Just an update. Checked again this morning and the
.169 node with disconnected antenna has finally been
dropped by ntp and replaced by the external pool entry.

It's taken around five days for the faulted node to be dropped,
which suggests that the crystal oscillator in that node is pretty
stable, even running open loop and unlocked to 1pps...
