Call Busts and Reverse Busts in CQ WW, 2005

The availability of augmented versions of the CQ WW public logs makes many interesting analyses rather simple.

One obvious example is a listing of the stations with the largest number and percentage of busted calls and reverse busts (i.e., calls that were busted by others).

Below are the results for the first year for which public logs are available, 2005.

2005 SSB -- Most Busts
Position	Call	QSOs	Busts	% Busts
1	CT3YA	13,104	303	2.3
2	YV4A	8,304	110	1.3
3	OT5A	9,710	103	1.1
4	EA8ZS	4,005	102	2.5

2005 SSB -- Most Reverse Busts
Position	Call	QSOs	Reverse Busts	% Reverse Busts
1	OH5BM	4,158	1,904	45.8
2	DF0CG	10,232	132	1.3
3	DQ0Q	10,060	131	1.3
4	IS0/DL3EW	5,773	130	2.3
5	CT3YA	13,104	122	0.9
6	HB0/HB9AON	6,005	108	1.8
7	TM2Y	4,874	104	2.1
8	4X1DX	3,955	102	2.6
9	NN3W	2,355	101	4.3
10	S580A	1,087	94	8.6

In tables of reverse busts, one sometimes finds what seems like an unreasonable number of reverse busts (as, in this table, for OH5BM). 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.
