Mike,
If you have the time to do it, I believe that it is well worthwhile arming
yourself with test equipment to do the job yourself. Although this sounds
like a tall order, most of the test and calibration equipment required to
check the K2 can be in fact be homebrewed, which obviously takes time but
saves $$ and which can be used when building other things. The ham
literature contains some designs which could be useful including at least
one for a spectrum analyzer and several low phase noise oscillators (QEX).
If you do go down this route, a pair of honest step attenuators capable of
60db or more attenuation over the required frequency range and into VHF are
critical items, I 'rescued' my 90 db step attenuators from a German
Standards Lab for peanuts. For the more 'difficult' measurements such as
receiver Input Intercepts where two or more signals are involved (ARRL uses
only two) various items are available from Mini-Circuits such as power
splitters / combiners which can be used to set up a RF test bench without
too much difficulty or cost, using double screened coax interconnections.
BTW I do not work for them!
I believe that the saying 'practice makes perfect' is applicable here, and
doing the tests oneself is interesting and helps to prevent future build
mistakes.

Subject: [Elecraft] K2 Alignment and Verification of Specifications
Does Elecraft offer an alignment and verification of specifications
service?
I'm sure many people would like to have their K2's aligned to "factory"
specifications and have those performance numbers documented, kind of like
having
an oscilloscope calibrated and verified with a sticker.
It would be nice to see what your own individual K2 performance numbers
are
against an expensive spectrum analyzer that most of us don't have.
I, for one, would be willing to pay for that service, within reason of
course.
Hopefully there are others that would too that would make this a service
Elecraft could offer?
Any input would be appreciated.
Thanks!
