Keep in mind initially TACOMA was considered a separate market from Seattle.
Bellingham could have their own FOX station up there, but KCPQ would probably complain. Kinda like when KVOS was a CBS affiliate back in the day and KIRO complained. Whatcom and San Juan County should really be it's own market though.
This is a major drift off topic, but back in the 70's FM transmission facilities were all over the map: Cougar Mt., Roosevelt Hill (N. Seattle) Indian Hill (Tacoma), Three Sisters Mt. (near Enumclaw), Queen Anne Hill, Capitol Hill, Pigeon Point (West Seattle), just to name a few..
Lemme see what I can remember (this is from faded 40 year memory and third hand info, so I could be grossly wrong.....)
Roosevelt Hill: 89.5, 99.9, 107.7
Indian Hill: 91.7, 97.3, 106.1
Three Sisters: 92.5, 103.7
Queen Anne: 98.1, 100.7
Capitol Hill: 94.9
Pigeon Point: 93.3, 94.1, 102.5
Forest Park (Bremerton) 106.9
Fremont Hill/Aurora Village: 105.3
I'm at a loss for who was on Cougar exactly back then. Or who was first. I think nearly everyone went to Cougar in the '80s and Tiger in 1988 - 1990s.
You are pretty close! Corrections here:
Roosevelt Hill: 99.9 The original KNHC 89.5 transmitter site (now backup site), was on Wedgwood Hill atop Wedgwood Elementary School. KISW originated next door on Roosevelt Hill. KRAB 107.7 was one of the original stations from Cougar Mt.
Indian Hill: 91.7, 97.3, 106.1 Correct!
Three Sisters: 92.5, 103.7 I believe 92.5 has always been from Cougar Mt.
Queen Anne: 98.1, 100.7 Correct!
Capitol Hill: 94.9 Correct! Prior to moving to Capitol Hill, 94.9 was KOMO-FM via a tower next door to the old Fisher Broadcasting Building. That very 150' tower was moved to Queen Anne Hill and still to this day, makes up the top half of the current KOMO TV tower.
Pigeon Point: 93.3, 94.1, 102.5 Correct!
Forest Park (Bremerton) 106.9 Correct!
Fremont Hill/Aurora Village: 105.3 Correct!
