KNNN-LP is a low-power television station in Redding, California, broadcasting locally in analog TV on VHF channel 6. Founded September 16, 2003, it is owned by Venture Technologies Group. The station currently operates and markets itself as a radio station, using the audio portion of NTSC channel 6 (87.75 MHz) to broadcast audio (most FM radio receivers can receive this frequency at 87.7 on the low end of the FM dial). The stations currently airs a country formal called Hank-FM created and marketed by Mapleton Radio's Redding Radio group of stations.
KNNN-LP has a construction permit to flash-cut its signal to digital TV on channel 6 at 300 watts (formerly to channel 42 at 11 kW). By doing so, its purpose as a radio station would be defeated.
