I have an Orion II to compare the K3 to.  When I receive the K3 (late Jan) I
will make RX comparisons.  I'm hoping that the K3 does not suffer from the RX
hiss the Orion II suffers when not connected to an antenna.

As to changing bands;  The only time I change bands rapidly is when using
cluster reports.  The remote control of modern rigs solves the band change issue
for me, so, although having band change buttons is more convenient it's not an
issue for me.

In addition the Orion II Main and Sub receivers are not synched well.  It is
irritating to set B to the frequency of A and hear the resulting warble caused
by the 6hz mismatch between the VFOs when listening to both.  I've never
experienced this on any other rig with two VFOs.  I believe the K3 doesn't
suffer from this issue.
