ATSC maybe EW signal from the pilot carrier

Post by VK3ZAZ »

Advanced Television System Committee (ATSC) uses eight-level vestigial sideband (8VSB) for terrestrial broadcasting.
This standard has been adopted by several countries, United States, Canada, Mexico, South Korea, Dominican Republic and Honduras.

CH 2 DVC 55.25 PILOT CARRIER 54.31 DSC 59.75

CH 3 DVC 61.25 PILOT 60.31 DSC 65.75

CH 4 DVC 67.25 PILOT 66.31 DSC 71.75

You also need to be aware that most (all) 50 MHz yagis have more gain off the back than out the front when used at this frequency.
