The beacon could be seen as far away as 150 miles (240 km) on clear nights. A smaller version of the beacon, still flashing out the name of the city remains to this day, although malfunctions with the relay switch caused it to spell "P-I-T-E-T-S-B-K-R-R-H", and eventually "T-P-E-B-T-S-A-U-R-G-H" before being repaired on July 27, 2009.The tower on the roof also served as the broadcast antenna for radio station KDKA Pittsburgh which made the first commercially licensed radio broadcast on election night of 1920.
