My K2 has 0.1uV sensitivity for 10 dB signal to noise on 10m with
pre-amp on, or 0.16uV with pre-amp off. The K2 has quite low gain
compared to many radios and often needs the pre-amp switched in for the
higher bands, also have you checked the alignment?
There are various tables of measurements on my web site at:

K2 #1892, K3 #80
------------------------------------
I have not been able to find any posts about the sensitivity on
15m-12m-10m being
not so great. On 40m-80m-160m it is what I would expect. 20m it's just OK
with wider filters, but there is plenty of internal noise with the
narrower filters.
