In 1935 we know that he became the a sales manager for the Don Lee Network. But that's a substantial gap. Foreman was 38 years old in 1935. If he served through all of WWI he would have been discharged on or around 1918. The First Whites radio log I have access to is 1925. In that year there is no KFWM, nor is there one all the way through 1935. A 1921 list made by the Department of Commerce also does not include the list. These are the early days of radio. Another 1922 list included only 67 stations. There was however a 500 KFWM-AM in Oakland, CA owned by the Oakland Educational Society. It is possible, that this was recorded incorrectly in one history and repeated elsewhere. Even if it was KFWM, that station ceased to exist in 1929, leaving a mysterious 6 year gap.

Foreman Phillips began hosting country barn dances and other western themed events. One early venue for these was the Venice Pier in California. This was in on or about 1941. In 1938 he crossed the street to do his show on KRKD. In a 1943 Billboard publication it was noted that he was opening other venues around LA. and that he now had a 30 minute program on KRKD and KPAS. The latter was purported to be a country music news. He was talking primarily about the shows he booked, and the artists that played his shows. More on KRKD here.
Foreman was cited in one 1944 article in Billboard for the success he had seen. At the time he was said to have several popular programs airing over KRKD. One of which was still titled the "Western Hit Parade." Phillips was booking move venues and with even bigger artists: Bob Wills, Al Dexter, Patsy Montana, Spade Cookley, the Sons of the Pioneers and hundreds of others.
By 1947, Phillips was said to have 20 hours of air time for his radio programs which were now carried on KRKD, KXLA and KFOX. He quit KRKD in 1947. Cliffie Stone took over as hos of his long-running radio program "Cowboy Hit Parade." In 1951 be began a three-hour show over KECA-TV in Los Angeles. But it wasn't enough to keep him in the biz. He retired in 1952 and died in 1968. The KRKD tower still stands over Los Angeles but hasn't been used in decades.
