Think I understood and then find I missunderstood.Jan,
It seems so simple but....
It says "Again for WSPR, the Start parameter must be even (a multiple of two). For WSPR- 15, a multiple of 15.
Default: the default value is 00 which means the Start parameter is not used."
But I tried setting 10 00, seems to give a start of 10, 20, ... minutes, possibly also 00? Yes. Is this true on all firmware? I have v3.09f, it does not work like Andy says. I think the instructions are the same for all firmware on this point.
10 10 gives a 10 minute cycle starting 10, 20, ...
It does say Frame "Default: the default value is 00 which means no frame size is defined, All mode/frequency combinations are sent repeatedly in sequence. Frame must be set to a non-zero value for WSPR, WSPR".
The firmware does not let me set 00.
02 ** is possible and does give 100% TX.
Andrew, what setting were you using?

Have been looking in the manual and see that the 10 00 picture was taken from there not from Andrews own U3S.
