Most-Logged Stations in CQ WW CW and SSB Contests: 2024, and the decade from 2015 to 2024

The public CQ WW CW and SSB logs allow us easily to tabulate the stations that appear in the largest number of entrants' logs. For 2024, the ten stations with the largest number of appearances in CQ WW SSB logs were:

Callsign	Appearances	% logs
CN3A	15,857	72
D4C	12,973	63
LZ9W	12,391	60
M6T	12,335	61
P33W	12,206	62
CR3A	12,079	63
9A1A	11,911	59
YT5A	11,585	57
DF0HQ	11,439	58
V26B	11,327	56

The first column in the table is the callsign. The second column is the total number of times that the call appears in logs. That is, for example, if a station worked DF0HQ on six bands, that will increment the value in the second column of the DF0HQ row by six. The third column is the percentage of logs that contain the callsign at least once.

Similarly, the ten stations with the largest number of appearances in CQ WW CW 2024 were:

Callsign	Appearances	% logs
CN3A	15,208	76
CR3A	13,192	73
M6T	13,079	69
CR3W	12,842	70
9A1A	12,546	69
PJ4K	12,238	66
LN8W	11,414	64
YT5A	11,193	63
PJ2T	11,118	60
K1LZ	10,872	58

I find it interesting to see which stations have had the most long-term activity on the contests. For the ten years from 2015 to 2024 on SSB we find:

Callsign	Appearances	% logs
LZ9W	96,329	55
CN3A	93,558	51
DF0HQ	85,830	53
YT5A	82,583	50
M6T	81,170	50
PJ2T	74,644	41
P33W	70,548	44
K3LR	68,256	45
V26B	65,879	39
CR6K	62,368	40

And for the same years on CW: 

Callsign	Appearances	% logs
LZ9W	105,845	66
CR3W	103,850	60
YT5A	99,323	64
PJ2T	93,857	52
9A1A	88,887	54
M6T	86,850	54
TK0C	83,045	49
DF0HQ	78,680	53
RM9A	74,095	48
LN8W	71,662	47
