[Elecraft] K2: KAT2 null adjustment

[Peter Wollan]

According to the manual, it should be possible to adjust the null to
000, and it should be a broad null.  On mine, it was extremely sharp,
and wouldn't get lower than 010, flickering to 011.  Does this indicate
a problem?  I went ahead and finished the installation -- the voltages
were fine, and the tuner seems to work just dandy.  

I'm using a homemade dummy load, which seems to test out ok at least at
the lower frequencies, and I don't have a calibrated wattmeter (yet,
will borrow one soon).  

Can/should the null be recalibrated, even though the resister has been
installed?
