Regional Mexican radio station in Salem, Oregon, United States

KZGD (1390 AM) is a radio station licensed to Salem, Oregon, United States. The station, founded in 1934 as KSLM, is owned by Iglesia Pentecostal Víspera del Fin and broadcasts a Spanish Christian format.
History
The beginning
The station was founded in October 1934 as KSLM, a 100-watt daytime AM station broadcasting on 1370 kHz in Salem, Oregon. Owner Harry B. Read added nighttime operation in 1935. In May 1937, the Christian Science Monitor made special note that KSLM's careful commercial policy stood "as a barricade holding questionable advertising material from the ears of listeners". Read had earlier started Portland, Oregon radio station KXL and would go on to found the Salem Electric utility cooperative in 1938.
In September 1937, KSLM was one of several Pacific Northwest area stations to join the Mutual-Don Lee Broadcasting System. KSLM changed frequencies to 1360 kHz on April 28, 1939, which allowed for a power increase to 1,000 watts during the day and 500 watts at night. In 1940, the nighttime signal was raised to match the daytime power of 1,000 watts. On March 29, 1941, KSLM changed frequencies again, this time to the current 1390 kHz.

Why this record matters
The phrase “regional Mexican radio station in Salem, Oregon, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q6340766. Authority coordinates are 44.995, -123.071. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1390, 1934, 1370 and 1935.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
