[Elecraft] KX3 Extended VFO temperature compensation procedure

[Phil Wheeler]

Reading the document on this, I get the impression 
that the procedure is done wholly within the KX3, 
because in the latter "post-refrigerator" part it 
says "If the KX3 is connected to a PC running KX3 
Utility, data will be sent to the Command Tester 
screen." implying the connection to KX3 Utility is 
optional.

Is connection to a computer required or optional?
