Dave,

Have you read the information in the "Circuit Details" section of the K2 
manual?  It contains a good description of  the synthesized VCO operation in 
the RF board Sheet 1 section.  That information coupled with a careful study 
of the schematic should give you the operation details that you request (the 
DAC sizes are indicated in the schematic, so you can extrapolate the step 
sizes from that info).  I am not aware of any documents that elaborate 
further - the code in the firmware that drives all this 'magic' is Elecraft 
proprietary.

73,
Don W3FPR
