Corrections for Seattle TV database
 

KOMO-TV Real 38, Digital (4.1)
KING-DT Real 48, Digital (5.1)
KWDK-DT Real 42?, Digital (42.1) Note: FCC database says the virtual channel is 56 but my TV says 42!
K26IC-D Real 26, Digital (7.1) Note: Channel 7.1/7.2 repeater in Silverdale, WA.

Update: March 18, 2015
KWDK-DT Real 42, Digital appears on (42.1) The FCC database is WRONG!
K26IC-D Real 26, Digital (7.1) is 3.9 miles away and had strong signal until the end of 2014. It is no longer receivable despite assurances from KIRO-TV that it is still transmitting. I suspect a reduction in power!
KCPQ (not KCPQ-DT) Real 22, Digital (13.1) is a repeater intended to provide more consistent coverage for downtown Seattle but is picked up at my (fringe) location just fine, resulting in channel 13 appearing twice in the channel list!
