Hello Jarda Here's one idea. Use your logging program to make the changes. You could program the A/B change to be followed by the Ant1/Ant2 change, all at the press of one button. Just how you do this will depend on which logging program you are using. It would be easy in TR Log. I think it can be done in N1MM but I'd have to ask someone who knows the program better than me just how to do it. Good luck and 73 Bob N6WG
