[Elecraft] 160M low sensitivity problem?

[Dave Benham]

OK -- 3rd attempt...  A test message was successful this morning, so maybe I
can get in again.

I've been playing around re-aligning my K2 after adding the version 2
upgrade tonight [2 nights ago, now].  Using Spectrogram, I noticed something
I've suspected with the 160M module I added quite a while back.  (I haven't
operated any 160 with the K2, yet).   If I have no antenna on the K2, and am
receiving just noise on 80M, and set the peak of the waveform to -40db, then
switch to 160M, the waveform drops at least 5 db on the Spectrogram screen
(preamp on in both cases) -- this drop is quite noticeable to the ear.  Is
this normal?  The effect is much more pronounced with an antenna attached,
but I don't have a 160M antenna available where I'm doing this test so the
resonance of the antenna would be an additional factor.  If someone out
there thinks I might have a problem, what might it be?  When I built it, the
alignment went OK.

Thanks.
