Yes, that is exactly what I understand now. The GRANULARITY of the display
is higher or lower depending on the s;oce of bandwidth selected and
displayed on the screen. The narrower the slice, the smaller the
granularity. I thought the P3 was like the old fashioned external VFO units
that took over the frequency generation on the rig. It is not, its just a
read out.
I'm straight on this now. Shouldn't try to multitask too much at work :)
Not enough cycles delegated to groking the information.

Lu,
I don't think the accuracy is a problem, it is the rounding of the frequency
that is displayed on the P3 - that is simply resolution of the frequency
indicated. At least that is my understanding from a perusal of the P3
manual.
The screen is continuous, but a frequency of 7035.265 displayed on the
K3 will be 7035.3 on the P3 In fact, any frequency between 7035.250 and
7035.349 will show up on the P3 as 7035.3 If there are several signals in
that 100 Hertz span, you should be able to point to one of them and click -
the K3 should show the low order digits, the P3 will not.
73,
