Hello Riccardo,

Thanks to you and Stefan for the replies. I saw a silly error where I
had "Other setting in GNSS Time Locked Mode" ticked but the default
1Hz set in that menu. I can now order frequencies and duration on TP0
and all seems well. However I have totally failed to get any output AT
ALL from TP2. I have checked continuity from the Ublox pins to the
break out board and also tried probing direct on TP2 pin. I am aware
thet TP2 must not be held low on boot up so have booted with nothing
connected to TP0 or TP2 to make sure the probe could not be holding
TP2 low and going into "safe boot" mode with no TP2 output.

Is it a lot of trouble to post a screen shot of the settings you are
using to get output from TP2 either with TP0 or alone please? I have
taken screen shots of my settings and put them here:
