The P4 Aruba Callbook, last updated in 2010, serves as a directory for amateur radio operators active from the Caribbean island of Aruba.

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).

The original SurplusEQ.com domain, once a hub for amateur radio operators and electronics enthusiasts seeking test equipment, meters, and various high-tech components, has been repurposed. Historically, such platforms facilitated the acquisition of essential gear for shack setups, antenna analysis, and general electronics work, often providing cost-effective alternatives to new retail purchases. The site's previous focus on "test equipment, meters, testers" directly supported the technical aspects of the hobby, from RF measurements to circuit diagnostics. Currently, the domain points to a gambling platform named "SEMUTWIN," offering online slot games, live casino options, and other digital wagering activities. This shift represents a complete departure from its former identity as a resource for surplus electronics and amateur radio-related equipment. The content now features game titles like "Sweet Bonanza Super Scatter" and "Gates of Olympus Super Scatter," alongside promotional offers for online gaming.
