An Earthman on Venus (Originally titled "The Radio Man")

An Earth radio experimenter is accidentally transported to Venus and finds himself naked and stranded on a hostile world where predatory plants, enormous spiders, and dictatorial ant-men threaten every moment. He learns that humans are enslaved under giant ant rulers, befriends a local named Doggo, and becomes entangled with a diminutive winged princess whose plight prompts him to organize resistance. The narrative follows his adaptation to alien environments, inventive use of technology, confrontations with rival humans and insect overlords, and a campaign to free or protect the Venusian people while navigating intrigue, kidnappings, and rescue missions.
