[Elecraft] Strange K-3 Behavior in TX Data mode

[Dave Fugleberg]

Pete, I have seen similar behavior from time to time when I use WSJT-X, but
cannot pinpoint the trigger for it. In my case, the display on the K3 shows
the maximum bandwidth, but if I manually adjust it with the Width knob it
is actually very narrow- it takes several turns of that encoder to widen it
out to 4KHz.
Try cranking on the Width knob, even if the display on the K3 looks
correct- does it help?
