Most-Logged Stations in CQ WW CW and SSB Contests, 2018

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 2018, the ten stations with the largest number of appearances in (augmented) CQ WW SSB logs were:

Callsign	Appearances	% logs
CN3A	9,585	61
D4C	8,440	55
EF8R	8,369	56
ES9C	7,649	50
LZ9W	7,643	48
M6T	7,249	49
FY5KE	7,158	46
PZ5K	7,089	46
PJ4G	6,898	43
DF0HQ	6,746	46

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, if a station worked CN3A on six bands, that will increment the value in the second column of the CN3A row by six. The third column is the percentage of logs that contain the callsign at least once.

For comparison, here is the equivalent table for 2017:

Callsign	Appearances	% logs
CN3A	10,347	62
EF8R	9,099	56
CN2R	8,649	55
LZ9W	8,251	53
CN2AA	8,090	54
ES9C	7,941	53
M6T	7,856	52
A73A	7,501	47
PZ5K	7,481	45
DF0HQ	7,372	50

Similarly, the ten stations with the largest number of appearances in CQ WW CW 2018 were:

Callsign	Appearances	% logs
EF8R	12,063	72
CN3A	11,603	70
P33W	10,804	67
CR3DX	10,546	67
9A1A	10,518	69
TK0C	10,318	65
LZ9W	10,026	67
M6T	9,785	65
ES9C	9,521	62
PJ2T	9,455	57

And the equivalent table for 2017:

Callsign	Appearances	% logs
TK0C	10,719	63
9A1A	10,594	65
M6T	9,884	62
CR3W	9,783	61
YT5A	9,692	63
PJ2T	9,661	53
EF8R	9,538	60
LZ9W	9,257	60
V47T	9,128	55
CN2AA	9,092	58

We can also perform the same analysis for, say, a ten-year span, to show which stations have most consistently appeared in other stations' logs. So, for CQ WW SSB for the period 2009 to 2018, we find:

Callsign	Appearances	% logs
LZ9W	84,898	56
CN3A	84,806	59
DF0HQ	78,670	54
PJ2T	71,826	47
OT5A	71,036	51
K3LR	69,954	49
P33W	66,944	49
A73A	63,280	46
CN2R	59,700	45
V26B	57,338	41

And for CW over the same span:

Callsign	Appearances	% logs
9A1A	99,223	67
LZ9W	96,166	66
PJ2T	91,295	57
DF0HQ	84,414	61
P33W	83,190	59
W3LPL	74,354	52
K3LR	73,820	52
PJ4A	69,920	51
LX7I	66,448	50
CR3L	64,432	44
