[Elecraft] K2 #4472 new builder question on 4 mhz alighment

[Masleid, Michael A.]

Hi Jerry,

>What do I adjust ? If i adjust C22 nothing changes.

C22 and the 4 MHz oscillator is used when you calibrate
the K2.  First you set C22 using CAL FCTR, then you run
CAL PLL and CAL FIL so that the MCU can learn about the
BFO and PLL reference oscillator settings by "comparing"
those to the 4 MHz oscillator.

The rest of the time, C22 and the 4 MHz oscillator is not
used as a reference oscillator, so nothing happens when you
change C22.

You can set C22 using CAL FCTR, but you have to run
CAL PLL and/or CAL FIL again in order to make any
change in tuning.
