Long-distance Encrypted Radio Communication

Given that members of the National Civil Defence are spread across diverse locations and environments throughout Australia, long-distance encrypted radio communication is crucial for ensuring secure and reliable connectivity, particularly during emergencies or crises.

The initiative seeks to upgrade existing firearm ranges nationwide by implementing the essential infrastructure that will allow these EMP-protected facilities to serve as local hubs. These hubs will be equipped with multiple mobile stations to facilitate long-distance communications in remote areas across Australia.

 

Here are some options that could be considered:

  1. HF Radio Systems :
    • Icom IC-7610 : This is a high-performance HF transceiver that is widely used in both amateur and professional settings. It supports digital modes that can be encrypted, making it suitable for secure communications over long distances.
    • Yaesu FTdx101D : This HF transceiver offers advanced features for high-frequency communications and can support digital modes that enhance security through encryption.
  2. Digital Mobile Radio (DMR) :
    • Motorola MOTOTRBO : This series offers encrypted voice communications over long distances using digital mobile radio technology. DMR can be deployed for civil defense, providing efficient and secure communications.
  3. Satellite Communication Systems :
    • Inmarsat IsatPhone 2 : While primarily a satellite phone, it can work with data encryption services for secure long-distance communication.
    • Iridium Certus : This satellite communication service offers global coverage and can be used for voice and data communication with secure transmission options.
  4. VHF/UHF Systems with Encryption :
    • Kenwood NX-5000 Series : These radios are capable of operating on both VHF and UHF frequencies and can be equipped for encrypted communications, making them versatile for civil defense applications.
    • Hytera PD7 Series : These DMR radios offer encryption options and are well-suited for emergency response teams, enabling secure communications in various environments.
  5. Software-Defined Radios (SDRs) :
    • SDRs allow for flexible communication setups and can be programmed to use various encryption protocols, ideal for evolving communication needs in a civil defense context.
    • HackRF One or similar : While typically a hobbyist device, with proper software and coding, SDRs can encrypt and transmit various signals securely.
  6. Mesh Networking Radios :
    • goTenna Mesh : These devices allow for encrypted communications between units without relying on traditional infrastructure. They are useful in areas where conventional networks fail.
    • Raspberry Pi-based Mesh Networks : Custom setups using Raspberry Pi devices with radio modules to create encrypted mesh networks can be explored for adaptable and flexible communication.

Considerations

  • Interoperability : Ensure that any selected radio system can communicate with other existing government and emergency services’ communications networks.
  • Training : Personnel should be trained in the operation of these radios and encryption protocols to ensure effective use in emergency situations.
  • Regulations : Any equipment used must comply with Australian Communications and Media Authority (ACMA) regulations and guidelines for radio communications.

By integrating secure long-distance radio communication systems into the Australian Civil Defence Force, the capability for robust and resilient communication can be significantly enhanced, ensuring that critical information is transmitted securely during emergencies.
