[SCCC] Skimmer Networks

[Dave Hachadorian]

I use VE7CC's CC-User program to connect to a telnet node that 
carries CW/RCK skimmer spots, usually VE7CC-1.  CC-User has 
extensive filtering commands for telnet nodes, especially 
CC-Cluster nodes,  and feeds spots to N1MM Logger.  For CW, I 
usually set spotterstate=UT, NV, CA.  For RTTY, I use all USA 
spotters, because the best RCK Skimmers are on the east coast. 
For SSB human spots, I usually pick W6, W7, W0, W5.  I use 10 
minute timeout for CW, 15 minutes for RTTY, and 20 minutes for 
ssb.  CC-Cluster nodes can eliminate dupes, and do quality 
checking.

All SCCC'ers,

I have been running DXSpider on a Raspberry Pi as a dedicated 
node to
feed N1MM worldwide spots and either the RBN or RCK skimmer 
network for
the particular contest I am playing in.  I have the N6WS-2 
DXSpider node
set to filter out dupes within +/-200 Hz, and not update the same
callsign within that frequency range for 10 minutes.

I was wondering how many SCCC members use RBN, RCK, or local 
skimmers to
populate bandmaps.  If you do use the skimmer networks, what 
method do
you use to filter out duplicates or to add source filters. 
During
contests I typically set my source filters in the morning hours 
for
zones 1-5, & 14, and in the afternoon shift to zones 1-5 & 25. 
I'm not
sure that is optimum, but it works pretty good for me.  I set 
N1MM to
timeout spots after 10 minutes which keeps the bandmap pretty 
current.

My N6WS-2 DXSpider node is used occasionally during contests by 
some of
the other local contesters, but I am usually the only user. 
N6WS-2 is
accessible at n6ws.dyndns.org:7302, if anyone wants to see how it
works.  If you would like to limit the spots to zones 1-5, you 
can use
the command:

reject/spot 1 not by_zone 1,2,3,4,5

If anyone has any thoughts on improving this this method of 
populating a
bandmap, I would appreciate any suggestions.

TU es 73,
Bill
N6WS
