In 1941, Hammer Field (which later became Fresno Air Terminal) was constructed, as a training base for the Army Air Corps. The KMJ tower was directly in line with the runway, and the Army wanted the site relocated. The transmitter was then moved some 16 miles west of Fresno, to the intersection of Madera and North Avenues in Kerman. The transmitter building was moved to the Kerman site, and the existing tower was unstacked and moved as well; however, it was only 660 feet in height. The remaining 330 feet were stored on the site, with the intention of creating a directional array, although World War II interrupted the project and it never resumed. The extra portion was eventually moved to Sacramento, and used in the construction of the KFBK transmitter site in 1945.
