[Elecraft] K2 and NaP3 IF offset values

[K8AC]

I suspect that the difference I saw in the offset for 20M was indeed due to a
different filter selection.  If I center the signal on the NaP3 indicator
using my most-often-used 400 Hz filter, advancing through subsequent
narrower filters I see just a bit of movement of the signal relative to the
pointer.  But, with the two wider filter positions, the movement is
substantial and would require a much larger or smaller offset in NaP3 to get
the signal aligned with the pointer.

With a bit of work, I can probably get the signal and pointer pretty much
aligned by tweaking the BFO settings for the wider filters.  I'll watch the
shape and position with Spectrogram while doing that.  

By the way, this isn't just an academic exercise.  When I'm operating split
and chasing DX, I often need to be able to position the transmit VFO pointer
on a signal and have the K2 exactly on that frequency and not a couple
hundred Hz away.
