Good point. It is a smaller window of time than I expected.
In fact, the official (FCC and Industry Canada) Pattern Change time for a given month is the closest quarter hour to Sunset on the 15th of the month. Which translates, for January, into 5:00 p.m. in Mount Angel, Oregon and 4:45 p.m. in Vancouver.
I'm still surprised that WX wouldn't have a better signal into the Fraser Valley on day pattern. Then again, part of it is the format. Listeners in Vancouver found XETRA annoying during CBU's talk programming in the '60s, and Wolfman Jack on XERB often bothered KING's classical music listeners in Vancouver.

This begs the question ... How far will a radio signal skip before it is heard outside the primary listening area... I couldn't find anything online to answer this question, but I am sure the "Radio West Brain Trust" will be able to educate me.
No easy answer to that one, in my DX experience. KOL Seattle was usually a problem in Burnaby at night for me back when they were 5000 watts, but they also had a really lousy night pattern. Lan Roberts once told me that he got complaints from listeners that they could not even hear the station in Downtown Seattle at Night.
All that said, KOL was one of those stations where you could hear the ground wave and sky wave phase in and out with each other. So, Seattle is definitely far enough away from Vancouver to get skip.
