+xTim Dawson - 11/8/2017 11:28:16 AMThe SkyEcho is an ADS-B device. It does not claim to support the display of plain mode C and mode S data, and does not do so.The display of plain mode C and S data (i.e. "there is an aircraft somewhere around, at about your height, but we don't know where") is a useless feature (in my humble opinion) serving only to distract the pilot with a warning telling something they should already be assuming.
