Most-Logged Stations in CQ WW CW and SSB Contests: 2025, and the decade from 2016 to 2025

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 2025, the ten stations with the largest number of appearances in CQ WW SSB logs were:

Callsign	Appearances	% logs
CN3A	15,582	68
ES9C	15,242	67
UA7K	12,765	58
CR3A	12,508	62
P33W	12,248	58
M6T	12,194	58
LZ9W	11,953	56
V26B	11,752	55
II9P	11,353	57
RU1A	11,261	57

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 V26B on six bands, that will increment the value in the second column of the V26B 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 2025 were:

Callsign	Appearances	% logs
TK0C	15,843	74
CN3A	15,363	75
CR3A	13,457	70
CR3W	13,147	67
ES9C	13,013	67
PJ4K	12,694	66
ZF5T	12,400	61
M6T	11,982	65
9A1A	11,639	66
PJ2T	11,508	57

I find it interesting to see which stations have had the most long-term activity on the contests. For the ten years from 2016 to 2025 on SSB we find:

Callsign	Appearances	% logs
CN3A	99,447	52
LZ9W	99,238	55
M6T	88,198	52
DF0HQ	87,426	52
YT5A	78,696	47
PJ2T	76,333	41
P33W	75,148	45
K3LR	70,681	45
V26B	70,490	40
CR6K	68,342	42

And for the same years on CW: 

Callsign	Appearances	% logs
CR3W	116,962	66
LZ9W	106,651	65
M6T	96,631	57
PJ2T	95,867	52
YT5A	92,472	59
TK0C	91,591	52
9A1A	89,480	53
CN3A	82,187	43
LN8W	81,036	52
DF0HQ	78,816	52
