[Elecraft] K2/100 Updated Chip Replacements

[Unifiedtx@aol.com]

The KPA100 manual states the need to do a realignment of the CAL PLL and CAL 
FIL due to the K2 Control Board U6 MCU and the KSB2 U1 updated chip 
replacements.  After replacing these chips I fould my Spectrogram patterns 
were not shifted enough to warrant making any changes, and the CW and CW 
Reverse offsets also remained correct.  The CAL FIL numbers changed only 
slightly.  I originally thought that by changing these processors I would 
lose all previous settings and would have to start all over again with a 
complete alignment.  This was a nice and very pleasant surprise.  I believe 
the CAL PLL and CAL FIL settings are stored in the Control Board U7 EEPROM.  
Thank you Eric and Wayne.   Roy Morris  W4WFB  K2 #2225
