Actually, KFRO moved twice...
They indeed launched on 1370. That was a so-called "local" channel, on which they were limited to 100 watts daytime only. If they'd stayed on 1370 as a local station, in 1941 they would have been shifted to 1400 along with the other local stations on 1370.
But they didn't stay on 1370. Sometime before 1940, they shifted to 1340, a "regional" channel. On 1340 they could increase power to 1,000 watts and add nighttime operation. (I'm assuming directional but it doesn't say)
Then, a year later, the big 1941 shift happened -- and KFRO got shifted back to 1370 where they started. (the seven other stations operating on 1340 also got moved to 1370)
