W9XUP was a high-fidelity "ultra-high frequency" AM station, and not an FM station

I have removed the statement that KSTP's late 1930s experimental station, W9XUP, was an FM station, because it actually was a high-fidelity AM station, and an example of what was commonly known at the time as an "Apex" station.

Apex stations like W9XUP transmitted using Amplitude Modulation (AM) signals, however they also generally employed wider bandwidths than standard AM stations like KSTP, thus providing for greater frequency response. In the late 1930s there was a mixture of Apex and FM station operating experimentally. There is limited information about W9XUP, although it is included in Broadcasting Yearbook annual Apex station list as of January 1, 1938. ("High Frequency (Apex) Broadcast Stations in the United States" (Authorized by FCC as of January 1, 1938), Broadcasting Yearbook (1938), page 290) A station representative later stated that W9XUP began regular operation on May 23, 1938. It was originally on 25,950 kHz, moving to 26,150 kHz on December 20, 1938. ("Shunt-Excited Antenna Used by U-h-f Station" by Conald M. Miller, KSTP, Electronics, May 1939, pages 44-46.) Most of its programming consisted of retransmissions of KSTP (AM)'s broadcasts

I also removed the statement that W9XUP "continued regular broadcasts until at least 1944", as there are no records of W9XUP existing after 1939. In 1940 the FCC determined that FM transmissions were superior to AM transmissions, so the Apex stations were eliminated at that time, and a commercial FM band established in 1941. Although W9XUP is included in the January 1, 1939 Broadcasting Yearbook annual Apex stations list ("High Frequency (Apex) Broadcast Stations in the United States" (Authorized by FCC as of January 1, 1939), Broadcasting Yearbook (1939), page 367), it does not appear in the January 15, 1940 listing ("High Frequency Broadcasting Stations in the United States" (Authorized by FCC as of January 15, 1940), Broadcasting Yearbook (1940), page 374).--Thomas H.
