[Elecraft] K3 + P3

[Alan Bloom]

The rule is that when you turn a marker on it is at the same frequency
as the last time it was on, unless that would put it off-screen.  In
that case the marker comes on at the center frequency.

The same thing happens when you change bands.  The marker will appear at
the center frequency.

There was an issue with band information from the K3 not always making
it to the P3 under certain conditions.  That was fixed in K3 firmware a
few revisions back.

If you hit the A/B key on the K3, then the old VFO B frequency is now
the VFO A frequency, which is where the P3 display will be centered.
The marker will stay at the same frequency it was before, which means it
probably moved on the screen, assuming VFO B had been on a different
frequency from VFO A.

There was another issue in K3 firmware with sending updated A/B info to
the P3.  It is fixed in the latest field-test firmware which should be
released for beta soon.
