CQ WW DX Contest CW 2014 Raw Scores

The Raw Scores for the CQ WW DX Contest CW 2014 are now available at http://www.cqww.com/raw.htm?mode=cw

The raw scores are for logs received as of 2100 UTC on December 7, 2014. We had 7,250 logs received at that time.  Additional updates will be made each week as more logs are received. Checklogs are not listed in the raw scores.

The raw scores are calculated by the CQWW log checking software before log checking with duplicate contacts removed. The score generated by your logging program and ours may have slight differences due to country files and some contacts not being accepted. If you see a large difference, please report this to questions@cww.com.

If you do not see your log in the raw scores, first confirm that the log has been received by visiting http://www.cqww.com/logs_received_cw.htm

Thanks to everyone who participated or submitted a log for the contest. We enjoyed some of the best conditions ever in the history of the CQWW CW Contest!

CQ WW CW 2013 Log Checking Reports

An email with a link to the Log Checking Report has been sent to everyone who submitted a log for the CQ WW DX Contest CW 2013. The Log Checking Report includes a complete summary of how the final score was calculated and any errors or deductions that may have occurred. We make these reports available so participants can have the opportunity to learn from their mistakes.

How does your accuracy compare to others? The chart below shows the number of errors by percentage and the cumulative percentage of entrants in that bin.

 

WW CW 2013 Error Rates Chart

 

Table. Numeric values for chart

Error Rate bin Number of logs Cumulative %
<0.100% 386 5.19%
0.500% 113 6.71%
1.000% 565 14.30%
2.000% 1658 36.58%
3.000% 1347 54.68%

30.000% 68 99.76%
40.000% 17 99.99%
More 1 100.00%

For example, there were 1658 logs with an error rate between 1.0 and 2.0%. 36.5% of the total entrants had an error rate of 2.0% or less. The median error rate was 2.7%. This is an amazingly good result when you consider the total number of contacts made during the contest.

How fast do people send in WW CW?

Bob Wilson N6TV did some analysis using new columns in the raw data archived by the Reverse Beacon Network.

We finally have an answer to that age old question, “So, how fast do people send Morse code in CQ WW CW?”

Answer:  about 30 WPM

Shown below is the average CW speed of all the RBN spots, by continent (of the DX).
Those African DXpeditioners really know how to QRQ (especially EF8U).  And yes, most slow down a bit on Sunday, even if conditions improve:

Do people send slower on the low bands?  Yes, the lower the band, the slower they go.

Map showing typical RBN data

The RBN collects data from receivers around the world and stores it into a database. These reports include call, frequency, signal-to-noise ratio, and CW speed. More information about the Reverse Beacon Network is available at http://www.reversebeacon.net/

Thanks to N6TV for sharing his analysis.

CQ WW 2012 Changes to Disciplinary Actions

The official results for the CQ WW DX Contest 2012 have appeared in CQ Magazine. Several questions were received regarding disciplinary actions taken by the CQ WW Contest Committee. After thorough discussion within the Committee the following changes were adopted:

The entry for OL3Z (ops OK1FCJ, OK1FPS, OK1HMP, LZ1RGM) is changed from Red Card to Yellow Card.

The rules for warnings and disqualifications are being updated for 2013. The 2013 rules will implement a new approach to the actions of the CQ WW Contest Committee for warnings, disqualifications, and appeals.

Corrections will appear in the errata of the results and in the online score database.
