Alan,

I have the same issue; mine is off about 50Hz.  Not a huge deal but just enough to be annoying on VHF SSB and CW.  I do have the REFLOCK, EXTREF (10MHz GPSDO) and KTCXO-1; nothing left to add.  You are correct that you can’t adjust the offset once you’re in this configuration.  As I say, for me its “only” about 50Hz but its consistent.  I was gonna have to Elecraft team look at it in their lab the next time I send the rig in (if I send it in).  Aside from that I’m living with the 50Hz delta.
