I have read and watched everything I can find on the yardstick method and remain confused. Say, in MP, Lead sets his TACAN to 3Y, T/R, A/A. Apparently Lead TACAN automatically broadcasts at 3 + 63 = 66Y. If I, as wing, set my TACAN to 66Y, T/R, A/A, however, I get no range data. I must set TACAN to Lead's ch, 3Y, to receive range data. This procedure conflicts with the material I have found that indicates Wing should set his TACAN to 66Y in this example, which also results, I guess in Wing broadcasting TACAN at 66 + 63 = CH 129. Can someone explain?
