	Joint Tactical Radio System
		JTRS is being developed in parts, referred to as clusters.
		The JTRS SCA originally applied to waveforms operating at frequencies from 2 megahertz to 2 gigahertz.
		The JTRS program as it was developed was basically, to me, an unachievable goal because it was looked on as being a radio replacement program.

	Defense Daily Network: Defense Industry news, analysis and business information
		JTRS will use software programs to "transfer voice, data, and video through the battlefield equivalent of an Internet browser, complete with plug-ins that allow motion and voice to move with the ‘web’ pages," says Dick Hitt, director of business development and strategic planning, Raytheon Radios and Terminals.
		JTRS’ software communications architecture (SCA), comparable to an operating system on a personal computer, was developed by Raytheon and members of a Raytheon consortium, including ITT and Rockwell Collins.
		Bridging allows a JTRS unit to be a "middle man," connecting two radios that were not designed to communicate with each other.

	NDM Article - Military Sets Less Ambitious Goals for New Tactical Radio
		JTRS, conceived in the late 1990s, was intended to eventually supplant more than 750,000 radios in the current military inventory.
		Another unplanned hurdle for JTRS was the war in Iraq, which prompted rushed purchases of thousands of new combat radios.
		JTRS originally was intended to sync up incompatible legacy radios by converting the signal in a process known as “cross-banding.” That requirement had to be watered down because it was technologically too complex, Hitt said.

	Congress Worried JTRS, Combat System Timelines Don't Mesh
		The goal of the JTRS Cluster 5 effort is to develop handheld, portable and small terminals that can be transported by individuals or aboard vehicles.
		Anna Marie Montague, a spokeswoman for the JTRS Program Office, said performance requirements for Cluster 5 are still being developed and that could affect the schedule.
		Boeing is the prime contractor for JTRS Cluster 1, which is designed to develop communication hardware for Marine and Army ground vehicles and Army helicopters.

	Defense Tech: Curtains for "Jitters"?
		Essentially, the JTRS program [known as "Jitters"] is aiming for something that’s almost physically impossible, or at least extremely expensive, experts say...
		But for the JTRS radio to be carried on missiles to provide guidance and on other platforms such as unattended ground sensors, there is no requirement for all that processing power.
		Both warfighters, outfitted with JTRS, would have the capability to host one another's "waveform", providing them with the opportunity to operate in the same part of the spectrum using the same modulation scheme, thereby achieving interoperability.

	Jittery Over JTRS, Pentagon Puts Boeing on Notice (defense acquisition, defence purchasing, military procurement)
		JTRS envisons an all service radio that is essentially a computer with a radio front end, using a new wideband networked wireless waveform that could provide mobile networked-connectivity across the battlespace while providing compatibility with the current platforms in use by the DoD today.
		JTRS is not a one-size-fits-all system, however; rather, it is a family of radios that are intended to be interoperable, affordable and scaleable.
		JTRS capabilities were already intended to be developed and fielded in an evolutionary manner, in order to provide increasing capabilities as technology development and funding permits.

	JTRS Program to Continue After Restructuring (defense acquisition, defence purchasing, military procurement)
		JTRS was scheduled to be part of many new US systems, from updated MIDS/Link 16 terminals in aircraft to remote control of the NETFIRES "missile in a box" to a key role in the $100+ billion Future Combat Systems program.
		Dennis Bauman, the JTRS Joint Program executive officer, said that Boeing had made "significant changes for the better" over the past 10 months since it was issued a show-cause over program issues that included cost controls, affordability of final product and relationships with subcontractors.
		JTRS' original "big bang" acquisition strategy, using different "cluster teams" defined by similar user requirements, is attractive in that it creates a stable core technology that can be built upon later without a lot of rework and updates.

	Tactical radio project substantially weakened
		Software-based radios such as JTRS — designed to operate as a computer network — are more difficult to protect from hackers than traditional military radios, which have customized crypto devices and are intended for individual services, not for the entire Defense Department.
		A larger concern for JTRS developers, MacLaird cautioned, should be the Defense Department’s decision to shrink the program from 32 to nine waveforms.
		The implication is that only a portion of the force will be included in the JTRS network, and the majority will continue to operate their current radio systems.

	Dr. Dobb's \| Building SCA-compliant Software-defined Radios \| September 27, 2006
		As a result, JTRS radio set developers who require FPGA or DSP devices to achieve the required levels of performance for complex waveforms and multichannel operation, are faced with two choices: either develop custom hardware and build SCA compliance into it, or buy COTS products and adapt the standard drivers and libraries to SCA compliance.
		JTRS eliminates stovepipe legacy systems where each component is so intimately tied to the next that replacing an outdated component could cause a change to ripple throughout the whole system.
		The JTRS mandates the use of the SCA that allows multiple radio types or waveforms applicable to one hardware platform as well as waveforms that are portable across all platforms.

	JTRS Cluster 5 - By Scott R. Gourley - Special Operations Technology
		The requirement for the JTRS was first documented in the mission needs statement (MNS) for the Joint Tactical Radio, August 21, 1997.
		Initial steps in JTRS program industry participation began in early 1999 with the awarding of contracts to three consortiaâ”led by Raytheon, Motorola and Boeingâ”tasking them with defining the Software Communications Architecture (SCA) that would be required by a joint service communications system.
		The JTRS JPO had already contracted to Thales Communications to do handheld radio work under the earlier "step" phases of JTRS and that work reportedly facilitated that aspect of the Cluster 2 award.

	JTRS: Reloaded, Rescoped \| COTS Journal
		Beyond those name changes, the biggest change in JTRS is a dramatic paring back in the number of waveforms to be included.
		In the early stages of the JTRS program a repository of waveforms was established, where anyone who needed a waveform because of a government contract, could go in and get it for free.
		Apparently the JTRS JPEO feels the same way, and they are attempting to persuade the Department of State to lift the ITARS restriction on the JTRS HAL, but have not been successful to date.
