[Skimmertalk] Decoding slow beacons on 10M ?

[Bob Wilson, N6TV]

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:
