The PPM  is a  powerful receiver which is designed to pick up the sub
audible symbols being transmitted by radio and TV stations
Think of it as an  Fm  station which transmits in stereo  a regular am/
fm cheap radio does not hear the stereo signal but  a better grade one
will.

Same ideal behind Digital AM/FM  transmissions   there known as IBOC
In band on channel  the digital signals  ride on
same carrier wave the analog does. so depending which radio you have
you can hear it all analog and digital or just analog.
