Hello, In "CONFIG "menu, i've modified, by error, the "PTT RLS" parameter; old value was ??? and now i've set to "002". I don't find on my K3 (#1212) manual rev C1 the use of this parameter. I know i could reset to the previous parameter setting, but i would prefer to know the significance of "PTT RLS". Thank you for your help. An Happy New Year! 73 QRO fr Rudolf, HB9ARI
