Hi Al,
The VFO tuning of the K2 is drivin by its low phase noise PLL and a
lookup table (created by CAL PLL) as well as the values stored for the
BFO settings (CAL FIL). Therefore, after adjusting the 4MHz oscillator
via C22, those routines must also be run as they depend on the new
crystal

Al,
The C22 setting does nothing to change the K2 display - you must run CAL
PLL and CAL FIL (for all filters) before any change in the display takes
place. Normally, the reference oscillator only serves as a clock for
the MCU - the frequency display does not depend on it.
