The signal is only used (as far as I am aware, a few Time Nuts
It can be justified very simply that the phase mod data on 198kHz is NOT
intended as a standard time distribution. As far as I am aware only the
frequency accuracy is covered in the NPL contract. Even that no longer seems
to be monitored and offsets published.
Time distribution is on MSF
