The KIO2 uses a crystal frequency of 16.289 MHz. It has NOT been  
changed since the unit's inception. The KRC2 uses the same crystal.

The KPA100 has a voltage generator that uses an 18.432 MHz crystal.  
This one _has_ been changed since the original kit. The original  
frequency was also 16.289 MHz.

It might be interesting to change the KIO2's crystal to 18.432 to see  
if the spurs you are encountering go away (or get moved to somewhere  
less interesting).
