[Elecraft] [K3] swr anomaly

[O. Johns]

Folks,

Did the Xmtr power alignment with utility version 1.2.9.30 and  
firmware version 3.44.  Used the BL2 balun connected directly to the  
Ant1 port of the K3, using only straight-through adapters and no  
cable.  The five watt calibration ran to completion and all was well.   
BUT, after the calibration, I find that pressing and holding TUNE with  
the ATU in bypass mode now gives a swr of 1.1.  Before the  
calibration, it always gave 1.0.  I know this is a small point, since  
1.1 and 1.0 are only negligibly different.  But it bothers me,  
aesthetically.

Anyone have any idea how to fine-tune the swr reading on the K3?  I  
recall that on the K2, you adjusted the balance to do this.  But on  
the K3?  Seems that since the K3 was aligned using the BL2 as its  
reference, the BL2 should show 1.0 swr.  Not so?
