[Elecraft] K2KSB2XTLS mod question

[Don Wilhelm]

Sam,

Use the K2 Dial Calibration article from my website - www.w3fpr.com (you 
already have it from my mirrored site).  I believe it has all the 
information that you need.  The procedure (in brief) is:
Skip to the filter alignment (part 3) first, and set up Spectrogram, 
then do a first pass alignment of the filters and BFOs - close is OK at 
this point, so don't be 'picky'
Now that you can receive SSB correctly, tune to 10 MHz WWV and set the 4 
MHz reference oscillator - use the N6KR method for best results.  Be 
patient here because the results depend on accuracy with this step.
Then run CAL PLL
After that, do a fine adjustment of the BFO frequencies - remember that 
you must move each of them even if they are correct.
You are done!

73,
Don W3FPR
