I couldn't find any information online about the KT-73, does it take serial input from an encoder or is it also grey code like the KT-76 A/C? I would think because it has mode S it would want better resolution then 100ft. Love to know if this transpoder will work directly with my new D10A. If it does, any idea which string of data it likes between thet 4 you have? Thanks again. David
