No, the manual does not state
"DRM has a hybrid digital/analog mode".
A simulcast is not necessarily hybrid.

By that reasoning, HD Radio is not a hybrid format, because the
digital information sits *next to* the AM signal.

False.

False.

HD Radio is a simulcast format.

True, on the understanding that both programme contents are the same.

[quote]
DRM supports a number of different simulcast options. Currently the
supported simulcast modes require the use of additional spectrum outside
an assigned 9 or 10 kHz channel (Multi-Channel or Multi-frequency
Simulcast, MCS). The DRM signal can be located in the next adjacent
upper or lower channel and can occupy a half or whole channel
depending on the bandwidth option chosen.

So far nothing about IBOC.

Okay. By that reasoning, because HD Radio sits "next to" the AM
signal, then it is not IBOC either. It is a simulcast format.

Do you agree with that statement?

As a whole? No.

SFTV -aka- "Hybrid Digital" Man,

As and "EE", your above Statement is NOT Correct nor Clear
and it does not represent the Technical Specification {Facts}
of both iBiquity's IBOC and DRM. Please endeavor to be more
Factual and Accurate in your future representaions here.

Now For The Third Time :

iBiquity's IBOC Broadcast System is a Dual Mode Broadcasting
Scheme; with both the Analog AM and Digital Signals 'being'
"Intrinsic" to the Radio Transmission Process.

The Key Word Being : "Intrinsic"
http://www.answers.com/intrinsic&r=67

The DRM Broadcast System was initally designed and implemented
as a Single (1) Mode All Digital Broadcasting Scheme.

Note - Simulcasting and Analog AM Signal along with the Digital is
a 'possibility' but is NOT currently done on the Shortwave Radio
Band.

FWIW - The DRM Digital Signal 'may' be Broadcast along side
of an Analog AM Signal {Co-Channeled} -but- Both Signals are
Broadcast Separately and are 'independent' of each other; they
are NOT "Intrinsic" to each other as part of a Unified Radio
Broadcast System.

Caution - That the DRM Digital Signal has to be 'reduced' when
it is Broadcast along side an Analog AM Signal to prevent any
Interference to the Analog AM Signal.

The-Bottom-Line : Presently in the Shortwave Bands DRM
is Broadcast 'solely' in the 100% Digital Mode; as it was
designed to do.

for the third time or more - keeping it simple and practical ~ RHF

He isn't using a No. 2 pencil so the entire test is INVALID.

Please Understand that a Pure {100%} DRM "Digital" Signal;
which the majority of DRM Shortwave Broadcasting 'is' - Is a
Single Signal and hence can not be consider IBOC. They do
NOT Transmit any Analog along with the DRM Digital Signal.



Neither does HD Radio you stupid dog-****ing idiot. I am sick and

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.
