The P4 Aruba Callbook, last updated in 2010, serves as a directory for amateur radio operators active from the Caribbean island of Aruba. It meticulously categorizes P4 callsigns into several types: **P41-** for special resident calls valid for one month, **P43-** for permanent resident calls renewable annually, **P49-** for permanent visitor calls also renewable annually, and **P40-** for temporary visitor calls valid for one month, often used in contests. The resource notes that obtaining a permanent visitor callsign requires passing a local examination. The callbook lists numerous specific callsigns, including their QSL routes, operator names, and sometimes addresses or activation dates. For instance, P41A routes via P43A, and P40HQ was used by P43ARC via I2MQP for IARU contests. The entries include both active and Silent Key (SK) operators, with dates of passing where known, such as P43ADA (SK, Sep 2014) and P43JB (SK Jan 2012). This detailed listing assists DXers and contesters in verifying contacts and ensuring proper QSLing for Aruba operations.
