I am building an older QRP K2 kit ser. # 2438 Ver. A in
the Alignment and test section Part 11.  pg. 57,  the
PLL Ref. Oscillator Range  Test is out of limits.

The Reference High and Low frequencies are OK with
 readings (12100.53 high and 12089.43 low) with  range
 limits of 11.5 - 25  KHz but it is low, 11.1 KHz.
Is this a problem ?

In the PLL  troubleshooting section all readings are OK
except the BFO buffer output (0.025 -  0.070 VRMS )
 is slightly high 0.076 VRMS. Is this a problem ?

And lastly,
How do I visit the archives on this list ?

Thank you,

Jim / W1FMR
