Over the years, several Seattle area stations on regional frequencies have been boosted to 50,000 watts day and night. They all have to use directional antennas at night but I was surprised Seattle has nearly the number of 50,000 watt outlets as NYC (7) and the same as Chicago (6).
710 KIRO......Class A - Directional at night
950 KJR........Class B - Directional day and night
1000 KOMO...Class A - Directional at night
1090 KFNQ....Class B - Directional day and night
1380 KRKO....Class B - Directional at night (Everett)
1520 KKXA....Class B - Directional day and night (Snohomish)
And there are three other stations that run 50,000 watts in the daytime...
770 KTTH....50,000 watts days/5,000 watts nights
820 KGNW...50,000 watts days/10,000 watts nights (Burien)
880 KIXI.....50,000 watts days/1,000 watts nights (Mercer Island)
