[Skimmertalk] qs1r sharing?

Fri Jan 9 10:51:43 EST 2015

Hi Dave,

I'm running an i3 with 4GB RAM.  It's grossly underpowered for a RTTY
contest, but does great for CW 7x192 on CW contest weekends (without
running RTTY).

I'm currently running 7x96 with both CW and RTTY, but I have the RTTY
subbands set from the equivalent of xx.080 to xx.100, but it's cut off at
about x.091 due to the 96 bandwidth and my center freqs to cover all the
way down to xx.000.  This is, IMO, fine for non RTTY contest times.  People
pretty much stick to 080-090 for RTTY during non-contest times, maybe with
rare exceptions.  (The WARC bands are even narrower.)  I'm running at
around 25% CPU.  CW is set to use 1 thread, RTTY all 4 threads.

When I ran with this during Roundup, I was pegged at 100% CPU and RTTY
Skimmer was employing throttling, meaning it wasn't decoding everything.

Durning non-contest time, I also tried 7x192, but was running about 75% CPU
(was decoding more of the RTTY subbands because it wasn't cut off at
xx.091).  Since I use this server for many other tasks (HTPC, RAID Server),
I decided that 7x96 is fine for everything other than RTTY contests, and
can still do 7x192 for CW contests.

I agree with others...for a RTTY contest, nothing less than an i7 (or as
close as possible with an AMD) would be recommended.

FYI, my non-contest RTTY Segments:
RttySegments=1800000-1820000,3580000-3600000,7025000-7050000,7080000-7100000,10130000-10150000,14080000-14100000,18095000-18115000,21080000-21100000,24910000-24930000,28080000-28100000,50250000-54000000
Contest:
RttySegments=1800000-1840000,3550000-3600000,7020000-7125000,10130000-10150000,14060000-14112000,18095000-18115000,21060000-21150000,24910000-24930000,28060000-28150000,50250000-54000000
