Sister station KQWB "Q98 FM" went on the air in 1968 and had been a Rock station for nearly its entire existence.  In 2013 KQWB moved to 105.1 FM while 98.7 FM became CHR outlet KLTA "Big 98.7"

KSUB

KSUB is run by the students, faculty and alumni of Seattle University in Seattle, Washington.  This May, 2014 article says that the station has been granted a low-power FM license but it seems that they are still internet-only at this point as there is no mention of a frequency on the KSUB website.

UPDATE:  The YouTube description of this KSUB video mentions that they broadcast at 89.1 FM.
