What is the oldest college radio station?

WPRB at Princeton University ?

Nope.
Hint: By some criteria, this is the oldest radio station in the United States.

KSLU Radio St. Lawrence University ???

Several claim this distinction!

KSLU @ St. Lawrence (1922 - already given by dogspit)
WMUC @ Maryland (1937)
WPRB @ Princeton (1939 - already given by 'Mater)
WBRU @ Brown University
WERS in Boston
KWGS @ Tulsa University
WAER @ Syracuse

Though I don't have the dates for some of these, KSLU appears to be a very strong answer. WPRB may be the oldest college FM station.

The station I'm referring to isn't on this list, but gives a date before 1922. Any more guesses?

WRL at Union College in Schenectady, NY

Jersey - That's the one I had. It first went on the air Oct 14th, 1920, and began weekly broadcasts the next day. I'm not sure what the original call-sign was, but it became WRL in 1922. The station now broadcasts under the callsign WRUC.

Aug. 13, 1912. First experimental license issued by Dept. of Commerce following Int. Radio Convention and Radio Act of 1912, to St. Joseph's College, Philadelphia (3XJ, 2 kw)

1919. 5YA (WTAW) College Station TX (???)

Oct. 14, 1920. The first college radio station goes on the air at Union College in Schenectady, according to Famous First Facts, which identifies the station as WRUC. The original call was actually 2XQ, according to Radio World of June 10, 1922. In March 1922 the station was given the call WRL. [Donna Halper] According to Famous First Facts, "It instituted a series of weekly programs on Oct. 15, 1920, consisting of vocal and instrumental phonograph records. The programs were broadcast from 8 p.m. to 8:30 p.m. with a three-minute interval. They were initially heard within a 50-mile radius; this increased under favorable weather conditions. A 5 50-watt U-2 transmitter was used." - A Chronology of AM Radio Broadcasting 1900-1960
