[Skimmertalk] [RBN-OPS] Getting the RBN (and your node) ready for CQWW

I don't know of any requirement but I have always done that because the qs1r/skimmer generates lots of spurious spots because of overload from the local station transmitting.

Question without notice - 
I have asked the CQWW Committee for clarification but have received nothing back for this weekends contest. 
Does Any one know Is there a requirement for a Skimmer that is attached to the RBN operated by one of the ops of a Multi op to NOT display the multi ops Callsign ? ie filter it out ?

We've been working hard
recently on improving, as much as possible, the fail-safeness (is
that a word?) of the RBN's
central server. While a few single points of failure are
inevitable with our current architecture, we're trying to make
sure that every function will either restart automatically if it stalls, or else
notify several of us that it needs attention.

Now, what can you
do, as an RBN node operator? With CW Skimmer, the only
thing you need to do is to select the CW Contest "band plan" on the
"Misc" settings tab. That should give you plenty of

With Skimmer
Server, you need to look at the .ini file you plan
to use for the contest period. You'll find a line like this
(from the default file):



You'll note
that in the case of Skimmer Server, decoding stops by
default at 90
KHz above the lower band edge. In CQWW CW this may
not be enough, especially on 20-10 meters. Of course,
the bandwidth you cover directly affects how
much CPU is needed, so on a big contest weekend
it's a bit of a balancing act. 

In areas with a lot of RBN nodes, such as
Western Europe and the US East, you might even
want to coordinate with your local colleagues
and divide up the decoding range.
