Seansvoice said:The old tower height was 600 feet...there were forty-eight bays that covered the entire top half of the stick. Two 20,000 watt Harris transmitters into these antennae achieved an erp of 280k vertical and 280k horizontal. I remember seeing the contour map at the time, and the 100,000 watts at just under 1000 feet gave the station about 50% greater coverage than that achieved via the "World's First Broadhead Antenna" (as the stationery boasted).
I'm surprised no one has mentioned it, but when KQUE was running with "megapower" their signal would pop up at numerous places other than 102.9 for several miles around downtown. That flamethrower hugged the ground, bounced off the downtown buildings and took up a huge amount of bandwidth. The problem with the "image" signals wasn't just on cheap portables, either. On one occasion when I was on the Pierce Elevated I heard KQUE in at least eight other locations up and down the dial, all with the about the same signal strength as their assigned frequency. What a mess!
