I asked Gary at Elecraft if he finds much variation in performance with
the radios he works on and repairs. I recall he said that if the radios
have been built correctly there is no variation between radios. I have
compared my rig to the PROII and I could not detected any difference in

Don,
Not sure the price for the tests required would be as steep as you
mention. I think it would be an expense that some would be willing to
pay to be assured that the rig they are using is up to speed. Remember
we are not looking for 1 dB or even 3 dB here, we expect to find
elephants.

Dave,
Yes, I agree. Several folks have sent me their K2 just for such a checkout
and calibration and alignment. I have the advantage of being familiar with
the K2 and its normal behavior. BUT with a little bit of ingenuity, each
builder can determine if his K2 is performing up to par without se

Seems to me that a few might be missing the main point here. While
assembling a K2 there are a few hundred parts to be stuffed into holes.
It is not all that difficult to stuff the wrong part into a pair of
holes. Seems that I remember a firm (Sherwood Engineering I believe was

To each his own. Some people don't have the confidence to do the alignment.

Boy, I don't get this one at all. The whole essence of Elecraft,
IMHO, is doing it yourself and getting something really great for the

You will probably find that even with better filter alignment, your spurs
will not be reduced.
I would tend to believe that you have an oscillator in the K2 that is not
behaving properly. You should check both the BFO and VCO for signal purity

As Don, W3FPR has already pointed out, alignment of the K2 is straightforward
and requires no test equipment. By following the instructions in the manual,
as well as the frequency calibration info provided on Don's website, my dial
calibration is now accurate within about 20 Hz, using WWV as a

Several 'builders for hire' will offer that service for you if you would
like it done for a fee.
The "Facts of The Case" are that you can Do It Yourself. Follow the
instructions in the K2 manual for peaking the K2 bandpass filters (in
transmit), and set the IF filters using Spectrogram, an

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.
