Most-Logged Stations in CQ WW CW and SSB Contests, 2017

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 2017, the ten stations with the largest number of appearances in CQ WW SSB logs were:

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

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 2016:

Callsign	Appearances	% logs
CN3A	8,696	57
CN2R	8,333	55
9A1A	8,111	53
LZ9W	8,072	52
PJ2T	7,729	45
EF8R	7,677	53
YT8A	7,629	50
CN2AA	7,268	51
PJ4X	7,087	44
DF0HQ	6,752	47

Similarly, the ten stations with the largest number of appearances in CQ WW CW 2017 were:

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

And the equivalent table for 2016:

Callsign	Appearances	% logs
HK1NA	10,277	59
9A1A	9,921	63
TK0C	9,682	61
CN2R	9,675	63
PJ2T	9,569	53
CR3W	9,354	60
LZ9W	9,091	59
CN2AA	8,912	59
P33W	8,661	56
EF8R	8,409	57

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 2008 to 2017, we find:

Callsign	Appearances	% logs
LZ9W	82,463	57
CN3A	79,752	59
DF0HQ	77,755	56
OT5A	71,370	53
PJ2T	69,695	47
K3LR	69,026	51
P33W	65,432	50
A73A	60,563	46
CN2R	60,356	48
DR1A	56,425	40

 And for CW over the same span:

Callsign	Appearances	% logs
LZ9W	92,842	66
9A1A	88,714	62
PJ2T	87,728	57
DF0HQ	82,412	62
P33W	72,498	54
W3LPL	71,859	52
K3LR	71,438	52
LX7I	69,457	53
PJ4A	68,654	52
D4C	65,049	43
