I live in the Cooper Mountain area and never hear KBNP at night. Over the past few nights, I’ve noticed a strong signal from KBNP. Have they officially increased their night power, or are they just not powering down to 9 watts?
KBNP’s nighttime signal strength seems to have diminished to somewhere near where it should be. I could hear it in Beaverton with severe co-channel interference from Vancouver, BC. In Hillsboro, I tried to receive the station using a loop antenna, but I was not able to null out the Vancouver station sufficiently to make that possible.
The daytime signal strength appears to have deteriorated severely. Using an outdoor loop antenna, reception is moderately noisy in Hillsboro. On a car radio, I hear interference even in places where there are no overhead utility lines. Can anybody shed light on the KBNP mystery?
