[Skimmertalk] new rp vs cwsl_tee

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.

CenterFreqs48=475000,1821250,1863750,3521250,3563750,5353250,5395750,7021250,7063750,10121750,14021250,14063750,18089250,21021250,21063750,24911250,28021250,28063750,50021250,50063750,50106250,50148750,50191250
CenterFreqs96=475000,1842500,3542500,5374500,7042500,10142500,14042500,18110500,21042500,24932500,28042500,28127500,28212500,50042500,50127500,50212500

RttySegments=1800000-1820000,3520000-3573900,3577000-3600000,5330000-5407000,7020000-7073900,7077000-7100000,10130000-10132000,10139000-10150000,14060000-14073900,14077000-14150000,18109000-18115000,21060000-21073900,21077000-21150000,24910000-24930000,28060000-28150000,50250000-54000000

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.
