  • It is not possible to receive digital TV audio with a scanner or AM/FM receiver.
  • Before the transition from analog to digital TV in 2009, audio from analog TV stations could be received in wideband FM (WFM) mode. Each audio channel used 100 kHz bandwidth.
  • The analog video and analog audio carrier frequencies listed in the table below are for NTSC analog TV and are not applicable to ATSC digital TV (DTV or HDTV).
  • Some analog TV stations were offset + or - 10 kHz (0.01 MHz) from the standard frequencies to reduce co-channel interference.
  • The 8-VSB modulation used in ATSC (DTV) has a pilot carrier that serves as a reference frequency for DTV receivers and can be heard on an AM or FM receiver. The pilot carrier is approximately 310 kHz (0.31 MHz) above the lower band edge. The exact frequency used may vary because the transmitted signal may be offset slightly to reduce interference.
