This is odd... at some point last week, the retired-22434 (New Kensington headend) was brought back! This area had been seeing 22420 since mid-2006! Wonder what made Comcast bring it back all of a sudden?
I should also note that this STAR has been reconfigured since it was decommissioned. It still serves the same area, but has a different metro map, as well as different radar cities. The forecast title is now "ALLEGHENY VALLEY AREA" as well.
