WPTF

WPTF (680 AM) is a commercial radio station broadcasting a news/talkradio format. Licensed to Raleigh, North Carolina, the station serves the Research Triangle area. It is owned by the Curtis Media Group, with studios on Highwoods Boulevard near Interstate 440 in Raleigh.

WPTF's transmitter site is a three-tower array off East Chatham Street, near Maynard Road NE, in Cary, North Carolina. Along with WBT in Charlotte, WPTF is one of two North Carolina AM stations powered at the maximum 50,000 watts. However, WBT is a Class Aclear-channel station and has more protections from other stations than WPTF, which is classified as Class B. WPTF's daytime signal is non-directional from a single tower. It switches to a directional signal at night from two towers to avoid interference to other stations on 680 kHz. Even with this restriction, at night WPTF can be heard across much of the Southeastern United States with a good radio.

WPTF is relayed by four FM translators: W225DF (92.9 MHz, Raleigh), W251CA (98.1 MHz, Rolesville), W253CY (98.3 MHz, Cary) and W298DB (107.5 MHz, Smithfield).
