Not had any problem either. The massive pileups this Spring presented
no display problems. This good experience goes back for at least 5
years with several computer systems and a couple sound cards.
Wonder if the birdies/spurious signal problems are due to not doing the
I/Q equalization or some kind of bad solder joint either. If you did
it, do the results look reasonable? (Equalization here is done with a a
signal generator with pure output)
The other possibility is that the sound card is being over driven.
The only problem I've encountered is when the DX comes back to a station
and SKIMMER then spots it on the DX stations frequency. Watch out for that!

the DX on SUB (locked), and see all the callers on Skimmer's interface.
Find
the guy sending 5NN TU and pounce. The only problem was that everything
from
about 4 to 6 kHz above the DX frequency gets obscured by the
birdies/mirror
images on the skimmer display. And since most big DXpeditions split up, I
would lose a ton of callers in that murky no-man's land. The skimmer
turned
out to be no help at all on some of the massive DXpeditions earlier this
spring as a result. The exception was Heard Island, who were split down,
rather than up. That worked like a champ on a few bands where the pileup
was
insane.
I don't know about the K3S but I've been doing this with the K3 for many
years. I even wrote a macro for fast setup which I published 5 years ago:

It sounds to me like there could be a problem with the K3S's I-Q output
causing your birdies. FWIW I never had any birdie issues using my K3,
LP-PAN and Audiophile 2496 soundcard. I still prefer Skimmer's panadapter
because clicking the last "599" decoder dot will QSY your TX to the exact
frequency (within 10 Hz) once the system is calibrated...no need position a
cursor any closer than the decoder dot.
