it could be that the intention was good , but there is no reliable
"atomic clock" and the company which promised the chip still no t
delivered any usable, as I learned from two of my clients which are in
the were business of making "atomic clocks"

The old AM format was happy with cca 200Hz bandwidth to recover the

would be problematic and much more costly, the higher required
bandwidth brings also more noise ....actually where is the advantage
of the new modulation scheme?
The changes were made to make today's consumer "atomic clocks" more
robust, not to help any kind of "professional" receivers (whether time
or frequency).
