[Elecraft] K2 #5549 some questions/remarks

[Jurgen ON5MF]

Hi everyone,

thanks for the replies so far.

No the spurious we see are not due to overloading of the spectrum 
analyser. They are really there! We saw them on 30, 12 and 10m, the 
other bands were a lot 'cleaner'.

We (ON7KZ and I) have no time to get into it in the first few days but 
the file http://www.qslnet.de/member/la3za/K2/BpfDL7MAJ.pdf seems pretty 
helpful.

More info to follow here or on my homepage.

Any hints or tips are still welcome!
