George,
I don't know the accuracy of your frequency counter, but that accuracy
statement is with reference to the frequency of the reference oscillator
(almost 50 MHz), so that accuracy must be better than 0.5 x 10 exp8 or
0.02 ppm. Check the specs on your counter to see if it is sufficiently
I am installing a TCXO for my K3 and the manual say's:
* METHOD 1 (Frequency Counter):*
* Locate the *CONFIG:REF CAL *menu entry.
* Connect a frequency counter with +/-
*1 Hz or better *accuracy to J1 on the reference oscillator
module. Measure the exact frequency in Hz.
* Using VFO A, set th
