[Elecraft] K2 Performance question

[Don Wilhelm]

Jacob,

Short of testing, there is not much I can say to answer your questions.  
You can just trust, or you can obtain instruments to measure.

I would suggest that you obtain a low level signal generator such as the 
Elecraft XG3 or XG2 to make MDS measurements (using the techniques and 
calculations shown in the manual) to determine if your K2 sensitivity is 
"up to par".

The other answer is "to trust" -- the K2, when the bandpass filters are 
properly aligned and L34 is adjusted for the best S/N ratio will be a 
"hot" receiver.  So if your construction practices  were "by the book" 
and your alignment procedures were all within tolerance - then you will 
have a K2 that performs quite well, and likely exceeds specifications.

73,
