Thanks everyone who responded to this. I checked my calibration as
suggested and believe it was, indeed, about 50 Hz above actual. I'll
test with some live spots.

For spots, please use your favorite
"retail" DX cluster.

Ever since I have owned my K3, I have noticed that most spots put the
K3's receiver above the actual frequency of the spotted station.
Initially, I thought this might have to do with DX spots being rounded
to the nearest 100 Hz, but then I realized that, if that were the
case, X percent of spots should be high, X low, and Y (whatever
percent) effectively right on.
I've checked the K3's calibration, and it appears to be right on at 10
and 15 MHz, tuning in CW mode to WWV's carrier at my preset beat
note. One possibility that occurred to me is that perhaps the DX
cluster convention is always to round up, rather than up or down.
Seems a little unlikely to me, but does anyone know the answer? I'm
perfectly happy to keep jogging the main tuning knob a bit on most
spots, but thought I'd ask.
