KPC2.2
The NP0 designates a zero temperature coefficient which means there 
should be no change in capacity with any change in temperature.  
Other types may work fine, but accuracy versus temperature may be 
a problem.  Other users may find the 47 pf capacitor too small 
(clock still runs too fast) or too large (clock now runs too slow) 
for their particular TNC.  Use of other values may be necessary in 
these cases.  As long as it is possible to get the software clock 
within adjustment range of the DAYTWEAK command, final corrections 
may be made using the DAYTWEAK command.

I hope this is of help to KPC-2 users if they find this a problem.

I have seen this situation in two KPC-2 TNC's so far and wonder if 
it is a widespread problem.

If anyone has any questions, please don't hesitate to contact me via 
the K3MC BBS in Pittsburgh, Pa.
