (3.529 MHz - 3.524 MHz = 5 kHz)


In this set-up moving the B marker moves the A & B cursor and the
marker and changes the center freq. displayed on the screen. That
isn't desirable.


I don't understand that.  Moving VFO B or either of the markers (A or B) 
should not cause the center frequency to change.  That only happens if 
VFO A is moved.  (Tracking mode)



I don't want to change the span, just the amount of real estate it
covers.


But the span IS the amount of real estate that the screen covers.  It is 
the difference between the frequency at the right edge and the frequency 
at the left edge.


Sorry, I'm probably still missing something.  :=)

I'm not doing a a good job of explaining I think.

The rig is at 3.524. I double-tap the Split button to equalize the VFOs, then 
hold Split.
The P3 is set to a span of 10, i.e. -5 appears to the left, +5 appears to the 
right.
I set the P3 to tracking mode and move the green cursor to the left edge of the 
screen.

What I'm looking for is that when I tune either the B VFO or the B marker up 
band, it reaches the far right edge of the screen when I get to 3.529, instead 
of reaching 3.529 when it gets just to the right of the screen center.

In this set-up moving the B marker moves the A & B cursor and the marker and 
changes the center freq. displayed on the screen. That isn't desirable.

I don't want to change the span, just the amount of real estate it covers.

In tracking mode, if you set the span to 5 kHz and adjust the CENTER 
control until the VFO A cursor is right at the left edge of the screen, 
then it will display from the VFO frequency to 5 kHz above it.  As you 
tune the VFO you will always see 5 kHz just above the VFO frequency.

Re: [Elecraft] [P3] Can I?

[Mike Reublin NF4L]

Thanks Alan -

I'm still at sea about the span. With the A cursor at the left edge of the 
screen reading 14.022.5 the span icon on the right shows a +5. If I tune higher 
with B or B marker, I hit 14.027.5 a little to the right of the physical center 
of the screen. 

So is there a way to have that almost full screen from the A cursor on the left 
edge to the right side of the screen cover 5 KHz? It sure would make it easier 
to find the sweet spot in the pileup.

[Elecraft] [P3] Can I?

[Mike Reublin NF4L]

Span is set at 10. When chasing DX split, is it possible to position the VFO A 
cursor at the left edge of the display and have the right 5 kHz expanded over 
the (almost) full screen?

In trying to achieve this, I got it so that when in tracking mode the A VFO 
moves the magenta cursor as well as the A & B markers. The B VFO also moves the 
magenta cursor. The green cursor doesn't move. Is this working as intended?

Re: [Elecraft] [P3] Can I?

[Mike K2MK]

Hi Mike,

This really works best in Fixed Tune mode. Just hold the CENTER button and
turn the SELECT knob until the VFO-A green cursor is at the far left. It
will stay put as long as you don't move VFO-A on the K3. The VFO-B (magenta)
cursor (and the split red cursor) will move as you tune the VFO-B knob on
the K3. If you also want to use the A and B markers they will follow the
select knob on the P3.

73,
Mike K2MK

Re: [Elecraft] [P3] Can I?

[Alan]

Of course in fixed-tune mode the screen always displays the same fixed 
frequency range -- as you tune the K3 VFO, the cursor moves across the 
screen while the displayed frequency range remains the same.


In tracking mode, you can offset VFO A to the left side of the display 
using the CENTER control.  (You have to have enabled the CENTER control 
using the CenterEn menu item.)


Once you do that, the VFO A cursor will remain at the same position on 
the display as you tune the VFO.  If you have the display set up to show 
(let's say) -1 kHz to +9 kHz from the VFO frequency, it will continue to 
do so.

Re: [Elecraft] [P3] Can I?

[Rick Prather]

Mike,

As far as I'm concerned that is a "killer feature"  of RUMLogNG.

On the P3 control panel clicking the left portion of the VFO A window puts
the cursor where you want it.

I have come to really miss that control screen if I happen to be using
another Logging/Control program.
