A quick, organized response to an emergency can save lives, but making sure that the various groups involved in any operation can communicate effectively is not always easy because interoperability issues. The Communications Research Centre Canada (CRC) is working on technologies that help to address this problem. In responding to an emergency situation, be it a natural disaster or a terrorist attack, many different groups are normally called in to respond. Fire services, police, paramedics, military and many others all converge, and need to work together. However, often they struggle to communicate with each other since each group often has their own communications systems and radio technologies, which may not work with one another. New communication systems are helping to address this interoperability challenge. CRC is developing a number of these new technologies, including Software Defined Radio and Mobile Ad Hoc Networks. Both of these systems are designed to allow responders from multiple groups to quickly and easily establish a communications network in an emergency situation when they arrive on site, even with dissimilar radio systems.

Section 2 . Radio Communications Phraseology and Techniques . General a. Radio communications are a critical link in the ATC system. The link can be a strong bond between pilot and controller or it can be broken with surprising speed and disastrous results. Discussion herein provides basic procedures for new pilots and also highlights safe operating concepts for all pilots. b. The single, most important thought in pilot-controller communications is understanding. It is essential, therefore, that pilots acknowledge each radio communication with ATC by using the appropriate aircraft call sign. Brevity is important, and contacts should be kept as brief as possible, but controllers must know what you want to do before they can properly carry out their control duties. And you, the pilot, must know exactly what the controller wants you to do. Since concise phraseology may not always be adequate, use whatever words are necessary to get your message across. Pilots are to maintain vigilance in monitoring air traffic control radio communications frequencies for potential traffic conflicts with their aircraft especially when operating on an active runway and/or when conducting a final approach to landing. c.

Home Products and Services Communications Systems and Equipment Dicom DICOM - TACTICAL RADIO COMMUNICATION AND SATELLITE NAVIGATION SYSTEMS The DICOM products are developed and tested according to worldwide accepted standards (ISO, MIL-STD, STANAG, etc). DICOM uses its own modern technologies and methods of management in the development and production and also applies an effective quality control system, certified according to ISO 9001 and AQAP 110. The high production quality, servicing support and maximum orientation towards customers represent the main strategy of DICOM. VHF COMMUNICATION SYSTEMS The principal product line of the company consists of the VHF tactical communication system, based on the RF 13 manpack transceiver. It answers all requirements of tactical communication (handheld and manpack transceivers, mobile/base installations, modems, encryption units, radio data terminals, automatic rebroadcast systems, remote control, CNRI, co-site filters) and accessories (antennas, charges, analogue and digital field phones and many more). NEW: RF20 Handheld ECCM Transceiver - The RF20 handheld transceiver is a new type of communications tool, using latest digital technologies. These technologies feature secure data transmission (COMSEC), anti-detection and anti-jamming protection (TRANSEC). The transceiver operates in HF and VHF bands including Airband (Multiband) and comprises many special features (Multirole and Multimode). There are frequency hopping (FH), digital fixed frequency (DFF), free channel search (FCS) and FH/FCS – mixed modes (MIX). During FH operation in the tactical band, continuous monitoring of the 121.500MHz emergency frequency takes place. The transceiver has a simple 12-key control panel with an graphical LCD display indicating the operating status and displaying short text messages (SMS).

As it turns out, the typical application circuit is not bad - would I go so far as to say hi-fi in the audiophile sense? Perhaps - with caveats. It has good noise and distortion figures, and is remarkably simple to build if you have the PCB. Posted on in New Posts in CircuitBook More from this category Build a Basic Stamp Lightning Activity Monitor Uses a Basic Stamp 2 to display the number of lightning strikes per minute on a row of 8 LEDs. Depending on the mounting configuration, the lightning sensor is capable of detecting lightning strikes greater than 50 miles away. The strikes-per-minute method allows the users to not only determine the magnitude of the lightning activity, but also if the storm is approaching or traveling away. By monitoring the LEDs, increasing values indicate that the storms getting closer, while decreasing values (LEDs) indicate the storm is moving away.

The technology and actual construction of these radios is extremely advanced and intricate. I have a background in both mechanic and electronic engineering and work with product development - many of my ideas have come from my experiences with the radios. I would very much like more information about these and similar radios. Any help would be most gratefully received - please send info or comments to: mail Lt. Henning (USA air force) wrote in 1946: The mechanical design shows great skill and proficiency though it is sometimes expensive and heavy. Standardization of components has been achieved to a large extent, sets being built by the extensive use of complex magnesium alloy die castings. This enables the necessary stability to be obtained without employing crystal control, which is rarely used. All important units are readily detachable from their mounting frames for servicing, replacements, etc, connections being
