		IBOC does allow for multiple channels, though this means taking some existing subcarriers off the air to make additional bandwidth available.
		On AM, IBOC is generally incompatible with analog stereo at all, and any additional channels are limited to highly-compressed voice, such as traffic and weather.
		It should be noted that the term 'iboc' is not exclusive to any one digital radio system (Digital Audio Broadcasting, Digital Radio Mondiale, HD Radio or others), although each may use a proprietary and incompatible implementation.

		The protector of network (he arises protective) of those IBOC transmitter with the Lensa seal counts on a circuit of protection against transientes of network made up of coils and varistores of metallic oxide of high capacity, those that offer a high protection to the equipment before abrupt variations of network (tips).
		The digital emission of the IBOC transmitter of Continental Lensa is predicted to the use of the equipment in the Digital condition, In Band on Channel, in terms of bandwidth and of distortion of phase.
		There are IBOC transmitter of our no factory that do not have a distortion by intermodulation smaller than two percents to nominal power and eighty and five percents of modulation with 1,000 and 400 Hertz, 1:1.

	[RT] IBOC and such
		This is a mantra that has been repeated so many times by the IBOC proponents that now just about everyone believes it, but saying it over and over doesn't make it a fact, just a marketing ploy.
		When hybrid IBOC is turned on, trashing of the analog service begins immediately, but any potential return from the digital service is still years down the road.

	IBOC
		IBOC stands for In-Band-On-Channel, which is a generic term for a way of getting from analogue to digital without an interruption in service.
		IBOC can be applied to both AM (medium wave) and FM (VHF) bands.and of course has a purely digital mode as well once the changeover has been completed.
		IBOC has caught the imagination of some radio stations in Europe and a long term test is being carried out on the VHF-FM band in the Swiss valleys.

		A new IBOC exciter and power amplifier are added, as well as a final combiner, which is used to combine the output of both transmitters at the entrance to the antenna system.
		Begin with the IBOC standard that the transmitted RF power for the digital signal should be 22 dB less than for the analog signal.
		In the second option, the analog and digital are combined at the output of the exciters, and the resulting complex signal is amplified by a common RF amplifier.

	C. Crane Company - AM Radio And IBOC
		IBOC differs from XM and Sirius satellite radio in that it is intended to work on the same bands that you already listen to.
		One of the reasons, IBOC was chosen as the optimal digital technology for the US, has to do with the ability to keep stations at the current locations on the FM and AM dial.
		IBOC will allow broadcasters to keep their current station settings by essentially sandwiching the digital signal within the analog signal.

		These tests were the first time that an IBOC FM system successfully passed a hybrid (both analog and digital) signal over a radio station's antenna and transmitter without affecting the host analog signal.
		The IBOC approach will allow broadcasters to introduce digital audio programming to listeners on their current dial positions using existing transmitters and antennas.
		IBOC DAB is both backward- and forward-compatible: current AM/FM receivers will still be able to receive the existing analog signals in the new system.

	Normalizing The IBOC And FM/AM-Analog Audio Signal Paths
		While the IBOC path offers a wider dynamic range, one that approaches the CD, it makes sense to employ some level of dynamic control so that a consistent and pleasing audio level is presented to the listener.
		This is due to the fact that processing for IBOC is not penalized by high frequency limiting the inverse of the preemphasis curve, which drives the presence and treble frequencies into heavy processing.
		For IBOC the offset can be done in one of two ways either the receiver manufacturer can choose to increase the level of the digital by 4.5 dB or decrease the level of the analog by 4.5 dB.

		IBOC technology lets broadcasters deliver simultaneous analog and digital versions of the same program on their assigned frequencies.
		Although interest in IBOC digital radio was strong once the benefits were explained to them, consumers were largely unaware of the technology at the time of the survey.
		Fifty-eight percent of consumers were unaware of IBOC digital radio, and only 35 percent could correctly identify the proper explanation of the technology from a list of descriptions.

	Not sold on IBOC
		IBOC FM must be 99 percent compatible with the current FM stations or it's back to the drawing boards.
		IBOC AM has to exceed FM and not simply be "FM-like." If all of the efforts spent on IBOC were instead directed at complex DSP algorithms, AM noise-blanking systems, diversity antennas and AMAX quality receivers, then analog radio would exist and thrive with even higher quality than it does today.
		IBOC must be a factor of ten better than analog in order for the general marketplace to want it.

	The path to IBOC
		Now that CES is over and IBOC has made its splash as HD Radio, many new questions are being raised just as broadcasters begin to understand the answers to the existing questions.
		Now that stations are beginning to install IBOC systems on their own, the focus changes from how to install it, to how to do what might come next.
		One audio plus is that IBOC removes the audio pre-emphasis and de-emphasis in the transmission system, which improves high-frequency clarity.

	IBOC and combiners
		The exclusion of AM IBOC from nighttime operation at present may cause a delay in getting a number of these smaller stations on the air.
		IBOC hybrid FM signals can be produced by three different methods: high-level combining, low-level combining and the use of separate antennas.
		If this method can be used commercially it could make IBOC attractive to stations that have room for another antenna on their towers and additional equipment in the transmitter building.

		Many on this list could develop a better plan than IBOC for AM (for FM too, but that's a whole different post) however, it is what we've been given to work with.
		The choice, as I see it, is opt in and take a chance that it may be made to work after a fashion, or continue on the present moribund course, because there will be no other opportunity forthcoming from our "dear friends" at the FCC.

	IBOC Update - Dec 9, 2004
		In a move that is sure to be closely watched by those pushing to advance IBOC HD Radio in the United States, digital radio manufacturers are hoping to profit from a pre-Christmas ad campaign running across 200 commercial radio stations in England.
		Because the FCC's long—awaited Report and Order on IBOC digital radio remains a work in progress, the effectiveness of RIAA's appeals is yet to be seen.
		Reid noted that while Impact 89 hasn't gone too far out of its way to promote the new service, the attention of local print and television based on the new technology has been welcome, as the positive publicity is likely to attract additional listeners and sought-after program underwriting funds from the local business community.

		iBiquity's IBOC system allows for a digital signal to be sandwiched in with a station's analog signal, along with sandwiching in the ability to offer digital data services, such as wireless broadband Internet.
		He says that the additional bandwidth hogged up by IBOC broadcasts will blot out distant, but receivable, stations heard on second and third adjacents (frequencies that are two and three steps (.1 Mhz) on either side of an IBOC digital station.
		Further, the IBOC signals will probably be just as rife with commercials as analog AM and FM since they're not subscription services.

	IBOC Update - Jul 7, 2004
		In addition to IBOC digital developments, the BE seminar will cover transmission technologies, installation and integration, antenna technologies and field reports.
		A view expressed with near unanimity is that new rules governing IBOC be as limited as possible, in order to allow IBOC technology to develop and evolve in an innovative fashion.
		Such a process would require AM stations that wish to commence nighttime operation with an IBOC digital signal to notify in advance both the FCC and any co-channel or first-adjacent station that might be affected by the IBOC operation.

		The reply to him from Tom Ray, WOR's Corporate Director of Engineering, was that WOR's IBOC sidebands do not extend more than plus/minus 15 kHz from the carrier and, according to their spectrum analyzer, that they were not and never were splashing beyond that.....and that "receiver overload" was the cause of the 740 interference.
		IBOC is a way to piggy back a digital audio signal onto an existing analog signal.

	Re: [IRCA] WQAM 560 IBOC off.
		Remember that from the point of view of these stations, IBOC has not even been implemented yet, and there is zero expectation that the public "has a clue" about it.
		I believe the marketing strategy is to have it up and running, with the bugs worked out (as far as that can be done, from their POV) and then, unleash the big ad campaign and un-cork the receivers into the marketplace.
		Listeners (not DXers) who care to write their _local_stations_ who are using IBOC, with comments about the signal quality etc., probably have a good chance of having those letters noticed by station management.
