The K2 Manual, and various posts to the Elecraft website or this
reflector, provide substantial information regarding K2 adjustment, c22
calibration, filters, etc. These generally assume that one doesn't have
access to test instrumentation beyond a DMM and the frequency counter
built into the K2. This is laudable since it has allowed me, and many
others, to build and calibrate a K2/100 without investing in an
electronics lab. However, I have been slowly accumulating good test
equipment to pursue various design and repair interests and will soon be
going over my K2/100 and my KX1 using these tools. It would be helpful
to have adjustment and calibration procedures available that
alternatively assume the use of test instrumentation. Although one can
admittedly figure a lot of this out yourself, having a procedure/check
list reduces the possibility of error. And in some instances, the
sequence of adjustment can be significant.
Since potential purchasers might be put off by reference to "set the
spectrum analyzer to...." the alternative calibration procedures could
be available on the website with the primary calibration procedures
(those currently used) being contained in the manuals. This would
reinforce the concept that the K2 can be successfully built with a
minimum of equipment.
