[Elecraft] K2 PSK offset

[John Wiener]

I am noticing a slight drift over several months in my PSK such that my xmit doesn't match my rcv.  It is off by about 10 or 20 Hz   ...   just enough for missed QSO opportunities.  Also, there is a slight (10 Hz) shift between FL1 and FL2
I am re-reading the CAL FIL notes.  

Should I recalibrate or is there another way to more accurately match freqs?  Also, I am guessing I should use the table in the KSV2 manual.
