Stations With Lowest Probability of Busting a Call in Non-Run QSOs: CQ WW 2005 to 2016

Prior posts in this series:
In this post I list the calling stations (i.e., not the running station) with the lowest probabilities of busting a call in CQ WW from 2005 to 2016, using the procedure developed in the second post above.

We can easily compare the annual weighted mean values of $p_{bust}$ for SSB and CW:


I note that the Reverse Beacon Network (RBN) came online in 2009, and although its G(15, 100) scatter metric shows little change between November, 2009 and November, 2010, it seems likely that far fewer operators were aware of its existence and utility in 2009 than in 2010. It is reasonable to suppose (although I have made no attempt to test the hypothesis) that the existence of the RBN is at least partly responsible for the consistent improvement in accuracy on CW that started in 2010.

If you wish to perform your own analyses, a file of the weighted means of the $p_{bust}$ probability function for each individual station (not just the top-ten stations listed above) is available for the period 2005 to 2016. (You can, of course, create your own dataset(s) from the full augmented data files.)
