[Skimmertalk] new rp vs cwsl_tee

Great, I’ll put them in shortly.  I did try notching just 20m an hour or so ago because it had upwards of 300 decoders running where other bands were much lower… it decreased the number of decodes down to about 100 on that band which still seems a bit high but not bad at all.

I haven't bothered excluding FT8 frequencies from CW Skimmer since they don't chew up much CPU time, or generate false spots, as far as I can tell.  RTTY is a different story.

I did add all the new bands and moved the center frequencies up so that the beginning of each band is always at the far left edge of the HDSDR display (and the frequencies make more sense when viewed in Skimmer Server).  Here's what I have so far for CW center frequencies for the "main" skimmer of SDR 122.88-16 (traditional bands CW and RTTY).  On the "secondary" skimmer (MAC address FFXX) I select the new bands and no RTTY skimming.

Watch out for line wrap when pasting into .ini files.  Each keyword starts a line, and the rest must be on one long line.

I've excluded some of the FT8 frequencies (not complete) but not the FT4 frequencies.  This will have to evolve.  Using the spectrum display of RttySkimServ is helpful to see if you've "notched" the FT8 frequencies properly.  There is no equivalent in CW Skimmer Server.

Outside of Contest Weekends, my RTTY Skimmer spots very few stations these days.

Ah, that’s better.  now just one more thing, does anyone have a CwSegments list that ignores all the hf ft8 frequencies?  And is there an equivalent one for rtty skimmer server??

BTW, having separate gigabit switches for the rp’s and their computers made all the difference here…  when I was pulling out the old cables I found that the computers were plugged into my dsl router ports which are only 10/100mbps, no wonder it was choking when I tried to put the new one through there also!
