"There is only one analog station left in the Cleveland area -- W51BI in Kirtland, east of the city in Lake County, Ohio -- and I'm not sure if that station is still on the air."
From FCC records, it appears that this translator is still transmitting in analog... they have a construction permit to go digital, which expires 12/29/2011.

It appears that no firm deadline has been set by the FCC for low power (and likely translators, as well) to transition to digital.
