[Elecraft] Strange problem with K3s/10: could use some suggestions

[Don Wilhelm]

Bill,

Are all your antenna connections tight? - finger-tight is frequently 
not enough for SO-239/PL259 connections, use pliers to tighten them a 
bit more than finger-tight (after making sure the PL-259s are seated in 
the "notches").

I would suggest doing the TX CAL procedure once again.
If that does not correct it, contact K3support for further assistance.

73,
