The audio channels should be monitored in Wideband FM (WFM) mode. Each audio channel uses 100 kHz bandwidth.
- The video and audio carrier frequencies listed are for the NTSC analog standard and are not applicable to the new ATSC digital (DTV or HDTV) standard.
- Some analog TV stations are offset + or - 10 kHz (.01 MHz) from the standard frequencies to reduce co-channel interference.
- The 8-VSB modulation used in ATSC (DTV) has a pilot carrier approximately 310 KHz above the lower band edge.
- Some DTV stations are offset slightly to reduce co-channel interference.
