LOCKHART" Subject: 800 MHz TRUNKED RADIO SYSTEMS Date: Thu, 25 Jun 92 15:31:13 -0700 Warning. This e-mail is long. The file is approximately 77,000 bytes. The original post asked for advantages/disadvantages on public safety 800 MHz radio systems. The following information was assembled to help non-technical personnel grasp the concept of 800 MHz radio technology. This is an apology you radio systems engineers and radio technicians who already have this information. I hope I did not mislead you. But then again, all of you except the original poster and those who posted to usenet asked for this information. There are those of you who did not ask for this information. If you posted to usenet, your name in included to receive this information. It seemed appropriate to include you since you contributed to my information base. If you object to this, please accept my apologies. If you are happy that you are included, YOU ARE VERY WELCOME. Why did I gather all this information on 800 MHz Trunked Radio Systems? Several years ago I heard rumblings that the University of California applied for (5) 800 MHz public safety channels and was considering the procurement of an 800 Mhz Trunked Radio System for its 9 campuses and 4 hospitals. I had little knowledge of 800 MHz trunked radio systems. In due time, many of the Telecommunications Associate Vice Chancellors, Directors, Managers and Radio Technicians were coming to me for information (read: everyone remembers the loud mouth). Sales personnel do not know much about these types of radio systems (except that they cost a lot of money) and rumors were running amuck. The up-front cost of a system is megabucks. E-GADS, WHAT IS ONE TO DO? I asked the senior engineer from E. F. Johnson, Ericsson General Electric and Motorola for information. The approach was: I am a trunked radio illiterate. Do you have a course in 800 MHz Trunk Radio Technology? Send me "Trunking 100 and Trunking 101". Leave no stone unturned. They did and they didn't! I received enough information to occupy 2 months of steady reading. No stone was unturned. It didn't take long to discover that this job was bigger than me. I threw in the towel, I cried Uncle. One of the first things that came to light was the need for a consulting team to gather information on the current systems, document current deficiencies, write bid specifications, help with bid evaluation, bid procurement, write a contract and monitor construction of the system. The University of California 800 MHz Trunked Radio Committee accepted my recommendation and we choose a consulting team. Currently we are developing bid specifications for a coordinated University Wide 800 MHz Trunked Radio System. Since I undertook the study to become familiar with these types of systems, the committee appointed me project coordinator and technical advisor. The project manager duties belong with someone in the University of California, Office of the President, Telecommunications (in Oakland, CA). We even put on a 1 3/4 hour seminar to help the Telecommunications Associate Vice Chancellors, Directors, Managers, Radio Technicians and other radio personnel understand :the good, the bad and the ugly of 800 MHz Trunked radio systems. The moderator is Mr. Jack Daniels. (Nice name HUH)? Mr Daniels is a radio communications consultant and President of The Jack Daniels Company. "JD" did a nice job of describing the disadvantages/advantages of all three radio systems. The seminar was video taped (VHS) and is available for a cost of $50. That includes the cost of shipping and handling. Send your written request to me via snailmail on your company letter head to the address in the signature of this e-mail message.

I have some information on trunked radio systems that may be of interest to you. ~jack_ WHAT IS TRUNKED RADIO FROM J. LOCKHART A. WHAT IS TRUNKED RADIO? June 14, 1990 A trunk radio system can be viewed like a "telephone switchboard in the sky". The trunking concept disassociates the user from a dedicated radio channel. Trunking is a computer controlled system whereby groups of users with a common interest can share a radio system. They are on solitary and dedicated talk channels. In fact, a trunk radio system is much like the land based telephone system. Land based telephone or its cellular radio extension consists of a dedicated person-to-person conversation sharing facilities with others. In trunking, groups of users talk together much like the old party line telephone system. Trunking systems have many specialized options such as paging and telephone interconnect that adds flexibility to the System. The point is that the radio channels are not dedicated to the users group. The users are in groups or systems and their radio channel use is transparent to the users. In this way, traffic sharing improves radio spectrum utilization. The benefit is both the intermittent use of channels and the time of day demand shifts of user groups. For example, on a local Government system during normal working hour Utility, Public Works, and Administration typically may have higher volume communication needs lower than Police, Fire, and Rescue users who may have relatively lower communication needs. During the evening and night time hour of high Public Safety incidents, the operating groups of Utilities, Public Works, and Administration are normally shut down with little or no demand for communications. Because of its computer controlled nature, a specific compensated feature exists. For example, a group may be altered and integrated into larger groups comprised of groups from different agencies. The trunking system could consist of only public safety, a whole City-Wide system, a Utility system, or a shared ownership system between governmental entities. This is referred to as partitioning a system. C. WHAT MAKES TRUNKING DIFFERENT? Trunked radio systems are different From conventional radio systems in several key respects. o The first characteristic is a large up-front cost. Although recently there have been some modifications regarding a lower entry level, there remains a higher up- front fixed cost than most conventional systems. o Unit add ons (mobile, personal, and control station radios) are locked into the land based vendor or its licensed agents. Therefore, you cannot do extensive comparative shopping after making a commitment on the land based system supplier. o No one particular user group directly owns or has claims on the radio frequency or hardware; it is shared by the groups. This means the groups have a common ownership (system controller). o The add-on units can be more expensive than typical low band, high-band or 450 MHz units because of their locked- in nature and their more sophisticated computer controlled capability. However, low end trunk units can be purchased for approximately the cost of high end convertional system units.

Trunked radios (sounds like a Motorola system your friend has) has a series of repeaters at a single site. One of the repeaters is a control channel with a continuous stream of data coming from it. The mobiles read this data stream to determine the status of the site. When the mobile wants to transmit it sends a data stream to the control repeater which in turn assigns the mobile which repeater to connect to. Each time the repeater unkeys the assignment may change. The sites may have up to 20 repeaters linked through the central controller. The 3 beeps mean that a channel assignment was made. Each radio is given an individual unit id as well as a fleet id for all of the units in the company. Each fleet is unique from every other fleet. From the mobile unit there is no way to monitor other conversations on the channel. The control channel regualtes traffic flow. Telephone interconnects are also handled through the control channel. A repeater is linked through the phone line and attached to the mobile. Depending on the radio a full duplex conversation can then be started. Motorola is in the process of linking trunked (SMR) sites together with data systems to provide a nationwide data communications netwrok with mobiles. Trucking companies are the primary target for this service. Non Motorola systems use a different approach. The repeaters at the mountain site each transmit a short burst of carrier at 30 second intervals. The mobiles then determine which channel is available and connect through a free repepater. Almost all of the smarts in these systems are in the mobile. The Motorola system has smarts in the radio and in the central controller at the repeater site. -- =============================================================================== Bob Wood WA7MXZ bobw@cc.usu.edu Utah State University bobw@usu.bitnet Chemistry and Biochemistry tel.

When 'idle', all the radios listen on one common control channel; the base station or repeater transmits a constant signal on this frequency (this signal contains information about the base station, such as what frequencies are available from it; the receiver can also use this signal to, for example, measure the strength of signal from the base/repeater and so decide whether the signal is good enough to give an acceptable service quality). When you hit the transmit switch, the repeater & mobile both agree on a frequency to use, tune to it, and you get your link. When you de-key the transmitter, the frequency you were using is released for use by another person. If you are out of range of the repeater, you cannot transmit. This has advantages where people drive from one area to another; with normal CTCSS-type radios you can transmit on a frequency allocated to someone else if you happen to move into a different geographical area; with a trunked system, unless the repeater 'gives you permission' to transmit, you do not get a slot and your TX is disabled. Its also possible for the mobiles to dynamically tailor their power output on the basis of the signal received on the control channel; this reduces 'spill-over' between regions and allows frequency re-use on a finer scale. This, and the dynamic frequency re-use, result in greater efficiency of spectrum utilisation (something we must encourage, since it helps to take some of the pressure off *our* bands!). The 3 beeps are produced when your transmitter has moved to a frequency under command of the repeater, and you are allowed to start speaking. Because its all digitally controlled, the control channel can be used to broadcast paging-type information to the mobiles. Theres also the ability to interleave voice and data; the control channel may be used to send special alerts, group pages etc. This is how the 'who called you' information can be passed. Its also possible for a user to 'ping' each mobile to see if he has his radio switched on or if he has switched off... Big Brother is watching.....! Another big advantage to the users of such a service is that its harder for people with scanners to listen in, since the frequencies in use change between 'overs'. In order to follow such conversations, you would have to have a receiver that could decode the digital squawks and work out which frequency to tune to. Finally, the best thing (from the perspective of the service-provider) is that you can account for the time each registered user has spent talking, and then invoice him for it every month.....! Here in the UK, a trunked system has been established in the frequency band 174-216MHz following the total closedown of VHF TV broadcasting some years ago.

A trunked radio system is more like a cellular radio network. All the repeaters are linked to an exchange and the system has automatic channel selection and direct dialing. You can have a private conversation with another unit or an open-channel "round-table" between several units. Some systems even have access to the public telephone network. A trunked system usually has several channels at one repeater site. Usually the main difference to a cellular network is that you don't have hand-over, i.e. when you get to the boundaries of the coverage area of one repeater the QSO ends. the trunked systems tend to be more limited when it comes to the service area of one operator, too. > >-Steve Schallehn KB0AGD > Kansas State University Benjamin OH3BK >From usc!cs.utexas.edu!asuvax!anasaz!qip!john Thu Oct 18 09:44:55 PDT 1990 Article 22170 of rec.ham-radio: Xref: orion.oac.uci.edu rec.ham-radio:22170 rec.radio.shortwave:3732 Path: orion.oac.uci.edu!usc!cs.utexas.edu!asuvax!anasaz!qip!john >From: john@qip.UUCP (John Moore) Newsgroups: rec.ham-radio,rec.radio.shortwave Subject: Re: CBS news irresponsible Message-ID: <5058@qip.UUCP> Date: 16 Oct 90 17:16:37 GMT References: <12493@chaph.usc.edu> <7500034@hpfcso.HP.COM> Followup-To: rec.ham-radio Organization: Anasazi, Inc.

The others aren't too different, I'm told. Typically there are at least 4 channels in a trunking system. They are really repeater pairs; most often in a small system, all the repeaters are at a single location on a good hill or tall building. One channel is the control channel and continously transmits digital codes (3600 baud, if I remember right). In a Motorola system, the control channel shifts between the repeaters in the system every 12 hours to even out the wear on the equipment. Larger systems (like San Diego's 14-channel trunking system) will have multiple control channels, usually spread around different sites for better coverage. When a mobile (or portable) is first turned on, it scans all the channels in its system until it finds the control channel. (If it can't find it, you'll get an error indication.) When you key the radio to make a transmission (after an idle period), the radio sends a quick digital request containing your unit id and the 'call group' of who you want to talk with to the trunking controller, which is listening on the input of the repeater that is the control channel at that time. The controller selects an idle repeater channel, and then transmits a command that tells your radio to switch to that frequency. If all channels are busy, you get an error indication. All the other radios in the selected talk group will also switch to that frequency. (A talk group may be everyone on your system, just a few units, or one specific unit. It's completely programmable.) While the conversation continues, you'll all stay on that frequency. After a configured idle period (which can be short or long), you'll all return to the control channel, freeing up the repeater. Whilst you're on the talk channel, a continuous subaudible digital code (63 baud? don't remember!) is sent to confirm that you're on the right channel and that you should stay there. It can also instruct you to switch to another talk channel or to return immediately to the control channel. MDT (Mobile Data Terminals), alphanumeric pagers, and mobile status indicators (in service, out of service, man down, emergency, hijack, etc) can operate on the digital control channel without needing to allocate a talk channel, although in a busy police system, it's likely that MDTs have their own channel. It is possible to poll a mobile to see if it's in service; it's even possible to reconfigure the mobile remotely in the more advanced systems. I see no reason to believe that it is impossible to remotely command a mobile to transmit, but I don't think that would be practical as an eavesdropping technique, since typically the microphone is out of the circuit unless the button on the mic is pushed, and because most mobiles have blab-off timers to prevent a wedged microphone from jamming a channel for long. It could be done, though. The voice transmissions are normally standard 5 (or 3) kHz deviated FM, but they can be digitally encrypted if the system is so equipped. That's pretty much separate from the trunking function. (As a side note, the Motorola digital encryption is done by digitizing the signal using a CVSD coder doing the A/D/A conversion; as I recall, it's like a 12kb/s code. To me, it sounds really muffled - too low a sample rate for my taste. Obviously they had to do that to fit it into standard channels.) I understand that the Johnson and G.E. systems work similarly, but don't leave the controller transmitting continuously. They may use different baud rates too. To monitor a trunking system on a scanner, you pretty much have to program all the frequencies into your radio. In the US, you can get them from the public copy of the station license. However, if the system gets busy, and the idle homing timer is set short, you'll have a lot of trouble finding a specific conversation. I think it would be really cool for someone to make a trunking decoder that could be attached to a scanner that would instruct it to follow a specified bunch of talk groups as the channel assignments took place. No doubt it'll cost a fortune. In the mean time, the only technique that occurs to me is to get a used trunking radio and pursuade a radio tech to program it the same as one of the official radios.

In my opinion it is an implementation of the MPT 1327. This standard was defined by the British Ministry of Post and Telecommunication (MPT), Department of Trade and Industry, Radiocommunications Division in 1988. The standard was overtaken by several European states, at least France and Germany. In Germany the "Deutsche Bundespost Telekom' has licensed in several regions (e.g. in the "Ruhrgebiet") trunked mobile radio systems. To the technical part of the system: (I try to summarize the informations I have) - Structure of the system: cellular; if necessary several cells are combined to a big system ofr covering an area. - Diameter of a cell: 10 - 25 km for big areas 5 km for industrial zones - separate channel for signalling data; e.g. connection establishment, exchange of ID's ... - Speech transmission analog - Data transmission: 2400 bit/s, FFSK ("0" - 1800 Hz; "1" - 1200 Hz) - Signalling data is transmitted digital with 1200 bit/s - Transmitted power: < 15 W erp (in Germany) - Frequency range: 410 - 430 MHz (in Germany); the standard allows a freq range from 50 to 500 MHz - Access to the Signalling channel: S-ALOHA - possible call types: point-to-point, 'group'-call, broadcast, conference, call redirection, priority calls, emergency calls - possible access to the telephone system (with tradeoffs caused by the half duplex in TMR) There are a lot of different manufacturer for these units, the following list is a summary of the manufacturer I know and is not ment as an advertising in any sense.

In my opinion it is an implementation of the MPT 1327. This standard was defined by the British Ministry of Post and Telecommunication (MPT), Department of Trade and Industry, Radiocommunications Division in 1988. The standard was overtaken by several European states, at least France and Germany. In Germany the "Deutsche Bundespost Telekom' has licensed in several regions (e.g. in the "Ruhrgebiet") trunked mobile radio systems. Whatever it is, I'm absolutely sure it isn't anything even close MPT1327/ MPT1343. Basically the MPT system behaves quite like your plain ole' analogue cellular. On every site there is a control channel telling the mobiles all sorts of tales about the system. In call setup the mobile contacts the system on the control channel and a traffic channel isn't allocated for the call until the B party answers (this is the main difference from cellular). However, when the call is set up, it stays always on the same channel. What I remember of the Motorola system from an article somebody posted here (or in comp.dcom.telecom) a while ago, it really trunks the calls. Every transmission starts with a short signalling sequence where the mobile IDs and tells the system where to send that transmission. No special traffic channel is allocated to any call but you have to wait until the signalling ends. So, in my opinion, it sounds like Motorola. BTW. we have a MPT 1327 system called AutoNet here in Finland on 450 MHz. It is operated by the private regional telephone companies. In 1989 when I started with my current job, I suppose I was the first man in the whole organisation to be occupied full-time in setting up AutoNet...;-) 73 de Benjamin OH3BK -- Pentti "Benjamin" Gronlund OH3BK@OH3RBR benjamin@ee.tut.fi Gr|nlund_Pentti_OMNI (elisa) Life member of IAAA, the International Association for Adjustment Aces "M{ olen mies, jolle ei koskaan tapahdu mit{{n" FROM J. LOCKHART To: Dave Tomcheck Subject: [Considerations for trunking system] Date: Wed, 23 Aug 89 14:37:38 -0700 From: Jack Lockhart Dave, I am sending you a paper titled: "Considerations For Acquiring A Public Safety Trunk Radio System." It should follow this mail message. We can talk about it when you have time. I think we should look into getting a consultant as soon as possible. We need to begin the process of building up confidence in this system. I recommend that we ask an independent consultant for a RFQ on the newly proposed 800 MHz., trunking system. I will be sending you a paper in the next couple of days to justify my position. The title of the paper is, "CONSIDERATIONS FOR ACQUIRING A PUBLIC SAFETY TRUNK RADIO SYSTEM". I think the time is right for us to be aggressive with this issue. If we are not aggressive and assume control, we may pay for it later. Perhaps other campuses will follow our lead. More later. ~jack_ TITLE: CONSIDERATIONS FOR ACQUIRING A PUBLIC SAFETY TRUNK RADIO SYSTEM INTRODUCTION A trunk radio system is a radio system classically different from most conventional land mobile radio systems. This article will explore some of the key differences between trunked and conventional radio systems. These differences require purchases of trunked radio systems to explore alternate means of acquiring these systems. This article will present some of these techniques. While this article addresses systems government procurement acquired through negotiated, qualifying, proposal or competitive procurement policies, these techniques can be applied to systems which are not required to follow competetive procurements. For example, SMRs, and Utilities systems. WHAT IS TRUNKED RADIO? A trunk radio system can be viewed like a "telephone switchboard in the sky". The trunking concept disassociates the user from a dedicated radio channel. Trunking is a computer controlled system whereby groups of users with a common interest can share a radio system. They are on solitary and dedicated talk channels. In fact, a trunk radio system is much like the land based telephone system. Land based telephone or its cellular radio extension consists of a dedicated person-to-person conversation sharing facilities with others. In trunking, groups of users talk together much like the old party line telephone system. Trunking systems have many specialized options such as paging and telephone interconnect that adds flexibility to the System. The point is that the radio channels are not dedicated to the users group. The users are in groups or systems and their radio channel use is transparent to the users. In this way, traffic sharing improves radio spectrum utilization. The benefit is both the intermittent use of channels and the time of day demand shifts of user groups. For example, on a local Government system during normal working hour Utility, Public Works, and Administration typically may have higher volume communication needs lower than Police, Fire, and Rescue users who may have relatively lower communication needs. During the evening and night time hour of high Public Safety incidents, the operating groups of Utilities, Public Works, and Administration are normally shut down with little or no demand for communications. Because of its computer controlled nature, a specific compensated feature exists. For example, a group may be altered and integrated into larger groups comprised of groups from different agencies. The trunking system could consist of only public safety, a whole City-Wide system, a Utility system, or a shared ownership system between governmental entities. This is referred to as partitioning a system. WHAT MAKES TRUNKING DIFFERENT? Trunked radio systems are different From conventional radio systems in several key respects. o The first characteristic is a large up-front cost. Although recently there have been some modifications regarding a lower entry level, there remains a higher up- front fixed cost than most conventional systems. o Unit add ons (mobile, personal, and control station radios) are locked into the land based vendor or its licensed agents. Therefore, you cannot do extensive comparative shopping after making a commitment on the land based system supplier. o No one particular user group directly owns or has claims on the radio frequency or hardware; it is shared by the groups. This means the groups have a common ownership (system controller). o The add-on units can be more expensive than typical low band, high-band or 450 MHz units because of their locked- in nature and their more sophisticated computer controlled capability. However, low end trunk units can be purchased for approximately the cost of high end convertional system units. THE NEED FOR A CONSULTANT When deciding to enter into the trunk radio system market, it is to the owner's advantage to have an outside consultant of some nature. You may need a technical consultant, negotiating consultant, contracting consultant, or a financial consultant. It is unusual for the owner to have all the in-house capability needed to procure and install a complex system of this type. If the owner does have all the in-house capability needed, then their activity level must be assessed to determine the time they will have to devote to the project. What kind of consultant should the owner decide upon? Following is a logical sequence to follow on how to determine the type of service that will be required. The owner must look at his organization and the time availability of the personnel on staff and consider the following questions. o Do you have adequate personnel to perform the financial analysis? o Do you have adequate personnel to negotiate and monitor the contract? o Do you have adequate personnel to follow the inspection of the construction phase? o Do you have the in-depth technical capability needed to define the needs, select the vendor, negotiate and assist in the installation of the system? Once you determine the capability and availability of your personnel, then you can supplement your staff with an appropriate outside consultant. How do you proceed to acquire a consultant? Depending on the area of expertise required, there are various professional organizations comprised of members with expertise in contracting, negotiations, or professional engineering. Usually you can find an organization whose members provide the kind of service you will require. You should shop around and arrive at a list of firms to be considered as your consultant. If you are selecting or desiring to hire a technical consultant, two criteria should receive strong consideration. First, the firm should be comprised of professional engineers properly styled and duly registered in both the state in which you operate and the state in which they reside. By selecting a firm with professional engineers, you are assured that the personnel have the proper certification and have proven to possess the necessary skills for a project of this magnitude. Secondly the consultant should be a member of the Association of Federal Communications Consulting Engineers (AFCCE). This is a nationally recogized organization with a commonalty of expertise. To qualify, the members must be registered as a professional engineer and have a substantial portion of their practice in Federal Communications Commission matters. If you follow this tenet, you can be assured that the individual being considered is not just a normal engineer attempting to perform a task while not having any creditable communications regulatory experience. The AFCCE is much akin to the communication bar. Since radio systems are licensed by the FCC, being a memher of the AFCCE certainly should give the owner additional piece of mind. Direct and indirect conflict of interest should be explored of all consultants. Direct conf1ict normally is interpreted as a business affiliation such an ownership relationship of a system supplier (hardware, services or software). Indirect conflict is normally considered a client relationship, in some form, with a system supplier. The full role of the consultant's requirements should be assessed; whether the Consultant plays only a negotiating role, a negotiating and contracting role, or a follow-up role regarding construction monitoring and contract administration. It should be discussed up front whether the owner anticipates a need for a resident inspector or resident construction coordinator since, invariably, you may become involved in building re-modifications or site acquisitions, and new construction. SELECTION OF A CONSULTANT Selection of a Consultant is a difficult task. Usually, the Consultant submits credentials, a scope of services and a compensation plan which is reviewed by a Communication Committee. However, ultimately, the relationship between the communications committee or project manager and the consultant will determine whether it will be a long term satisfactory relationship or not. A face-to-face conversation or interview is imperative in the selection process. COST VALUE OF CONSULTANTS There are several ways of structuring the fee schedule for a consultant. The fee structure can be on a level of effort basis, an on-call fee basis (retainer), or a percent of construction basis as determined by a suitable method. The Virginia Society of Professional Engineers has developed a fee curve as shown on Figure 1 which can be used to determine the consultant's fee based on the cost ot the system. This curve is applied only to the cost of equipment and installation of the system, and does not cover feasibility studies, regulatory work, public hearings, or resident activity. Typically, trunk systems are multi-million dollar procurements ranging from 1-15 million dollars. Therefore, fees will vary accordingly, dependling on the size of the system and effort desired of the consultant. Sometimes the prospective owner will be falsely led in by a major supplier who offers to "give away" consulting services. Their justification is that they know their own system and can provide the best advice on how to use the system. In reality [while they know their equipment they are in the business of optimizing the selling of equipment. A consultant would be funded by the owner and would be responsible for being sure that the owner gets the best deal possible. With independent expertise, there is parity in the business relationship. The owner must recognize in the budgetary process that the cost of consultant fees are an integrated part of the project and must be so recognized. The only decision is to determine now the funds will be deployed; for in-house resources, outside help, or rework prices from the supplier. SPECIFYING AND CONTRACTING SYSTEMS The classic method of specifying land mobile systems (such as, area & time 90/90 or 95/95 coverage reliability) do not apply satisfactorily in the 800/900 MHZ. trunk bands. This is due to the core coverage problems in the buildings and underground coverage (underground Parking garages, Mass Transit subways, tunnels, etc.), and the increasing desire of public safety systems to provide highly reliable personal coverage into these areas. It is best if the contracting personnel and the system supplier are on a parity technical base regarding understanding what is and is not reasonable. Joint agreement on the location and number of sites, and the antenna configuration is imperative. Later, depending upon what the real world results are, both sides can approach solutions in a joint manner and possibly share the costs in any supplemental activity. If special coverage into large shielded areas are required (such as underground shopping malls, metro tunnels, core buildings & large parking garage areas), innovative research and development may be required and separately installed subsystems may be required to tie these areas into the overall system. Because of the lock-in nature of the procurement, the owner must be protected in some way for future add-ons. There are at least two proven ways that the owner can be protected on a contracting basis. The first, is a type of an equal nations or favored nations (favored customer) clause applicable three to seven years after the acceptance of the procurement. In this way when the prices vary in the marketplace, the owner can either reap the rewards or the penalties as the market prices changes. Secondly, an extended discount structure can be developed dependent upon the number and types of units, or incremental dollar value. There should be penalties in the contract appropriate to the size and conditions of the contract. A small contract should not have a large penalty. Using the same theory, a large contract should not have such a small penalty that the vendor can ignore it. RELATIONSHIP AND AUTHORITY The consulting firm can basically play two roles. The consulting firm can be an agent for the owner much like an architect dealing with the contractor. The agent can speak for the owner with some limited authority; or the consultant may be a staff augmentation to the owner who already has its own project manager. Because of the size and complexity of these trunk systems, with the need for building, remodeling, and site acquisition, the project management team appears most useful when parties get serious about a trunking system. Early acknowledgement of the approved project team minimizes in most cases vendor transition problems from their sales organization to their implementation organization. TYPES OF FINANCING In large systems, there are basically three forms of financing. The owner must first decide which one is most appropriate for his organization. One approach is a lease approach or a lease/purchase approach. Secondly, progress payments with some retainer and a final payoff when the system works satisfactorily is acceptable. Lastly, third party construction/financing may be applicable. This type of financing may delay final payment of the system. An example of this is when the third party will provide the construction lending and maybe even carries the system for the use to the owner a certain period or time after system acceptance. Then, when the owner's cash flow permits, there could be a final payoff of the third party financing. CONCLUSION This paper has outlined some potential pitfalls and significant matters which a prospective owner of an 800 MHz trunk system should consider before embarking into these activities. Above all, thoroughness of planning the whole procurement and implementation process is most appropriate; considering the new technologies, the new business relationships, and the complexity of the activity. A well based technical consulting firm with expertise in Procurement, Negotiation, Project Management, and Financial Analysis will enhance a smooth transition and installation of the system.

Newsgroups: rec.radio.amateur.misc In-Reply-To: <11h6ddINNkee@network.ucsd.edu> References: <1992Jun13.233118.12067@ica.philips.nl> Organization: Clearpoint Research Corp., Hopkinton Mass. Cc: Status: RO Lyn Kennedy (lrk@k5qwb.lonestar.org) has successfully modified Motorola Radius radios to interface to an IBM PC and allow the PC to read the trunking data stream and control the radio, allowing following of trunked conversations and selective filtering and ID of specific groups and units. His PC software will also scan the band looking for trunked systems and record statistics on what channels and ids (fleet and subfleet) are in use in any systems it finds. He uses a standard PC serial port attached to the programming port on the Radius radios (the radios include a UART) and replaces the ROM in the radio with one with the special hacked up firmware to talk to the PC. His software will also decode GOLAY and POCSAG pager traffic and several types of MDT's, all using the Motorola radio as an FSK demod. R-7000's have been found to be pretty non optimum as FSK demods for this purpose - another friend has had to build outboard IF strips with special filters to get good BER (particularly on the 10 kbps cellular control channels) - Lyn also found that using the demod in the radio gave much better results than a scanner IF. This has to do with the group delay characteristics of the IF filters and with having adaquate bandwidth. Lyn posts to the network fairly regularly on alt.radio.scanner rec.radio.amateur.misc and rec.radio.shortwave (and is k5qwb). He lives in Ovilla Texas and is a self taught inventor (several patents) who has been recently working on gas field instrumentation software. -- David I.
