[Elecraft] K2 RF Board Test II

[Don Wilhelm]

John,

This is the normal behavior is the proper VCO values are not entered into
the EEPROM.

If you have not yet run the CAL PLL procedure, that is explaination enough.
If you have run CAL PLL, put the bottom cover on and re-do it.

If you then still have trouble, we can help with detailed troubleshooting of
the PLL and VCO areas.

73,
Don W3FPR
