[Elecraft] Skimmer and the K3S

[brian]

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!
