The Wireless Institute of Australia (WIA) provides an official directory and database of Australian amateur radio repeaters, detailing their locations, frequencies, and operational status. The resource includes downloadable files in PDF and CSV formats, along with a _Google Earth KMZ_ file for visualizing repeater sites across Australia, including Amateur, CB, and Marine repeaters. It also references external resources for various digital modes such as _IRLP_, _Echolink_, _D-STAR_, P25, Fusion, and DMR, providing links to their respective information sites. The WIA repeater data is cross-referenced with the _ACMA database_ to ensure accuracy, with updates typically occurring twice a year. The directory employs a color-coding system, where purple indicates repeaters carrying the WIA broadcast or callback channels, and a 'W' status denotes operational repeaters with the weekly WIA broadcast. The resource also outlines policies for removing unlicensed or non-operational repeaters from the PDF listing after specific timeframes, while retaining them in the CSV file for potential reinstatement.

The *SPACE* Amateur Radio over Internet Protocol (RoIP) system offers public audio transmissions from NASA Mission Control and astronauts, primarily for educational purposes. This service streams NASA public media sources, including *Artemis II* and the ISS public audio channel 2 feed, which predominantly features English communications. Astronaut activities on the ISS typically occur between 0700 UTC and 19:00 UTC, with transmissions most common during early mornings USA time, alongside special events such as launches or spacewalks. Users can connect to the live stream via EchoLink to the *SPACE* conference, via IRLP to the 0100 experimental reflector, or via Allstar to node 516221. EchoLink connections utilize the GSM CODEC, while IRLP and other connections default to uncompressed or u-law CODEC. The service notes that long periods of silence are common, and NASA audio sources can be periodically unavailable or noisy. Daily recordings of these transmissions are published at space.rfnet.link/recordings/, available as .ogg audio files for direct playback or .m3u8 playlist files for network streaming in applications like VLC. Each playlist file provides a list of timestamped audio transmissions, allowing users to review specific segments of interest.

Connecting to the global *EchoLink* network via a web browser simplifies internet linking for licensed amateur radio operators. This web application provides a direct interface, eliminating the need for client software installation. Users can log in with their validated callsign and password to access the system, facilitating contacts with other stations, repeaters, and conferences worldwide, much like traditional VoIP applications but tailored for amateur radio. The interface offers essential controls for managing connections, including selecting specific stations or conferences from a dropdown list, initiating a connection, and disconnecting. Features such as a 'Call CQ' button allow users to signal their availability for a contact, while options for low bandwidth operation and accepting incoming connections optimize performance and accessibility. Audio device selection ensures proper microphone and speaker integration with the web client. Validation of an amateur radio license is a prerequisite for full access, ensuring that only authorized operators utilize the network. The system prompts unvalidated users to provide an email address and password to begin the validation process, which typically involves submitting proof of license. This free service extends the reach of amateur radio communications globally, bridging geographical distances through internet connectivity.

Over 200 distinct 2-meter band amateur radio repeaters are cataloged for Australia, providing essential operational data for VHF communication. Each entry specifies the repeater's output frequency, often including the input tone (e.g., **91.5 Hz** or **123.0 Hz** CTCSS) and the repeater's callsign (e.g., _VK2RSC_, _VK3RHF_). Locations are precisely noted, frequently referencing specific towns, mountains, or geographical features such as "Kinglake, Kangaroo Ground" or "Adaminaby, Mars Hill." The resource also indicates various digital modes and linking capabilities where applicable, such as "FMEchoLinkFusionWIRES-X" or "DMR," alongside standard FM operation. This detailed listing facilitates local and regional VHF communication, enabling hams to program their transceivers accurately for repeater access. The data is presented in a clear, tabular format, making it straightforward to identify repeaters by frequency and location.

MeshCom 4.0 facilitates off-grid text messaging and data exchange via _LoRa_ radio modules, operating on low-power, low-cost hardware to establish networked communication capabilities. The system transmits messages, GPS positions, sensor values, and telecontrol data over significant distances with minimal power consumption. MeshCom modules can autonomously form a mesh network or integrate into a broader message network through MeshCom gateways, which ideally connect via _HAMNET_ to link disparate radio networks. Recent updates include MCMAP features, support for Lilygo T-Connect-Pro, and new firmware for T-ECHO, enhancing the system's versatility. The project provides basic specifications, detailed protocol information, and installation instructions for MeshCom 4.0, including guides for RAK WisBlock and HELTEC V3 hardware. Firmware and companion Android/iPhone applications are available for download, supporting a range of **10-20 km** line-of-sight communication.

Operating an **Echolink** gateway on the 4-meter band presents unique opportunities for extending VHF communications, as demonstrated by the EI4FMG node. Situated at Fieldstown, Monasterboice, this gateway provides coverage across a significant portion of Ireland's east coast, leveraging a Tait TM8100 radio and an EI4JR Echolink interface logic. My own experience with similar setups confirms the importance of strategic site selection for maximizing reach, particularly with a 122-meter elevation above sea level. Access to the EI4FMG gateway, identified by node 57006, requires a **CTCSS** tone of 88.5 Hz, a standard practice for managing access and minimizing interference on shared frequencies. The system transmits with 15 watts of power and utilizes a Sigma CAT70 @5MAGL antenna, a configuration well-suited for regional VHF coverage. The gateway also features an auto-ID every 8 minutes, ensuring compliance and clear station identification. Users can interact with the gateway using various DTMF commands, allowing for connections to specific nodes, random repeater/link or conference nodes, and managing disconnections. These functionalities streamline the process of linking into the broader Echolink network, enabling local VHF operators to communicate globally through the internet backbone.
