fact that it runs more power at night is very unusual for an AM station.
You mean to the WEST during the day! There is a local minimum at 102 degrees true, which is close to due east. At that minimum, the inverse-distance filed at 1 km is less than the equivalent of 250W ND. By pattern symmetry, there is a similar minimum close to due south. There are two more local minima that are just a whisker more severe--one to the north-northeast and one to the southwest. The pattern maximum lies to the northwest (323 degrees true). There, the field is arguably equivalent to a bit more than 11 kW ND. At night, the local maximum at 323 degrees true is equivalent to an ND signal of about 21% of 11+ kW, whereas at the pattern maximum (143 degrees true) is equivalent to more than 20 kW ND.
