KWPN's transmitter is off West Indian Hills Road in Norman. It broadcasts with a power of 5,000 watts by day; because AM 640 is a clear channel frequency, reserved for Class A KFI in Los Angeles, KWPN must reduce power to 1,000 watts at night to avoid interference. A directional antenna is used at all times.
