That looks great to me (again allowing for the Elecraft=20
design compromises).

Here's a silly question - has anyone ever checked their
K2 at each ends of the trimmer's range? In other words, if
you didn't even try to do it right, how far off could you
be? (Doing CAL PLL after setting to the end.) What's worst-case?
