Call Busts and Reverse Busts: CQ WW 2017

This is the thirteenth in a series of posts on busts and reverse busts in the CQ WW contests. These posts are based on the various public CQ WW logs (cq-ww-2005--2017-augmented.xz; see here for details of the augmented format).

Prior posts in the series on busts and reverse busts in CQ WW:
In this post, we include only verified QSOs; that is, QSOs for which both parties submitted a log. This is a change from earlier years' posts.

First, the tables for the 2017 SSB data:

2017 SSB -- Most Busts

10 PD5ISW 136 11.0

2017 SSB -- Highest Percentage of Reverse Busts (≥100 QSOs)
Position Call QSOs % Reverse Busts
1 VR20C 112 69.6
2 VR20FUN 134 25.4

8 BI4IV 40513.6
9 BG8SXC 130 10.8
10 LU9DDJ 701 10.4

In tables of reverse busts, one sometimes finds what seems like an unreasonable number of reverse busts (as, in this table, for VR20C). This is generally caused by a discrepancy between the call actually sent by the listed station and the one recorded as being sent in at least some QSOs in the log, although it can, of course, be due to an unusual callsign structure (as appears to be the cause in the instant case) or poor audio quality.

Now the tables for the 2017 CW data:

2017 CW -- Most Busts
