Most-Logged Stations in CQ WW CW and SSB Contests: 2021, and the decade from 2012 to 2021

 

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 2021, the ten stations with the largest number of appearances in CQ WW SSB logs were:

Callsign	Appearances	% logs
LZ9W	10,680	55
EW5A	10,233	55
YT5A	10,164	54
M6T	10,031	54
PJ2T	9,768	46
ES9C	9,672	54
DF0HQ	9,361	52
A73A	9,329	50
EI7M	9,050	49
CR6K	9,016	49

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 LZ9W on six bands, that will increment the value in the second column of the LZ9W 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 2021 were:

Callsign	Appearances	% logs
TK0C	14,707	73
CR3W	12,889	69
CR3DX	11,513	66
LZ9W	11,363	67
M6T	11,055	65
RW0A	11,009	61
PJ2T	10,953	57
PJ4K	10,639	61
YT5A	10,433	64
ES9C	10,303	62

Note the substantial difference between the SSB and CW tables.

I find it interesting to see which stations have had the most long-term activity on the contests. For the ten years from 2012 to 2021 on SSB we find:

Callsign	Appearances	% logs
LZ9W	91,773	55
DF0HQ	82,643	53
CN3A	75,722	47
PJ2T	69,813	41
K3LR	67,138	45
A73A	64,454	43
P33W	63,731	43
OT5A	63,701	42
HG7T	60,538	43
TM6M	58,986	42

And for the same years on CW:

Callsign	Appearances	% logs
LZ9W	104,503	66
PJ2T	89,627	51
9A1A	86,922	54
P33W	80,440	52
DF0HQ	78,211	53
W3LPL	71,848	47
ES9C	71,104	46
LZ5R	70,921	53
K3LR	70,279	47
YT5A	69,422	49
