I am following your experiments with interest.

So you need to make a several changes in the "ini" file to add frequencies.

1)  Yes, you need to add the center frequencies.  Here is an example of the
line from one of my machines operating with a 48 khz bandwidth

CenterFreqs48=130000,470000,1822000,1866000,3522750,3568250,5354000,5399000,
7022750,10120750,10163000,14022750,14068250,18090750,
21022750,21068250,24912750,28022750,28068250,50022750,
50068250,50113750,50159250

2)  Then you have to add the segment to the following line:

CwSegments=135700-137800,472000-479000,1800000-2000000,
3500000-3600000,5330000-5407000,7000000-7125000,10100000-10150000,14000000-
14150000,18068000-18110000,21000000-21200000,24890000-
24930000,28000000-28300000,50000000-50135000

3)  Then you have to decide which of the segments to turn on.  I am running
this on the Red Pitaya so I can have 8 of these segments on at one time
although on this machine I only have 6 turned on at the moment.

SegmentSel48=11000011011000000000000

Email me directly if this is not clear.
