===Forays into FM===
The station had an experimental [[frequency modulation|FM]] transmitter by 1939.<ref>{{cite web|url=http://www.oldradio.com/archives/dial/1939fm.htm|title=1939 "FM"|website=www.oldradio.com|access-date=May 2, 2017}}</ref>  W9XTC at 26.05&nbsp;MHz operated for several years, but by 1944, was only being activated intermittently.<ref>{{cite web|url=http://members.aol.com/jeff560/am9.html|title=AM Broadcasting History - Various Articles|date=March 28, 2007|access-date=May 2, 2017|url-status=dead|archive-url=https://web.archive.org/web/20070328131002/http://members.aol.com/jeff560/am9.html|archive-date=March 28, 2007}}</ref>  Local stations [[KSTP (AM)|KSTP]] and [[WCCO (AM)|WCCO]] also experimented with FM broadcasts around this time.

Once the modern FM band was established, WTCN attempted again to broadcast on [[KTCZ|WTCN-FM]] 97.1 from 1947 to 1954. However, few people owned FM receivers in that era and the FM license was surrendered in 1954.
