We had this discussion a few years ago here!

You are still wrong. The best timing receivers available are the geodetic
quality receivers that have an external frequency input. Sometimes they
are slightly modified versions of the standard geodetic receivers, but
they remain top class navigation receivers never-the-less.

Tell me a modern receiver used by a national time-lab for time-transfer to
other labs that is a bad navigation receiver!
