Is WSUI the oldest educational broadcast station west of the Mississippi?

QST, January, 1917, page 46 (PDF):
"RADIO LESSONS BY WIRELESS"—A broadcast schedule for "a short radio lesson" and "University news" is publicized by 9YA, the experimental call sign for what was later to become WSUI. "Although it is not mentioned in this article, these broadcasts were most likely sent in Morse code. 9YA was licensed to the State University of Iowa — the 'Y' in the callsign signified that it was operating under a Technical and Training School license."
—earlyradiohistory.us/1917_9YA.htm

"WSUI Iowa City, Iowa—Granted an experimental license in 1919, the station operated with call letters 9YA until June 26, 1922. At that time call letters WHAA were assigned to the station along with 834 kc and 200 watts. Later in the year power was increased to 500 watts, and in 1925 call letters WSUI were adopted. In 1935, the FCC granted the station 1 kw, and power was increased to 5 kw in 1940. The State of Iowa is licensee. WSUI is on 910 kc."
