[Elecraft] K3 A/B button problem

[Steven.Zabarnick at notes.udayton.edu]

I'm seeing an intermittent problem with the A/B button on my K3. When I
have VFO A and B set for different modes and frequencies, pressing the A/B
button sometimes copies the frequency from VFO B to A after exchanging
them, rather than exchanging them only (the mode is not copied). The
problem never occurs when the mode is the same between the two VFO's. Has
anyone else observed this? Does the fact that the problem does not occur
when the modes are the same, imply that this is a firmware rather than
hardware issue? My K3 does not have the subreceiver.
