The old AM format was happy with cca 200Hz bandwidth to recover the time information, which was utilized in many professional receivers, which used a crystal filter for 60kHz, for the PSK format the required bandwidth is at least five times wider, so crystal filter 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).
