Adams Clerk of the Board of County Commissioners Reference: Monroe County Invitation for Proposal dated 6 June 1973 Subject: Television Translator System Aerodyne Quotation No. 736-14 Gentlemen: The Broadcast Field Support Group of Aerodyne Industries Inc. is pleased to present this proposal to the Board of Commissioners of Monroe County, Florida, to perform the engineering tasks and services associated with the establishment of a television trans- lator system to service the Florida Keys. In support of our proposal we offer the following brief discussion of our capa- bilities. Aerodyne Industries Inc. was founded on the basis of supplying high-quality electronic products to military and commercial customers. A natural outgrowth of the hardware aspect is the software capability within the individual divisions. The Broadcast Division has developed a software technique and capability that is unsurpassed in the Industry. Enclosures to this letter proposal detail several systems which are representative of past Aerodyne engineering efforts. Also enclosed are short resumes of several key contributing members of the Division. These and other members of our staff have had a great deal of experience with operating systems and possess both a theoretical and practical knowledge of translator system capabilities and shortcomings. The Broadcast Support Group is dedicated solely to the engineering and design of translator systems, and we have previously provided services similar to those proposed herein to numerous city, county and state agencies throughout the United States ~i Board of Commissioners Monroe County 22 June 1973 Page Two and overseas. In every case the final outcome was a successful operational system performing in accord- ance with the original design criteria. The service offered to the Board of Commissioners is a total engineering package specifically designed for Monroe County. It is aimed at providing the total population of the Florida Keys with high quality, free, over-the-air color television signals. Toward this end, Aerodyne proposes that the Engineering Services to Monroe County, Florida include, but not be limited to the following tasks. 1. Field Strength Measurements and Preliminary First Translator Site Selection The selection of the site for the first translator is of major importance in system design. Through field strength measure- ments and actual off-the-air color television reception, a limit is established to the useable signal from the originating Miami stations. Moving the first site further away from this point will decrease the quality of the signal received at the furthermost point in the system. Moving the site closer to Miami may not improve the picture quality, but will perhaps create the need for an additional relay link, thereby increasing the cost of the system. It should be pointed out, at this point, that the first site sets up the system signal-to-noise ratio. The signal-to-noise ratio of a television signal is, basically, a measure of the quality of the signal. A high signal-to-noise ratio indicates a snow-free, sharp picture. A low signal-to-noise ratio indicates a very weak, snowy picture. It is very important in systems engineering, to start with the best signal-to-noise available. This is due to the fact that succeeding stages can virtually do nothing to improve signal-to-noise, but can easily degrade it. Therefore, the first translator site sets the quality of the signal for the whole system and must be chosen with great care. 2. Population Survey A population survey is necessary due to two criteria. One, of course, is that the intent of the system is to provide quality television to all of the residents of the Florida Keys. By locating both major and minor areas of population, translator site selection is arranged to provide the best local distribution possible. ~.. ~/______-- Board of Commissioners Monroe County 22 June 1973 Page Three The second reason is due to the FCC rulings that translators may not be used for pure relay purposes, i.e. one translator cannot relay on to another without providing local television coverage. Therefore, all translators in the system must provide coverage to the population. Locations of populations, therefore, sometimes dictate translator site selection. 3. Topographical Survey Television signals are affected, in regards strength and some- times quality, by the topography of the land over which they travel. As such, hills, water, towers, etc. all have the potential of detracting from the quality of the received signal. It is expected that the Florida Keys area will have a minimal effect, but a survey must be made to verify that this is so. 4. Preliminary Selection of Additional Translator Locations Following steps 1, 2 and 3, previsouly mentioned, and in conjunction with steps 5, 6 and 8, to be discussed, a preliminary location for succeeding translator sites will be selected. 5. Investigations Into Site Availability in Conjunction with County Representatives Attempts will be made to choose sites that already fall under the county domain or can easily come under county domain at a minimum of cost. For example, if a county-owned tower is within one mile of a proposed site, the tower location will be investigated as the preferred location. 6. Discussions with Utilities and Service Agencies for Feasibility and Cost Estimates Each of the translator sites will require A.C. power, access roads, fences, etc. Meetings will be held to determine cost of electrification, etc. in order to prepare cost estimates and possibly eliminate some sites. ~/. Board of Commissioners Monroe County 22 June 1973 Page Four 7. Final Selection of Translator Sites In conjunction with steps 1 through 6 and following step 8, the final translator sites will be selected with the aim of assuring a) Quality Telecasting, b) Maximum Reliability, c) Ease of Main- tenance and Serviceability and d) Minimum Total Cost. 8. System Design Calculations An important part of any translator system is the system design calculations that predict system operation feasibility. Some of the design parameters are: Mean-free space - Calculations to determine loss of signal strength in traveling through space to determine maximum range of translators without deteriorating the signal-to- noise ratio. Radio Horizon - Television signals are limited in the distance they can travel by the curvature of the earth. The actual maximum distance is dictated by the heights of the transmit and receive towers. Fresnel Zones - Are zones around the main transmitted beam which are dictated by the frequency of the transmission and the distances traveled. For proper system operations, these zones cannot be violated. Interference Probability - System designs must be made to assure that no signals interfere with any others. 9. Systems Design This is the stage at which time hardware and peripheral equip- ment are specified. The tower heights are determined by radio horizon; the antennas are dictated by mean-free space, distance to next trans- lator, population, etc. ~/_------- Board of Commissioners Monroe County 22 June 1973 Page Five 10. Software Package As a necessary conclusion to the above, we propose to present a software package to the Monroe County Board of Commissioners which will include, but not be limited to the following: a) Cost and scheduling estimates for equipment, construction, installation, operation and maintenance. b) Preparation of detailed equipment procurement specifications. c) Preparation of plans and specifications for bids for construction. d) Preparation of documentation; prints, charts, maps, radiation patterns, population coverage, etc. e) Collation of documentation, presentation and submittal to the FCC for approval. f) Written approval from the four Miami stations to rebroad- cast their programming. g) Filing of applications for the FCC It is our firm belief that the engineering surveys and designs will prove that the system is feasible and that the resulting system will provide Grade A television coverage to the total population of the Florida Keys. We shall consider the engineering effort complete at the time that all information and documentation has been submitted to the FCC in accordance with the Commission's rules pertaining to translator construction applications. We offer to provide the requested services at a rate of $150 per man da~ plus travel and expenses, not to exceed a maximum of $5000. The software portion of the program, the documentation and preparation and submittal of the FCC applications, etc. shall be accomplished at a firm-fixed price of $4000. ~j Board of Commissioners Monroe County 22 June 1973 Page Six Any redesign and/or resubmittals or redundant work that may be required as a result of conditions that could possibly develop that are beyond our control, such as withdrawal of authorization to utilize chosen sites and the like, these shall be considered beyond the scope of this program and such tasks shall be accomplished at the before mentioned daily rates. In the event that engineering services are required either before contract award or following the completion of the program, i.e. super- vision of the construction phase of the system, these services shall also be provided at the stated daily man day rate. Aerodyne proposes to invoice the County on a weekly basis detailing the tasks that were accomplished and the effort expended during that period. We estimate that the proposed study and system design effort shall be completed within 6-8 weeks from the date of contract and the County's authorization to proceed with work. In the event that legal action should be taken by a third party against Aerodyne or against Aerodyne and the County jointly, and that such action is a direct result of Aerodyne's participation in this program, we expect the County to hold Aerodyne harmless and to make compensation for any legal fees and associated costs that might be incurred. We sincerely appreciate this opportunity to offer our proposal. We trust that the information contained in this letter will meet with your approval and look forward to working with the Board members and the people of Monroe County.
