New column on the scoreboard page: Authorization source.

We have added one new column to the scoreboard page. It has the title “A” and could be “translated” as an Authorization  source.

Since our server is getting involved into the Real Score Cluster more and more we are going to publish the score postings source.

There are the following options:

C –  posting has been processed and authorized by the server

D – posting has been processed by the server by using authorization API either or COSB

S –  posting has been received directly and processed by the Contest Online ScoreBoard server.


New web site version is online

We’ve done significant re-styling of the COSB web site. Thanks to Randy who made a great effort to clean up all the pages!

The major changes are:

  • The scoreboard page keeps now its scrolling position after auto refreshing
  • The scoreboard page has been re-designed  for resizing to a smaller window
  • The site header has been changed.  Contest selector has been moved to the left edge. That has been done to have it in a smaller window
  • Additional windows (Club, competition, Teams Competition and Rates) open in a dedicated windows

Randy, K5ZD is the new COSB team member

We are so glad to have Randy, K5ZD to join our team! He is well known to almost everyone who has the same passion as we all are – contesting. Member of CQ Hall of Fame,  WRTC-2014 director , incoming   WRTC-2018 judge, ex director of CQ WPX and CQ WW DX contest and many others titles!

Beside that he has a good web experience by enhancing CQ WW and CQ WPX web sites. Randy is going to help us with COSB web sites design and development.

New rate graphs ( Contest progress view)

We have activated a new  graphs view: “Contest progress“:

That may be useful to compare personal performance with some other participant.

A rate window is showing “Hourly view by default as it was before:

We just decided to remove background from all the graph to get better contrast balance.

Switching between two graphs are by marked by red rectangle on screenshot images link above.

Please note these features are available for the only registered users!

Real Score Cluster full functional test

The next great step in the The Real Score Cluster implementation just happened. We did the first full functional cluster test during the last ARRL DX CW contest. All the 100% score postings from over 300 contesters were shared between two scoreboard servers and COSB for the first time!  We didn’t notice any significant gaps during that testing.

Thanks for all  the Real Score Cluster guys who did a lot to make this event a big success:

  • Dmitry, R4WW the owner
  • Bruce, WA7BNM the distributor server creator

How that works:

=> All the incoming traffic to the Distribution server (or Score distributor) is forwarding to COSB and CQcontest

=> All the incoming traffic to the COSB is forwarding to the Distribution server and after- to the CQcontest .

=> All the incoming traffic to the CQcontest is forwarding to the Distribution server and after – to the COSB 

We still have a lot of things to be done to finish the Real Score Cluster infrastructure basement.  Unfortunately during this period might be not all postings to be shared or they could be shared partially.

You could be a part of the project! The best you can do to help us would be configuring your logger to send your scores to the Distribution server ( ).

Please read how to set up your logger to be ready for the Real Score cluster the most efficient way.


A new feature added : Operator call

We’ve got some suggestions to reflect if a guest operator renting a contest shack as a SINGLE-OP. So we have implemented this feature. Such a station call and a guest operator combination will replace just a contest call  being used for a contest. We provide a combined call where an operator call fillows after a station call and split by the “@’ sign:

The call marked by red color means: Station contest call VA2WA operated by a guest operator VA2WDQ. That’s a style similar to what 3830 web site uses.

If you wish to use this feature please configure operator call for a contest. The most popular logging programs N1MM+ and WinTest (by using our utility)  support this feature.  We’ve found this data is missing in the DXLog. Probably some other log also missing that. We have already contacted Chris, 9A5K the owber of DXLog.  So it’s in process now.

A couple of tips about how to use Club competition page

Tip 1:  If you wish to monitor your club activity only activate a club filter by clinking on your club name title.  Your club name title is a link to activate the filter.


Tip 2:  Split the Club competition window and minimize it. Usually a contester’s desktop has dozens opened windows. Every inch should be used effectively  as much as possible)) Look how a small Club competition windows could be:
