I haven't been able to get into the sat either in FM or linear. And I work AO-7 and VO-52 regularly as well as the FM birds. Frustrating so far but I will keep at it.

I would love to see how much easier it would be to use with the tone turned off. Either that, or leave it in linear mode all the time.........
