[P3] Centering the cursor on VFO frequency ?

After the update that gave us the ability to shift VFO frequency without the spectrum changing, there are times that I want to recenter the cursor on the VFO frequency -- especially if I am using a narrow spectrum width in order to view the spectrum shape of a signal.

I can do this by pressing the Center function and using the knob to recenter the cursor.

But, I would like to do it with a single command button? Is there a way to do this? I have experimented but I can't seem to find a method that DOES NOT require me to manually adjust the cursor location using the knob on the P3.

Thanks for help or pointers to where I can read up on how to do this? So far, not found the right section if it exists.

73, phil, K7PEH

Pressing (actually holding) CENTER _twice_ will do it.

No, holding Center twice will center the *carrier.* If
one is in SSB or DATA A, the cursor will be offset to one
side of the display.

It is actually impossible to look at an entire SSB (or data)
signal with the span set to 3 or 4 KHz. I ran into that
last night ... I heard a badly distorted signal and wanted
to capture it full span width and it was not possible to
offset the "center" enough manually to move the carrier to
the left edge of the graticule.

Another way is to switch to tracking mode and then immediately back
again to fixed mode.

Re: [P3] Centering the cursor on VFO frequency ?

In reply to this post by Joe Subich, W4TV-4

OK, thanks Stephen. I did that and it worked -- just what
I wanted it to do (most of the time).

And, I do see what Joe is talking about that if the spectrum
is narrow and the cursor is as wide or wider then half of the
display that the center push twice does not do anything.

But, the knob dial does still work and allowed me to bring
my cursor into the center to see the whole spectrum of a
signal anyway.

So, I guess I will use both techniques. The double push when
cursor is narrow and the dial in with the knob when the cursor
is close to half the width of the display.
