[BC] HDTV rollout wrinkle

[Reader]

Philadelphia's Channel 6 got angry viewers and bad press during the 
transition to digital only transmission. Over the past weekend, it 
quadrupled its TV signal.

The FCC granted an STA for six months, but the station will seek 
permission to make it permanent.

One columnist writes "The weekend's action confirmed that the FCC 
underestimated the necessary digital-signal strength in engineering 
models. Those models, experts have said, were based on outdoor 
antennas, which many homeowners in the Philadelphia area lack.
