Cathy,
There was a geomagnetic storm recently which may be affecting things. Wait
a few days and see, or if you have the equipment, you can measure your
receivers sensitivity if need be.

Subject: [Elecraft] K2 insensitive on 20...or is it?
I am seeing some odd behavior on my K2, and it may be just in my
imagination.
On 40, with its normal higher background level of QRN, I can easily get
strong signals and strong noise levels. With the AF and RF gains turned
up, I have comfortable armchair reception. If the S/N ratio is bad that
night I may not get an intelligible signal, but it is clear that things
are working nicely.
But when I attempted to look for QSOs in the recent Run for the Bacon, I
not only found very few CQers on 20, it seemed that both their signals and
the background noise (which of course would be lower on 20 anyway) were
very weak. Even with the preamp on and the AF and RF gains at max, I
don't feel that I have armchair copy even on the *noise*. The S/N seems
pretty normal, but I feel as though I can't turn up the volume to make the
combined S+N very loud on the speaker. (Again, this problem does not
exist on 40.) The noise level on 20 does change as expected when I vary
the filter width. If I switch to USB/RTTY mode with wide filters and tune
in 14.070, the strong PSK signals there just about blow me out of my
chair, so it isn't always insensitive...
I am probably just imagining this. Has CW on 20 been lousy lately? Any
objective way to test it? I am a pretty inexperienced op who has really
only gotten serious about CW in the past 4 months, so I don't have much
experience to draw on.
