In August of 1987 KISN returned to the airwaves as KKSN on both the old KISN frequency of AM 910 and, in February of 88, on FM at 97.1. The AM changed formats two years later but the FM continued until 2005 when it became Charlie FM. The AM 910 version came back from 2005 to 2007. Then KISN was gone from the Portland airwaves. In 2012, the internet radio station Goodguyradio.com was launched. It ended in 2014 but on May 1, 2015 KISN-LP was born and continues to bring the real oldies to Portland listeners on 95.1 FM.
