All of this is made possible through the efforts of a highly skilled and specially trained staff working in one of our seven versatile company departments; Engineering, Electronics Assembly, Machine Shop, Fibreglass Shop, Repair & Overhaul, Quality Assurance and Administration. Company Facilities Company Facilities The Valcom Manufacturing Group, Inc. is comprised of a main manufacturing plant in Guelph, Ontario. The Valcom facility is a 46,000 square foot, state-of-the-art, fully equipped manufacturing plant. The plant is built on a ten acre property with five additional acres of land available for expansion purposes. Two acres are dedicated for testing military and commercial antennas from Low Frequency (LF) to Ultra High Frequency (UHF). Valcom's quality management system is certified as being compliant with ISO 9001:2015 by Intertek. Company Operations Company Operations Valcom's day-to-day activities are grouped into six principle areas; Engineering, Research and Development, Manufacturing, Repair and Overhaul, Quality Assurance and Administrative processes. Engineering Engineering Valcom's engineering facility has the personnel, the equipment and the expertise required to perform microprocessor-based development, communications, data collection hardware, interface and installation kit designs and other electrical/mechanical hardware design, as well as, prototyping, testing and debugging. An example of one of Valcom's designs is shown below. Valcom also has a complete software development facility consisting of both single-user and multi-user systems for various high level languages, including JAVA, HTML, C/C++, PASCAL, BASIC and FORTRAN. Valcom's software developers are fully capable of developing software compatible with both UNIX and Windows-based operating systems, as well as, developing embedded firmware using DSP methods and a variety of assemblers for a host of processors. The Engineering Department continually works at making improvements to existing products for the United States Navy, Air Force, Army and Coast Guard, as well as, for Canada's Department of National Defence, Coast Guard and Fisheries & Oceans Departments. Research and Development Research and Development For the past 30 years, Valcom has been committed to continued Research and Development including new product development and current product redesign. Improving performance characteristics, expanding product capabilities and increasing overall customer satisfaction are always the top priority of Valcom's R & D. As well, new product development to maintain competitiveness in the field of electronics communications and data acquisition remains a high priority. The HDR (High Data Rate) GOES (Geostationary Operational Environmental Satellite) transmitter project represented a totally new design to replace the original GOES transmitter that had been in use for fifteen years. This new Valcom product transmits weather and environmental data from remote locations to one of the GOES satellites, which relays the signal to a ground station. This project involved UHF amplifier design to produce a lab quality signal with extremely low distortion. The requirement was that noise components be at least 60 dB below the signal level. Additionally, the modulated signal was kept within a very narrow 1.5 KHz channel at a carrier frequency of 402 MHz. Data was encoded as eight levels of phase shifting from 0 to 315 degrees. Total phase noise from all sources was below 2.5 degrees RMS to achieve an extremely low bit error rate (BER). High Data Rate Transmitter VGOES-HDR Optimal phase pulse shaping, under microprocessor control, produced the best compromise between signal bandwidth and phase noise. The modulated carrier was generated using direct digital synthesis, rather than using the older technology of analog mixers and phase lock loops. We now meet all of the stringent requirements of the National Oceanographic and Atmospheric Administration for the use of our transmitter with their GOES satellites. Manufacturing of the GOES transmitter will also be performed at Valcom, Guelph. A device similar to a laptop was recently developed by Valcom under contract with another company. Paper-based activities, such as printing, scanning and faxing were integrated into a portable machine, so that travelling workers do the same work as they would back at their base office. A computer motherboard was designed to run a Windows operating system and to interface with the video, keyboard, scanner, printer, and communications ports. The required user interface software was developed in the C++ and JAVA programming languages Valcom regularly develops new antenna designs for a large variety of military and civilian applications and frequency ranges. Military antennas must be built to withstand greater mechanical and environmental stress, so the testing of each new product is exacting and thorough. One such antenna is Valcom's new VMB-3512. This is a tactical, vehicular-mounted VHF-UHF whip antenna. The antenna is designed to be mounted on a military vehicle and provides omni-directional transmit and receive communications over the frequency band of 30 MHz to 512 MHz. The VMB-3512 is a dipole-based design that means it has improved gain characteristics over that of a monopole design and it is not dependant on a ground plane, so it is ideal for all vehicle types. The antenna was tested at Valcom's facility and passed the stringent oak beam test, as well as all other popular mechanical and environmental requirements from MIL-STD-810. Valcom is currently developing a 30 MHz to 6,000 MHz antenna. This fully functional prototype performed printing, scanning, faxing, and web surfing functions. VMB-3512 Multi-BandAntenna The VEDAS II is an example of a product that has been continually improved over time.

Valcom was contracted to finish the development and to manufacture the various components of this system. Each attribute of the weather, rain, temperature, humidity, etc., has its own special module which talks to its dedicated sensor, analyses the data and sends it off to a central reporting station via telephone, hardline or wireless. All together, there are twelve different modules enclosed in a mainframe cabinet, working together to collect data, process it and transmit it. AWOS Automatic Weather Observation System On occasion, Valcom has since received further contracts for upgrading some of the modules used in the system. Such as the voice generator module and the pressure module. This project was developed for Atmospheric Environmental Services (now called MSC -Meteorological Services Canada). Valcom Environmental Data Acquisition System II (VEDAS II) Valcom Environmental Data Acquisition System II (VEDAS II) In 1997 Valcom began developing a new and improved data acquisition system from its original design (also a Valcom design). The VEDAS II can be interfaced with various sensors requiring serial communication, analog control voltages, or even frequency communication. It is ideal for remote situations in which automated sensor readings, such as temperature or water level, are measured and recorded. The information can then be accessed by telephone or via the GOES satellite network. This particular contract was a standing offer to build and supply over 285 VEDAS II data loggers over a period of two years. In total, over 600 units have been built and commissioned to the field. Valcom Environmental Data Acquisition System ll (VEDAS ll) The units are manufactured for Atmospheric Environmental Services (now called MSC - Meteorological Services Canada), as well as for Canada's Department of Water Resources and B.C. Hydro. U.S. Navy Antenna Groups U.S. Navy Antenna Groups In 1990, Valcom was approached to develop a series of antenna groups for Naval use. The antennas were to be designed using aluminum radiators opposed to fibreglass radiators. As part of the development, the antennas were to be used in a twin-whip configuration, complete with the necessary tuners and couplers to obtain broadband operation. In total, there were four groups designed: a 14 foot twin whip and coupler group, a regular duty 18 foot twin whip and coupler group, a light duty 18 foot twin whip and coupler group and a 35 foot twin whip and coupler group. As well, a broadband VHF dipole antenna for shipboard use was also developed. The antenna groups were originally designed and supplied for the U.S. Navy, SPAWAR (Space and Naval Warfare Systems Command) but have since been built and sold to Naval divisions world-wide. These antennas and couplers are still under production today. Heater Test Stand Heater Test Stand In 1990, Valcom was contracted to develop a Test Stand to assist with the repair and maintenance procedures of air and coolant fired heaters. The HTS allows for the heater to be removed from the vehicle and safely operated in a controlled environment. The test stand was originally developed almost ten years earlier by Valcom for the Canadian Department of National Defence. However, new heaters had since been commissioned and parts required for production had since become unavailable. The new units were developed for the U.S. Army TACOM (Tank Automotive Command) and are still being manufactured today. VHTS Series - Heater Test Stand In 1995, Valcom was contracted to modify the heater test stand for use with alternate heaters not supported by the previous models. These units were developed and manufactured for General Motors of Canada, Diesel Division. AS-3900A/VRC Antenna AS-3900A/VRC Antenna In 1994 Valcom was selected to manufacture and perform First Article Testing on the AS-3900A/VRC antenna for SINCGARS (Single-Channel Ground and Airborne Radio System). The antenna is a single port, centre-fed whip antenna for vehicular operation in the 30 to 88 MHz frequency band. Over 10,000 antennas were manufactured and delivered under this contract for the U.S. Army, CECOM (Communication-Electronics Command). As well, since this contract, Valcom has continued to manufacture this antenna for both the United States and Canadian Militaries and the antenna is still under production today. AS-3900A/VRC Additional Experience Additional Experience Expanding on Valcom's extensive experience, other jobs and projects include building headsets/handsets, designing and building cable adaptors, modifying tie-down clips, modifying power cable assemblies, and many other items. Valcom has also, in the past, purchased equipment and products from other companies and incorporated them into our own product line. One such example is Valcom's first GOES (Geostationary Operational Environmental Satellite) transmitter, model 697. The original design and associated commercial rights were purchased from Bristol Aerospace and was improved upon for use with the VEDAS units. The GOES transmitters were manufactured for many years until some of the key components had become obsolete and impossible to find. Valcom has recently completed a research and development project to redevelop a new GOES transmitter capable of meeting today's high data rate transmission requirements. This new transmitter is now certified by the National Environmental Satellite, Data and Information Service (NESDIS) and is in full production As well, Valcom remains a major worldwide producer/supplier of fibreglass whip antennas ranging from Medium Frequency (MF) to Ultra High Frequency (UHF) applications.
