I believe if you look on the FCC website and look at a record that has -DT, you'll find the DT transmitter site. But, are those records even correct now that there has been a delay. I believe the FCC site had WPVI-DT on channel 6, where it now is supposed to be and WPVI-TV should be off the air now. Or, have they gone away from the -DT and the digital stations are or will be -TV?
http://www.fcc.gov/mb/video/tvq.html . Type in some search criteria and click "Submit". A list of records meeting those criteria come up. Click on the call letters and more detailed records matching those call letters appear. The links "Region Map", "Area Map", and "Local Map" will pull up tower site maps at three different zoom levels.
The DTV Delay Act doesn't directly invalidate any of these maps, but it does delay the date when some channels move.
They seem to have prematurely marked WPVI's channel 64 DTV facility as a "superceded record".
The website at places uses -DT and -TV (or no suffix at all) more or less interchangeably. The actual digital station licenses still all specify "-DT".
A station's analog and DTV facilities are considered two separate sets of engineering parameters for the same station. They occupy two different records in the "tv_eng_data" table in the CDBS database. However, they're linked to a single "facility" record. (because the analog and DTV stations are owned by the same company, licensed to the same city, and receive official FCC correspondence at the same address.)
The "facility" record also contains the call letters. So the analog and DTV facilities must be listed in CDBS with the same calls, including any suffix. The database design doesn't allow otherwise.
But the *official* call letters, those the station is required to use on the air, are those printed on the license.
