Jurgen:

I've made some simple receiver sensitivity measurements and posted my 
results, along with those made by W5EWA, at 
http://www.cliftonlaboratories.com/k2_rx_sensitivity.htm. I also plan to 
make some spurious output measurements today and will post those as 
well. I've done earlier measurements on my K2 with an HP8558B spectrum 
analyzer, but now have a much better Advantek R3463 spectrum analyzer 
with an easier way of getting data into the PC.

Do you have specific test frequencies that are of concern to you?
