I tried all the modes and the TUNE and MOX button stay grayed out on all modes except for CW on 60 meters which I know is not correct..
One thought is whether you are within your country's designated 60m bandplan? and have you tried a factory reset ? Have you also had the 60m band allocation added to the 3000 ? Depending what country you are in, flex will send you a file which will "add" the 60m band to your flex and you can only operate within the green blocks indicated.
