David,
On the frequency problem, order the no charge mod kit XV144MDKT from
Elecraft and install it. That will install a variable inductor in the
oscillator to allow you to pull the crystal into range (if not right on
frequency).
100 miles is a long distance on 2 meters.
You really need something to compare the receive with, the XV144 may be
working OK. It is really hard to tell whether it is working adequately
or not without doing some sort of measurement or comparison with a 2
meter receiver known to be working normally.
You should not normally have to turn the preamp in the K2 on, nor should
you need to turn the AF Gain up all the way. How high is that 11
element beam?
