There is no technical difference. Both HD radio and DRM operate on
the same principles:
- 2 separate signals
- 1 analog
- 1 digital
- the digital is simulcast "next to" the original analog signal


No, DRM is 100% digital. To run analog simultaneously you need a separate
frequency. Some testing is being done, like that in Mexico, by placing the
DRM signal on the adjacent AM channel... a station on 1060 is going to have
DRM on 1070.


And I repeat:


- HD radio works the same way.
- The digital signal sits *next to* the station at 1070.

SFTV,
