- Feb 18 4:23 PMHi Rick,
CW Skimmer produces 24 kHz of spectrum in the SoftRock-IF mode but displays
only as much as your screen allows. You need a higher resolution monitor to
see more spectrum on the waterfall. Note that it still decodes all 24 kHz,
even the parts that you cannot see.

Since we're on the issue of bandwidth I have a question. Using
CWSkimmer 1.4 I get a bandwidth of +/- 9 Khz. Or a total bandwidth of
18 kHz. What has happened to the other 6 kHz?
Don't get me wrong, 18 kHz is really good but I was wondering if I
have something set incorrectly or is this normal?
I'm using a Ten-Tec Orion, LP-PAN, 192 kHz E-Mu 0202 sound card and
