Farnsworth worked while his sister Agnes took charge of the family home and the second-floor boarding house, with the help of a cousin living with the family. The Farnsworths later moved into half of a duplex, with family friends the Gardners moving into the other side when it became vacant. He developed a close friendship with Pem's brother Cliff Gardner, who shared his interest in electronics, and the two moved to Salt Lake City to start a radio repair business. The business failed, and Gardner returned to Provo.
