SegmentSel192 indicates which of the listed segments (CenterFreqs) are selected (enabled). You can only enable a max of 8 segments on each Red Pitaya receiver (RP-16 provides two independent 8-segment receivers).

This assumes 192 kHz Skimming:

Rate=2

Here's the actual code from my RP's second receiver's SkimSrv2.INI file, dedicated to the "unusual" bands including 10m beacons:

CenterFreqs192=226700,563000,1891000,3591000,5421500,7091000,10191000,14091000,18159000,21091000,24981000,28091000,28273000,50091000,50273000
SegmentSel192=011010000010111
CwSegments=135700-137800,472000-479000,1800000-2000000,3500000-3600000,5330000-5407000,7000000-7125000,10100000-10130000,14000000-14150000,18068000-18115000,21000000-21200000,24890000-24935000,28000000-28300000,50000000-50200000
Rate=2

The number of 1s and 0s must match the number of values in the CenterFreqs section (length of lists should be the same).

Once set, you can reset the values using the SkimSrv checkboxes which correspond to the 1s and zeros:

Is this something that needs to be adjusted ?

Ooops I meant to send this to group.  I see now that you're asking about
all beacons, not just the NCDXF Beacons.

To monitor beacon frequencies on 10m, you have to dedicate a 192 kHz
receiver slice to 10m CW  28182~28300 and update SkimSrv.ini or
SkimSrv2.ini to look like this:

CenterFreqs192=136750,475000,1885000,3585000,5417000,7085000,10185000,1408
5000,18153000,21085000,24975000,28085000,28255000,50085000,50255000
SegmentSel192=111010000010110
CwSegments=135700-137800,472000-479000,1800000-2000000,3500000-3600000,533
0000-5407000,7000000-7125000,10100000-10130000,14000000-14150000,18068000-
18115000,21000000-21200000,24890000-24935000,28000000-28300000,50000000-50
