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.

If you took a buss how many people would sit down next to you?

The owner of the store selling the fuses. If they are littelfuses, he
might get away with it.

Okay. By that reasoning, because HD Radio sits "next to" the AM

Do you agree with that statement?

As a whole? No.

- 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

iBquity's IBOC Broadcast System is 'Intrinsic'
DRM's Simulcast Broadcast Scheme is NOT 'Intrinsic'

- That distinction is more about FAITH, than reality.

- There's no real difference between DRM's version
- (sitting next-to the AM signal) and HD's version
- (also sitting next-to the AM signal).

I still don't see the difference. Both standards are using sidebands,
adjacent to the analog AM signal.

DRM is not using a sideband; to do analog and digital requires a separate
transmitter for each on a separate carrier frequency. HD is a combined
analog and digital signal on the same carrier frequency. DRM is digital
only... if you want analog, you have to have a separate channel, close to or
not to the DRM one.

Exactly. DRM is a separate signal that can go wherever the operator
chooses. He may elect to place it next to his AM transmitter or the
regulator may force him to place it there so any interference will be
to his own service. Whatever, the signal will appear at only one point
in the spectrum. It is not a sideband of the AM.

HD, on the other hand is an actual sideband of the AM carrier. There
are two digital channels available, the primary and the secondary.
Each of them occupies 5kHz either side of the AM carrier, the primary
from 10 to 15kHz, and the secondary from 5 to 10kHz. The HD signal is
irrevocably combined with its host AM service.
