[Elecraft] K3 SWR Accuracy - reprise

[Dave G4AON]

Wayne (and Jack) I and at least one other user, have noted the K3 with
ATU sometimes appears to leave a residual C or L in circuit on 10m when
in "bypass" giving lower than expected power into a 50 Ohm load and may
give incorrect TX power calibration as a result. Using the ATU to give a
good SWR fixed the problem. The residual issue isn't always there, the
typical false SWR is 1.5:1 or 1.6:1.

--------------
We'll post additional details soon. Meanwhile, no one need worry about
this apparent discrepancy. The ATU is cancelling its own strays, and
the SWR bridge is correctly reporting the load presented to the
transceiver internally, which is the important thing when matching the
rig to its load.
