OK. Great. I reviewed the site and it resulted in one more question: I noticed that WCPT's post sunset authority power is sharply reduced. I had believed that they could operate at full power until WBAP sunset.
- 30 -
Yes, they do operate at 5,000 watts until sunset in Ft. Worth. That is stipulated in their license.
The former WCPT AM 850(WAIT) also gets to stay on until Denver sunset with a reduced power of 265 watts.
During the day WAIT broadcasts with 2,500 watts with a 3 tower directional array from Crystal Lake. When the
sun sets here in Chicago they switch to 265 watts non-directional from 1 tower. Since they moved the progressive talk
format over to 820 they have been signing off at Chicago sunset, so you would not be able to hear the difference now.
However if you were listening to the format before the move to 820, you would have noticed the difference at about
Chicago sunset the signal was considerably weaker until they signed off about 1 hour later.
The number's that are listed on the link I gave you were just computer generated by the FCC and sent to all stations
to let them know that they could use those powers if they wished. Most stations don't bother with them though because
I'm sure you saw most of the authorazation's are mostly in the 1 to 10 watt range.
The problem with the PRSA's and PSSA's that station's like WCPT and WAIT use is that you can not find them in the FCC
database. They were written on paper sometime in the late seventies or early eighties and sent out to the individual
stations and they are the only one's with copies of them. They were authorized by the FCC before they computerized
everything, and for whatever reason they never included them in their database.
I hope that answers your question a little more(the way I babble on I should say a LOT more

)
If I left something out feel free to ask me.
Have a great day,
