Overlay Category Results and Certificates

A number of people have asked where to view the results of the Overlay categories. Because the Classic Overlay can have a different score than the traditional entry, we have moved all Overlay category results to a separate database.

You can view the results for the Rookie Overlay and Classic Overlay at http://www.cqww.com/overlayscores.htm

This page allows you to select the year, mode, overlay category, and other filters. The certificate links will produce the appropriate certificate for the Overlay category score/result.

There were two new Overlay categories introduced in CQ WW for 2013.  The Rookie Overlay is limited to entrants that have been licensed for less than 3 years at the time of the contest. The Classic Overlay is for single operators, using only one radio, no assistance, and limited to 24 hours of operating time. Both of these Overlay categories will be continued in 2014.

CQ WW 2013 Results now Online

The results of both modes of the 2013 CQ WW DX Contest have been posted to the CQ Magazine web site.

The online score database cqww.com has been loaded with the 2013 scores. There are many ways you can enjoy the scores here on the site:

View the online database. http://www.cqww.com/score_db.htm

Entering a call will show you all CQ WW entries where that callsign was used for the station or listed as an operator.  We have made an enhancement so that you can now search for multiple calls in one request.  Simply separate the callsigns you want to search for with a comma.  Example, If I want to search for K5ZD, WB5QDW, and WA4ZHU then I would enter “K5ZD, WB5QDW, WA4ZHU”  The results listing will show the callsign matches in bold.  This feature should be useful for anyone who has changed callsigns over the years.

Find your results and download an electronic certificate in Adobe pdf format. Certificates are only available for 2012 and later AND for entries that were received by the log submission deadline.

There were two new Overlay categories added to CQWW in 2013: CLASSIC and ROOKIE. Since these are competitions that run in parallel to the traditional categories, we decided to present the results separately as well. Visit http://www.cqww.com/overlayscores.htm to see the Overlay scores.  This one page does it all.  You will need to select Contest Mode (SSB/CW), Overlay (CLASSIC/ROOKIE), Power Level (ALL, HIGH, LOW), and Year (2013). The Cert links on the Overlay results are for the Overlay category certificates.  If you entered an Overlay category, you have the opportunity to get a traditional category certificate and another one for the Overlay category.

The Records page has the all time records for the years included in the database (currently 1977-2013). Always fun to see who holds the records at the World, Continent, and Country levels. USA, Canada, Japan, and Russia also show records by call area.  You can also view all time records by CQ Zone.

There is also a page that lets you see the historical winners for a category/geography over the years.  Always fun to see how scores have changed over time.

Want to see how good the best operators are?  You can view Log Checking Reports of the World high scorers at http://cqww.com/lcr/  You can also view all submitted logs at http://cqww.com/publiclogs/  Might be able to learn a few strategy tips in there.  Especially if you have a copy of your own LCR and try to figure out how a logging error might have been caused.

For those participating in the club competition, there is an Excel spreadsheet that shows the entries and points that were used to calculate the final results. You can find the link to the file from the Results page under 2013 CW.

You can see how activity is growing in CQWW over the years both at the world level and for your country. Visti the statistics page. http://www.cqww.com/stats.htm

The score database will continue to grow as N2NC and his team continue typing in the old results.  As of today, including the years 1977 to 2013, there are 144,409 entries in the SSB database.  There are 135,246 entries in the CW database. We look forward to increasing that number when the 2014 edition of the CQ WW Contest arrives in October and November!

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%
4.000% 921 67.05%
5.000% 584 74.90%
10.000% 1305 92.43%
20.000% 477 98.84%
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.

A few more statistics from the contest log checking.

 7,442 logs total
5,505,384 QSO total
 205 different countries
 39,950 ( 0.7%) QSO with unique calls
 22,495 (56.3%) unique calls busted 
 55,672 ( 1.0%) dupes
 323 ( 0.0%) Cabrillo format errors
4,871,227 (88.5%) QSO checked against another log
4,729,508 (97.1%) QSO checked good against another log
 73,087 ( 1.5%) busted calls
 22,165 ( 0.5%) busted exchange
 46,467 ( 1.0%) not in log

The scores in the LCR are what will appear in the official results. The results for CQ WW SSB and CW 2013 are scheduled to appear in the May 2014 issue of CQ Magazine.

CQ WW SSB 2013 Log Checking Reports

Everyone who submitted a log for the CQ WW DX Contest SSB 2013 has been mailed an encrypted link to view their Log Checking Report for the contest. The reports were sent to the email address that submitted the log and to any email address included within the log (using the EMAIL tag).  If you have not received your report, please check your spam filters. You can request the link at: https://cqww.com/contact.

You can view a sample Log Checking Report here: k5zd.rpt

Some statistics from the log checking process:

8,482 logs total
5,551,137 qso total
 228 different countries
 58,328 ( 1.1%) qso with unique calls
 29,914 (51.3%) unique calls busted 
 45,380 ( 0.8%) dupes
 443 ( 0.0%) Cabrillo format errors
4,547,210 (81.9%) qso checked against another log
4,416,925 (97.1%) qso checked good against another log
 73,173 ( 1.6%) busted calls
 19,108 ( 0.4%) busted exchange
 38,004 ( 0.8%) not in log

It is rather remarkable that almost 82% of the 5 million contacts reported were able to be cross checked with other logs. Thanks to everyone who submitted a log and helped make this level of cross checking possible. Even more amazing is that 97.1% of those contacts cross checked as being good.

The log checking report provides full details on how the final score for each entry was calculated.  It shows the raw score before checking and the reductions. Each Not-In-Log, busted callsign, and busted exchange are listed.

Unique QSOs are also listed for information purposes.  A unique QSO is one with a callsign that was not reported by any other station.  Over half (51.3%) of these were found to be busted calls.  But, experience says these unique QSOs are probably bad calls more than 90% of the time.

We have introduced a new Error Rate calculation to the reports this year. This number represents the percentage of contacts that were found to be in error. It does not include duplicate QSOs. This number is a more accurate representation of accuracy than looking at the percent score reduction, which can be much higher for smaller logs where the penalties and lost multipliers can have a higher impact than they do for large logs.

You can see the Error Rate number as part of the score summary section.

    1.3% Score reduction
    0.3% Error Rate based on claimed and final qso counts
       5 (0.2%) calls copied incorrectly
       0 (0.0%) exchanges copied incorrectly
       0 (0.0%) band change violations
       6 (0.2%) not in log
      15 (0.5%) duplicates (Removed without penalty)
       1 (0.0%) calls unique to this log only (not removed)

The average Error Rate for all logs was 3.60%. Use the chart below to see how your error rate compares to others. The blue lines show the number of logs with that error rate. The red line shows the cumulative number of logs at that error rate or lower. Someone with a 9% error rate was in the top 73% of all entries.
