[P3] Can I?

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?

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.

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.

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.

Re: [P3] Can I?

In reply to this post by Alan Bloom

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.

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: [P3] Can I?

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.

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.

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

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)

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. :=)

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.

Re: [P3] Can I?

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.
