[Skimmertalk] red pitaya, for real?

[Dai NAGAKURA]

Dear members de JF2IWL

I am now Skimmer beta testing of S9-C SDR by BA4TB, Dale
http://www.rabbit-sdr.com/
(This page is written in Chinese, Translate to Engilish)
or See eHam net
http://www.eham.net/ehamforum/smf/index.php?topic=104347.0

I show comareing analysis of 24h CW SkimerServer Result by SH5 below
This is from local Spots.txt data, 
using  devided exactly same antenna. 192 kHz 4 bands 

QS1R (PC=CoureDuo 2GHz 2MB Memory)
http://59925.org/sh5/jf2iwl/2016/2016_spots_by_qs1r_jf2iwl_s/index.htm
about 3000 capture and 77 coutry

S9-C (PC=Corei7 3.5GHz 16GB Memory)
http://59925.org/sh5/jf2iwl/2016/2016_spots_by_s9-c_jf2iwl_s/
3200 capture ,81 country

I feel S9-C's ability is as same as QS1R's
although PC for S9-C is mutch higher than QS1R is.
It captures IBP beacon very well = (It shows High speed respnse)

Also , S9-C can run RTTY skimerserver
I challenged decode by S9-C in SCC RTTY Contest last week.(22hours)
http://59925.org/sh5/jf2iwl/2016/2016_scc_rtty_championship_jf2iwl_s/

I cannot comment because I have not compared with QS1R
but good result I think

S9-C can be run 192kHz 8 bands
Now I am testing compareing QS1R 7bands  and S9-C 8 bands sagain.
I post result after Russian RTTY contest.compareing 
RTTY skimmer ability.

Now I have another Core i7 PC.
