The power plant at WP3XEN. Since commercial power was unavailable at the site, WP3XEN generated its own power. The large gray object on the flatbed trailer is a tank of diesel oil. The large generator (center) provided three-phase power for running the transmitter and everything else on the site. To save fuel, it was turned off when the station signed off for the evening. The smaller generator (left) provided power for the security lighting and for everything in the construction trailer. Security guards were stationed on the site at all hours when WP3XEN was off the air. The wooden shed to the left of the trailer contained an automatic generator transfer switch.
