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 |
