#HAMRadio #EmergencyCommunicationsFrequencies how many #AmateurRadio know them and more importantly, how many know how to operate on these frequencies? 🤔 This IS the question! #IARU #CyRComms https://lnkd.in/ey2C2AYh
Gulfsat Communications has signed an important partnership with Es'hailSat - the Qatar Satellite Company for transponder services on Es’hail-1. This collaboration marks a significant advancement in satellite communication technologies.

VHF Marine Radio The most popular way of communicating at sea is via a marine VHF (Very High Frequency) set. These are combined transmitter/receivers that operate on allocated frequencies known as ‘channels’. Marine VHF radios are used for a variety of purposes including; contacting harbours, marinas, locks, summoning the rescue services and ship-to-shore or ship-to-ship communication. To prevent maritime transmissions creating interference with other radio users, a section of the radio spectrum has been allocated specifically for marine communications. To make operation within the spectrum as simple as possible, radio frequencies have been organised into numbered channels (eg. Ch.16 actually refers to156.800MHz).The VHF marine radio band remains consistent around the world, ensuring that vessels travelling on international voyages can always communicate. There are 55 international marine channels, a similar number of private channels (allocated on a local basis to commercial organisations), and some unique national channels. Channel 16 (156.800MHz) is the international calling and distress channel. Alpha Supply Ltd has all the necessary types of radio stations for your needs. #marineradio #gmdss #atexradio #handheldradio #walkietalkie
Nedaa will deploy its robust TETRA radio communication system, which ensures secure and reliable voice and data exchanges for rapid coordination among emergency responders. https://ow.ly/G4he50UxPXs
The PTA has cautioned that internet and broadband services in Pakistan might face disruptions due to a cable fault near Qatar. The issue involves the AAE-1 submarine cable, a key link for Pakistan's international internet connectivity. Efforts are underway to resolve the problem, with the PTA actively monitoring the situation. #PTA #Pakistan #DailyMagazine
The rapid growth of the VSAT industry is mainly driven by commercial, maritime, and rural communication. Enterprises in these industries depend on cost-efficient yet reliable satellite telecommunication services to stay connected and run their daily operations. Is your company using VSAT services? SIMPLY. CONNECT. COMMUNICATE. #northtelecom #satellitecommunication #vsat #satelliteinternet
The ACMA has issued its long-awaited guidance for LEOSat licensing arrangements for direct-to-mobile in IMT bands (called 'Supplemental Coverage from Space' or SCS in the United States). Notably, it confirms initial reliance on ITU Radio Regulations Article 4.4. for the space objects and that the existing terrestrial spectrum licence framework is sufficient for mobile handsets to communicate with the LEOSats. A key clarification is that space objects cannot be authorised to transmit under section 68 of the Radiocommunications Act since they are outside the area of the spectrum licence. Though, reliance on RR4.4 means that the LEOSats will be able to operate nonetheless. https://lnkd.in/gREQTxut
RABC will be reviewing SRSP-500, issue 2 (draft), “Technical Requirements for Land Mobile and Fixed Radio Services Operating in the Bands 138-144 MHz and 148-174 MHz”. SRSP-500 sets forth the minimum technical requirements for the purpose of efficient spectrum utilization for land mobile and fixed point-to-point systems operating in the Very High Frequency (VHF) bands 138-144 and 148-174 MHz. The following are the main changes: Removed mentions of the redeployment plan policy Updated the frequency range designated for the maritime mobile service Updated conditions for assignments within designated frequency bands Added conditions on the use of the Search and Rescue Interagency Frequency Added conditions to gradually adopt VHF public safety interoperability channels Added conditions on the use of frequencies assigned to Weatheradio systems Added requirements for minimum spectrum efficiency Added requirements for combining certain band edge channels for duplex operation Modified the definition of Simplex Block F and adjusted channels accordingly Modified the definition of Simplex Block G and adjusted channels accordingly Modified the definition of Simplex Block H and adjusted channels accordingly Modified the definition of Duplex Block H and adjusted channels accordingly Made corrections, editorial changes and clarifications, as appropriate. This standard was last updated (and first published) in 2004. https://lnkd.in/e6Cc3ktZ
