Yep, CBU is stronger and always will be. Just because Radio-Locator thinks 105.7 is 'clear' doesn't mean it is. The contours for British Columbia stations go much farther than most people think. Victoria is clear as a bell along the water as an example.
OTOH, La Estacion de la Familia also applied for a 95.5 in Sunnyside WA per the translator auction, to relay KDYM-1230. They already have 93.7 K229AD (which upgraded to 99W).
