[Elecraft] K2 #2555 on air! couple of questions...

Tue Apr 23 08:53:00 2002

Are you trying to calibrate your K2?  If so, you have to set the frequency
counter probe to TP1, set CAL to FCTR and then you observe changes at around
14913.88 KHz.  The procedure is found on page 98 of the manual (I have
#1299).  Remember to run CAL PLL and to change from and then back to your
CAL FIL  settings!

It's a relatively ungainly procedure just to calibrate the durn thing, but
it works and the rig holds its calibration quite nicely.  And, yes, WWV is
supposed to be on 10.000.000000 MHz exactly!  (Also 2.5, 5.0, 15.0 and 20.0
MHz, I think).

73,

Joe, W2RBA
