FT2 is an innovative digital mode for amateur radio, developed by IU8LMC with support from ARI Caserta. It utilizes the same codec as FT8 and FT4 but compresses the transmission cycle to just 3.8 seconds, allowing for a complete QSO in as little as 11 seconds. This remarkable speed enables operators to achieve approximately 240 QSOs per hour, making it particularly advantageous for contests and DXpeditions. The FT2 protocol has been rigorously tested on-air, with successful QSOs verified down to -12 dB SNR on both 40m and 80m bands. The mode's efficiency and speed are a significant advancement in digital communications, providing a new tool for amateur radio operators looking to maximize their contact rates. As an experimental release, the software is subject to updates, ensuring continuous improvement and adaptation to user feedback.

The IZ3MEZ Web DX Cluster presents real-time amateur radio DX spots across 20 distinct frequency bands, spanning from **LF (2190m)** at 135.7 kHz up to **SHF (QO-100)** at 10499 MHz. It displays the DX callsign, frequency, DXCC entity, spotter callsign, and spotter DXCC entity, along with any accompanying comments. The cluster also lists various operating modes such as CW, RTTY, FT8, FT4, FT2, PSK, and SSTV, and supports special operating activities like QRP/P and specific award programs including IOTA, POTA, SOTA, WCA, and JOTA. The cluster's interface provides a dynamic feed of the latest 50 spots, continuously updated with precise timestamps. It offers direct **Telnet protocol** access for users preferring a command-line interface, with configuration instructions provided. The resource also integrates with other spotting networks like RBN and PSK Reporter, enhancing its utility for DXers and contesters seeking propagation information and activity monitoring across a broad spectrum of amateur radio frequencies.

DecoAlert 1.0 Beta is a companion application designed to enhance the digital mode operating experience, specifically for FT8, FT4, and FT2. It operates by monitoring UDP data streams from primary decoding software like _Decodium_ and _WSJT-X_ on port 2237. The software provides real-time, priority-based audio alerts using WAV sounds for various conditions, including All Time New Ones (ATNO), new DXCC entities per band/mode, user-defined watchlist callsigns, new Maidenhead grid squares, and LoTW-active stations. It also highlights previously worked stations (B4) and integrates live DX spots from Telnet clusters, offering a comprehensive suite of tools for serious digital mode operators. The application features a built-in SQLite database for tracking worked stations and integrates with LoTW user lists to identify confirmed contacts. A DX Cluster client supports multiple Telnet servers, providing a broad view of propagation. PSKReporter statistics are available by band and mode, offering insights into signal paths. The QSO log viewer includes search and filter capabilities, while an _OpenStreetMap_ (OSM) interface visualizes spot locations, aiding in situational awareness. DecoAlert requires Windows 10/11 (64-bit) and compatible digital mode software configured to send UDP data.

Presents the NED International DX Group, a **CB radio** organization established in the Netherlands on August 23, 2026, by 19NED000 and 19NED001 Henricus. The group primarily operates on the **11-meter band**, utilizing various modes including FM, AM, LSB, USB, CW, FT8, FT4, FT2 Ross, and JS8, with all digital modes permitted. Membership is free and open to active operators and SWLs. Key operating frequencies include 27.405 LSB, 27.265 USB for FT8, and 27.245 USB for JS8. The group also maintains activity on PMR Channel 10 at 446.11875 MHz FM. The organization is actively seeking volunteers for roles such as webmaster (proficient in PHP, MySQL, and security), digital eQSL and paper QSL card management, logo and banner design, and country/province directors.
