WJSV Complete Broadcast Day. In the 1930s, WJSV was the CBS radio affiliate in Washington, D.C., broadcasting on 1460 kHz at a power of 10 kW. In later years, the station moved to its current dial position at 1500 kHz and boosted power to 50 kW. Over the years, the call letters changed to WTOP, WTWP, WWWT, and the current WFED. On September 21, 1939, WJSV recorded a complete broadcast day onto transcription disks and then donated these disks to the National Archives as an audio time capsule. The material on these disks is in the public domain.

The History of Portland Radio. Ernie Hopseker narrates the history of Portland radio from the 1920s to the 1990s. This program was first broadcast on KJUN 104.1 when that station first signed on from its Portland site for engineering tests.

KISN 91 leaves the air a second time. On February 1, 2007 shortly after midnight, KKSN 910 changed formats from oldies to "Talk Radio Oregon." The last hour of oldies programming was exclusively composed of goodbye songs. The last two songs played were the same as the last two played when KISN signed off in 1976: "She's Gone" by Hall & Oates and "Someday We'll Be Together" by the Supremes. At the very end, a recording of Dave Stone's 1976 signoff plays, followed by some dead air and the new format. This recording has been telescoped down to about 23:25.
KTRO-FM Flips to Spanish. On March 28, 2007, around 11:10 AM, KTRO changed formats from talk "Talk Radio Oregon 93.1" to Regional Mexican "El Rey." Note: The transition to Spanish was not smooth. On this aircheck, you will hear a miscue and a lot of dead air.

KISN Returns as an online Oldies station and virtual museum.

KLYC Leaves the Air. After serving the McMinnville community for almost 23 years, 1260 KLYC signed off due to financial hardship and the inability of owner Bohnsack Strategies, Inc. to successfully negotiate a sale of the radio station. The signoff occurred March 22nd at 1:00 PM, a time meant to symbolize the station's broadcast frequency (i.e. 12:60 PM or 1260 kHz).

2015
KISN returns again, this time as an LPFM station on 95.1 MHz, broadcasting from Mt. Scott with an effective radiated power of 2 Watts. This aircheck was recorded from my home, which is about 19 miles from the transmitter site, using a 10 element log-Yagi antenna. Reception is extremely good, considering the low power of this station. Here is an alternate mono recording of the tick-tock sound effect heard at the beginning of the broadcast. Note how much less background noise there is when the station is received in mono.
